PART I
ITEM 1
Business
Introduction
American Financial Group, Inc. (“AFG” or the “Company”) is a holding company that, through the operations of Great American Insurance Group, is engaged primarily in property and casualty insurance, focusing on specialized commercial products for businesses, and in the sale of fixed and fixed-indexed annuities in the retail, financial institutions and education markets. Its 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.
Property and Casualty Insurance Segment
General
AFG’s property and casualty insurance operations provide a wide range of commercial coverages through over 30 niche insurance businesses 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 employed approximately 6,700 people as of December 31, 2017. These operations are conducted through the subsidiaries listed in the following table, which includes independent financial strength ratings and 2017 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.

Mid-Continent Casualty | A+ |  | A+ |  | 131 |
Other |  |  |  |  | 102 |

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 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
2

Table of Contents
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 the 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 94% of AFG’s direct written premiums in 2017, 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.
AFG’s statutory combined ratio averaged 92.0% for the period 2015 to 2017 as compared to 101.4% for the property and casualty industry over the same period (Source: “A.M. Best’s Review & Preview Report” — February 2018 Edition). 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.

Table of Contents
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 $140 million in 2017, $55 million in 2016 and $35 million in 2015 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 the purchase of reinsurance. AFG’s net exposure to a catastrophic earthquake or windstorm that industry models indicate could occur once in every 500 years (a “500-year event”) is expected to be less than 4% 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:

Property and Transportation |
Inland and Ocean Marine | Provides coverage primarily for builders’ risk, contractors’ equipment, property, motor truck cargo, marine cargo, boat dealers, marina operators/dealers and excursion vessels.
Agricultural-related | Provides 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 | Provides coverage for vehicles (such as buses and trucks) in a broad range of businesses including the moving and storage and transportation industries, and a specialized physical damage product for the trucking industry.
Specialty Casualty |
Executive and Professional Liability | Markets coverage for directors and officers of businesses and non-profit organizations; errors and omissions; cyber; and mergers and acquisitions.
Umbrella and Excess Liability | Provides liability coverage in excess of primary layers.
Excess and Surplus | Provides 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.
General Liability | Provides coverage for contractor-related businesses, energy development and production risks, and environmental liability risks.
Targeted Programs | Includes 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.
Workers’ Compensation | Provides coverage for prescribed benefits payable to employees who are injured on the job.
Specialty Financial |
Fidelity and Surety | Provides 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 | Provides 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 their 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.

Premium Distribution
The following table shows the net written premiums by sub-segment for AFG’s property and casualty insurance operations for 2017, 2016 and 2015 (in millions):

| 2017 |  | 2016 |  | 2015
Property and transportation | $ | 1,765 |  |  | $ | 1,672 |  |  | $ | 1,636 |

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 one of two bases, facultative or treaty. 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, 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 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 $100 million (per occurrence and annual aggregate) occurring between June 1, 2017 and 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. 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
5

Table of Contents
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.
In January 2018, Neon launched NCM Re (UK PCC) Ltd. (“NCM Re”), the first insurance-linked securities (“ILS”) vehicle in the United Kingdom (“UK”). NCM Re utilizes recently approved UK regulations to provide Neon with the ability to further enhance its global reinsurance offering to clients. NCM Re plans to use a range of catastrophe modeling and pricing techniques to make use of Neon’s underwriting and risk selection skills to source business for third-party ILS investors in the capital markets. In early 2018, NCM Re completed its first ILS transaction, which provides $72 million in collateralized quota share reinsurance that will assume 20% 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, Neon also placed a 35% quota share reinsurance treaty covering its property insurance (but not assumed reinsurance) lines.
Also in January 2018, AFG’s property and casualty insurance subsidiaries renewed 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 but as part of the placement, eliminated its 5% participation from previous treaty years. Neon placed $200 million of coverage in excess of a $15 million per event primary retention (extending to $225 million for U.S. risks only) with a 7.5% participation. For the catastrophe excess of loss reinsurance coverage, recoveries from NCM Re and Neon’s property insurance quota share apply before calculating losses recoverable from the catastrophe excess of loss reinsurance treaty. In addition to Neon’s catastrophe excess of loss reinsurance coverage, Neon has placed a quota share treaty which covers 12.5% of Neon’s gross property losses with a $400 million event limit (maximum $50 million recoverable) which supplements its catastrophe excess of loss reinsurance coverage and property quota share coverages up to the event limit.
The commercial marketplace requires large policy limits ($25 million or more) in several of AFG’s lines of business, including certain 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 10% of AFG’s total property and casualty reinsurance recoverable (including prepaid reinsurance premiums and net of payables to reinsurers) at December 31, 2017: 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 $156 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.

(b) | Maximum loss per event for claims up to reinsurance coverage limit.

(c) | Coverage amount extends to $225 million for U.S. catastrophe events. The combination of Neon’s excess of loss catastrophe reinsurance and 12.5% gross property loss treaty (discussed above) limits the maximum retained loss per event to $15 million until such coverage is exhausted.

(d) | Includes aggregate coverage. See description above.

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 2017 and 2016, AFG reinsured 52.5% 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 2018, 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 $100 million on paid losses and LAE and $2.96 billion on unpaid losses and LAE at December 31, 2017. These amounts are net of allowances of approximately $20 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):

|  | 2017 |  | 2016 |  | 2015
Reinsurance ceded |  | $ | 1,751 |  |  | $ | 1,595 |  |  | $ | 1,505 |
Reinsurance ceded, excluding crop |  | 1,076 |  |  | 985 |  |  | 899 |
Reinsurance assumed — including involuntary pools and associations |  | 192 |  |  | 123 |  |  | 119 |

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 O — “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.

Asbestos and Environmental (“A&E”) 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 — “Uncertainties — Asbestos and Environmental-related (“A&E”) Insurance Reserves” and Note M — “Contingencies” to the financial statements.
Management has periodically conducted comprehensive external studies of its asbestos and environmental reserves with the aid of specialty actuarial, engineering and consulting firms and outside counsel, generally every two years, with an in-depth internal review during the intervening years. Charges resulting from these studies and reviews are included in “Incurred losses and LAE” in the table below. As a result of the 2017 comprehensive external study, AFG recorded an $89 million pretax special charge in the third quarter of 2017 to increase the property and casualty group’s asbestos reserves by $53 million (net of reinsurance) and its environmental reserves by $36 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. Overall, the rate of new asbestos cases received is down modestly however, increasing life expectancies in the U.S. have allowed more time for the impacts of asbestos exposure to emerge. AFG’s comprehensive external study incorporated, among other factors, the increase in projected industry ultimate losses attributable to asbestos exposures, as well as revised estimates for future claims emergence, which resulted in an increase in AFG’s provision for future asbestos claims. The increase in property and casualty environmental reserves in 2017 (as well as in 2016, discussed below) was primarily associated with updated estimates of site investigation costs with respect to existing sites and newly identified sites. AFG is seeing increased legal defense costs in environmental claims generally, as well as a number of claims and sites where the estimated investigation and remediation costs have increased. Certain individual claims are taking a longer time to settle than originally estimated, causing AFG to increase its reserves to reflect related increased costs. As in past years, there were no new or emerging broad industry trends that were identified in this study. As a result of the 2016 internal review, AFG recorded a $36 million pretax special charge in the third quarter of 2016 to increase the property and casualty group’s asbestos reserves by $5 million (net of reinsurance) and its environmental reserves by $31 million (net of reinsurance). As a result of the 2015 comprehensive external study, AFG recorded a $67 million pretax special charge in the third quarter of 2015 to increase the property and casualty group’s asbestos reserves by $25 million (net of reinsurance) and its environmental reserves by $42 million (net of reinsurance). The increase in property and casualty environmental reserves in 2015 was attributed primarily to AFG’s increased defense costs and a number of claims where the estimated costs of remediation have increased.
The following table (in millions) is a progression of the property and casualty group’s A&E reserves.

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. They also compete 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 sells traditional fixed and fixed-indexed annuities in the retail, financial institutions and education markets through independent producers and through direct relationships with certain financial institutions. The annuity operations employed approximately 600 people at December 31, 2017. These operations are conducted primarily through the subsidiaries listed in the following table, which includes 2017 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 |  | $ | 4,130 |  |  | 402,000 |  |  | A |  | A+
Annuity Investors Life Insurance Company |  | 211 |  |  | 114,000 |  |  | 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.
Statutory premiums of AFG’s annuity operations for the last three years were as follows (in millions):

|  | Premiums
|  | 2017 |  | 2016 |  | 2015
Financial institutions single premium annuities — indexed |  | $ | 1,711 |  |  | $ | 1,950 |  |  | $ | 1,741 |

Education market — fixed and indexed annuities |  | 174 |  |  | 184 |  |  | 194 |
Total fixed annuity premiums |  | 4,313 |  |  | 4,398 |  |  | 4,098 |
Variable annuities |  | 28 |  |  | 37 |  |  | 42 |
Total annuity premiums |  | $ | 4,341 |  |  | $ | 4,435 |  |  | $ | 4,140 |

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.

Table of Contents
Annuity contracts are generally classified as either fixed rate (including fixed-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 assets and liabilities.
A fixed-indexed annuity provides policyholders with the opportunity to receive a crediting rate tied, in part, to the performance of an existing market index (generally the S&P 500) while protecting against the related downside risk through a guarantee of principal (excluding surrender charges, market value adjustments, and certain benefit charges). AFG purchases call options designed to substantially offset the effect of the index participation in the liabilities associated with fixed-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 fair value accounting for derivatives related to fixed-indexed annuities (“FIAs”) (dollars in millions):

|  | Year ended December 31,
|  | 2017 |  | 2016 |  | 2015
Annuity earnings before income taxes — before the impact of derivatives related to FIAs |  | $ | 413 |  |  | $ | 395 |  |  | $ | 354 |
Impact of derivatives related to FIAs (a) |  | (33 | ) |  | (27 | ) |  | (23 | )
Annuity segment earnings before income taxes |  | $ | 380 |  |  | $ | 368 |  |  | $ | 331 |
Net spread earned on fixed annuities — before impact of derivatives related to FIAs |  | 1.33 | % |  | 1.39 | % |  | 1.35 | %
Impact of derivatives related to FIAs |  | (0.10 | %) |  | (0.10 | %) |  | (0.09 | %)
Net spread earned on fixed annuities |  | 1.23 | % |  | 1.29 | % |  | 1.26 | %

(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 of call options on the appropriate index. AFG’s strategy is designed so that the change in the fair value of the call option assets will generally offset the economic change in the liabilities from the index participation. Both the index-based component of the annuities (fair value of $2.54 billion at December 31, 2017) and the related call options (fair value of $701 million at December 31, 2017) 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 fair value of the embedded derivative that management believes can be inconsistent with the long-term economics of these products.

Marketing
AFG sells its single premium annuities, excluding financial institution production (discussed below), primarily through a retail network of approximately 65 national marketing organizations (“NMOs”) and managing general agents (“MGAs”) who, in turn, direct nearly 1,100 actively producing agents.

Table of Contents
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 2017 statutory premiums):

| 2017 |  | 2016
The PNC Financial Services Group, Inc. | 9.1 | % |  | 9.7 | %
Wells Fargo & Company | 8.1 | % |  | 14.2 | %
Regions Financial Corporation | 6.5 | % |  | 4.8 | %
LPL Financial | 5.5 | % |  | 4.8 | %
BB&T Corporation | 5.5 | % |  | 4.5 | %

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 directly through writing agents rather than through NMOs and MGAs.
AFG is licensed to sell its fixed annuity products in all states except New York; it is licensed to sell its variable products in all states except New York and Vermont. At December 31, 2017, AFG had approximately 515,000 annuity policies in force. The states that accounted for 5% or more of AFG’s statutory annuity premiums in 2017 and the comparable preceding years are shown below:

|  | 2017 |  | 2016 |  | 2015
California |  | 10.0 | % |  | 9.8 | % |  | 9.7 | %
Florida |  | 7.3 | % |  | 8.5 | % |  | 9.0 | %
Pennsylvania |  | 6.1 | % |  | 7.2 | % |  | 7.2 | %
Ohio |  | 5.4 | % |  | 5.2 | % |  | 5.7 | %
Texas |  | 5.1 | % |  | 4.6 | % |  | 4.3 | %

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. 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.
Run-off Long-term Care and Life Segment
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. See Note B — “Acquisitions and Sale of Businesses” to the financial statements. Renewal premiums on the remaining policies covering approximately 1,600 lives will be accepted unless those policies lapse. At December 31, 2017, AFG’s long-term care insurance reserves were $39 million, net of reinsurance recoverables and excluding the impact of unrealized gains on securities.

Table of Contents
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 105,000 policies and $12.05 billion gross ($3.73 billion net of reinsurance) of life insurance in force at December 31, 2017. Renewal premiums, net of reinsurance, were $17 million in 2017, $18 million in 2016 and $28 million in 2015. At December 31, 2017, AFG’s life insurance reserves were $309 million, net of reinsurance recoverables.
Other Operations
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, 2017.

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 11% of AFG’s fixed maturity investments are MBS. At December 31, 2017, 98% (based on statutory carrying value of $37.01 billion) of AFG’s fixed maturity investments held by its insurance companies had a NAIC designation of 1 or 2 (the highest of the six designations).
Equity Investments
At December 31, 2017, AFG held common and perpetual preferred stocks classified as available for sale with a fair value of $1.60 billion.
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 2018 from its insurance subsidiaries without seeking regulatory approval is approximately $826 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 the European Union’s executive body, the European Commission. On January 1, 2016, Neon adopted new capital adequacy and risk management regulations known as Solvency II. Because Lloyd’s insurers were already operating under the proposed Solvency II guidelines, implementation was not material to AFG.
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.

Table of Contents
Disclosure of Certain Activities Under Section 13(r) of the Securities Exchange Act of 1934
Section 13(r) of the Securities Exchange Act of 1934, as amended (“Section 13(r)”), requires a registrant to disclose in its annual or quarterly reports whether it or an affiliate knowingly engaged in certain activities, transactions or dealings related to Iran during the period covered by the report. Many of the activities, transactions and dealings that are required to be reported under Section 13(r) were previously subject to U.S. sanctions or prohibited by applicable local law. On January 16, 2016, the United States and the European Union eased sanctions against Iran pursuant to the Joint Comprehensive Plan of Action, and many of the reportable activities, transactions and dealings under Section 13(r) are no longer subject to U.S. sanctions and no longer prohibited by applicable local law.
Certain of the Company’s subsidiaries located outside the United States subscribe to insurance policies that provide insurance coverage to vessels owned by international shipping and marine entities with vessels that travel worldwide. As a result, the insurance policies may be called upon to respond to claims involving or that have exposure to Iranian petroleum resources, refined petroleum, and petrochemical industries. For example, certain of the Company’s non-U.S. subsidiaries participate in global marine hull and war policies that provide coverage for damage to vessels navigating into and out of ports worldwide, which could include Iran.
For the year ended December 31, 2017, the Company is not aware of any additional premium with respect to underwriting insurance or reinsurance activities reportable under Section 13(r). Should any such risks have entered into the stream of commerce covered by these insurance or reinsurance activities, the Company believes that the premiums associated with such business would be immaterial.
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. For example, during the financial crisis that started approximately ten years ago, the United States and many other economies experienced a prolonged economic downturn, resulting in heightened credit risk, reduced valuation of certain investments and decreased economic activity. Financial markets may again experience significant and prolonged disruption, including disruption from unanticipated events. In the years following the financial crisis, the federal government has taken steps to stabilize financial markets, but such steps may not be effective.
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 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, 2017, 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 risk that 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.

Table of Contents
Interest rates have remained at historical lows for an extended period. In addition, central banks in some countries have recently pursued largely unprecedented negative interest rate policies, 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, 2017, mortgage-backed securities constituted approximately 11% 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 the profitability of AFG’s annuity business.
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 the Company’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 fixed-indexed deferred 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, the Company 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.
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., Baldwin & Lyons, 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), RLI Corp., The Travelers Companies, Inc., Tokio Marine Holdings, Inc. (HCC Insurance, Philadelphia Consolidated), W.R. Berkley Corp., 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, Sumitomo Life Insurance Company (Symetra Financial Corp.) and Voya Financial, Inc.
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.

Table of Contents
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 54% of AFG’s annuity premiums in 2017 and have been a key driver in the growth of AFG’s annuity business. In 2017, two large financial institutions accounted for 32% of AFG’s total sales through financial institutions and 17% 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. Accordingly, AFG must compete with other insurance carriers for independent agents’ business. Some of its competitors offer a wider variety of products, lower price 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, 2017, recoverables from reinsurances reported on AFG’s Balance Sheet were approximately $3.37 billion.
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). 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. Implementation of the Dodd-Frank Act is ongoing. The potential impacts of the Act on the U.S. insurance industry are not clear, but may affect AFG’s operations and governance in ways that could adversely affect 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. On December 22, 2017, the U.S. enacted The Tax Cuts and Jobs Act of 2017 (“TCJA”), which significantly reforms the U.S. tax code. AFG’s deferred tax assets and liabilities have been revalued as of December 31, 2017 to reflect the newly enacted corporate tax rate. The U.S. Treasury and the Internal Revenue Service are expected to issue implementation guidance for the TCJA in 2018. Clarifications and interpretations of the TCJA may adversely affect our expected effective tax rate and the realization of deferred taxes.
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 their potential impact, if any, on its insurance company subsidiaries.
On April 6, 2016, the U.S. Department of Labor (“DOL”) released a final regulation that substantially expands the range of activities that will be considered fiduciary advice under the Employee Retirement Income Security Act of 1974 and the Internal Revenue Code of 1986. The regulation’s scheduled effective date was April 10, 2017. This regulation deems advisers, including
16

Table of Contents
insurance agents, who sell annuities to IRAs, IRA rollovers or 401(k) plans to be fiduciaries and prohibits them from receiving compensation unless they comply with a prohibited transaction exemption requiring, among other things, advisers to comply with impartial conduct standards of acting in the customer’s best interest, making no misleading statements and receiving reasonable compensation. On February 3, 2017, President Trump issued a presidential memorandum directing the DOL to examine the regulation, and on April 4, 2017, the DOL announced “the delay rule” that deferred the effective date of the regulation until June 9, 2017, as it continued its examination as mandated by the President’s executive order. The rule further delayed certain requirements associated with prohibited transaction exemptions, other than the impartial conduct standards, under the final regulation until January 1, 2018. On November 29, 2017, the DOL extended this transition period another 18 months. As a result, insurance agents can continue selling fixed-indexed annuities through July 1, 2019, provided the agent complies with the impartial conduct standards. Regardless, during this transition period, the increased regulatory burdens and compensation changes required of agents to comply with the prohibited transaction exemptions may negatively impact AFG’s business, results of operations or financial condition. If the final regulation is fully implemented on July 1, 2019, compliance with the prohibited transaction exemptions will likely result in additional regulatory burdens, changes to AFG’s product offerings and increased litigation risk, which could negatively impact AFG’s business, results of operations or financial condition. Management cannot currently predict the effect on AFG’s business if the DOL’s examination mandated by the President results in the proposal of significant changes to the final regulation (or a further delay of the July 1, 2019 implementation date).
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 the Company.
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 TRIPRA provides benefits for certified acts of terrorism that exceed a certain threshold of industry losses ($140 million in 2017, increasing by $20 million annually to $200 million by 2020), those benefits are subject to a deductible and other limitations. In 2018, AFG would have to sustain losses from terrorism of over $670 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 computer virus, a terrorist attack or war, AFG’s systems may
17

Table of Contents
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 vulnerable to security breaches due to the sophistication of cyber-attacks, viruses, malware, hackers and other external hazards, as well as inadvertent errors, equipment and system failures, and employee misconduct. In addition, over time, and particularly recently, 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 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 protect the confidentiality of customer information could adversely affect AFG’s reputation and have a material adverse effect on AFG’s business, financial condition and results of operations.
AFG receives and is required to protect certain confidential information from customers, vendors and other third parties that may include financial information and, in connection with AFG’s property and casualty insurance operations, medical information. In addition, AFG and certain of its third-party vendors receive and store personal information in connection with AFG’s human resources operations and other aspects of AFG’s business. AFG is subject to numerous federal, state and international laws regarding the privacy and security of personal information, which laws vary significantly from jurisdiction to jurisdiction. 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.
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 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 loss adjustment expense 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 loss adjustment expenses is difficult to estimate. Unpaid losses and loss adjustment expense 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 loss adjustment expenses 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 or other 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 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 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.
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 asbestos and environmental 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.

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 (“DPAC”). These assumptions relate to investment yields (and spreads over fixed annuity crediting rates), benefit utilization rates, equity market performance, the cost of call options used in the fixed-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.
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.
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.
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 2017. If AFG cannot obtain adequate capital or sources of credit on favorable terms, or at all, its business, operating results and financial condition would 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.

Recent developments relating to the United Kingdom’s referendum vote in favor of leaving the EU could adversely affect AFG’s London-based property and casualty insurance operations.
The United Kingdom (“UK”) held a referendum on June 23, 2016 in which a majority of voters voted for the UK’s withdrawal from the European Union (“Brexit”). Because of this vote, the terms of the UK’s withdrawal from the EU and the relationship between the UK and EU going forward will have to be negotiated, including the terms of trade between the UK and the EU. The ultimate impact of Brexit is uncertain and will depend on any agreements that the UK makes to retain access to EU markets. Brexit could also lead to legal uncertainty and potentially divergent national laws and regulations as the UK determines which EU laws to replace or replicate. These or other adverse consequences from Brexit could adversely affect the operations and business opportunities of AFG’s Ireland-based property and casualty subsidiary and Neon, AFG’s London-based Lloyd’s syndicate.
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 12.1% of AFG’s outstanding Common Stock as of February 1, 2018. 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, including over matters requiring shareholder approval. Such concentrated ownership could prevent an acquisition of AFG at a price which other shareholders may find attractive.
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 2017, AFG’s Common Stock traded at prices ranging between $85.57 and $109.41. 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 670,000 square feet of commercial and office space in these buildings. A property and casualty insurance subsidiary occupies approximately 87% of the 164,000 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.

Table of Contents
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.

In May and November 2017 and November 2016, AFG declared additional special cash dividends of $1.50, $2.00 and $1.00 per share of AFG Common Stock, which were paid in May and November 2017 and December 2016, respectively. The ability of AFG to pay dividends will be dependent upon, among other things, the availability of dividends and payments under intercompany tax allocation agreements from its insurance company subsidiaries.
Issuer Purchases of Equity Securities AFG did not repurchase any shares of its Common Stock during the year ended December 31, 2017. There are 4,132,838 remaining shares that may be repurchased under the Plans authorized by AFG’s Board of Directors in December 2014 and February 2016.
AFG acquired 34,922 shares of its Common Stock (at an average of $94.07 per share) in the first nine months of 2017, 41 shares (at $103.80 per share) in October 2017 and 2,755 shares (at an average of $108.20 per share) in December 2017 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 investment 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) | Includes special cash dividends of $3.50 paid in 2017 and $1.00 per share paid in 2016, 2015, 2014 and 2013.

(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 earnings to fixed charges excluding annuity benefits was 7.67, 8.62, 6.58, 7.95 and 8.86 for 2017, 2016, 2015, 2014 and 2013, respectively. 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 appropriated retained earnings and net unrealized gains related to fixed maturity securities. Management believes that investors find a measurement of shareholders’ equity excluding these items to be meaningful as (i) 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 and (ii) appropriated retained earnings represents amounts that will ultimately inure to the debt holders of the collateralized loan obligations managed by AFG (see Note A — “Accounting Policies — Managed Investment Entities” to the financial statements).

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, 2017, AFG (parent) held approximately $369 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 fixed and fixed-indexed annuities in the retail, financial institutions and education markets.
Fourth quarter 2017 net earnings attributable to AFG’s shareholders were $166 million ($1.84 per share, diluted) compared to $385 million ($4.33 per share, diluted) in the fourth quarter of 2016, reflecting:

• | higher underwriting profit in the property and casualty insurance segment,

• | lower earnings in the annuity segment, resulting from the fair value accounting for fixed-indexed annuities,

• | lower net realized gains on securities in the fourth quarter of 2017 compared to the fourth quarter of 2016,

• | the fourth quarter 2017 loss on retirement of debt,

• | the fourth quarter 2017 tax benefit related to the Neon Underwriting Ltd. (“Neon”) restructuring,

• | the fourth quarter 2017 tax expense related to the change in the U.S. corporate tax rate and

• | the fourth quarter 2016 tax benefits from the National Interstate merger and Neon restructuring.

Table of Contents
Full year 2017 net earnings attributable to AFG’s shareholders were $475 million ($5.28 per share, diluted) compared to $649 million ($7.33 per share, diluted) in 2016, reflecting:

• | higher underwriting profit in the property and casualty insurance segment due primarily to higher favorable prior year reserve development,

• | higher earnings in the annuity segment,

• | higher profitability in the run-off long-term care and life segment,

• | lower realized gains on securities in 2017 compared to 2016,

• | the 2017 loss on retirement of debt,

• | the fourth quarter 2017 tax benefit related to the Neon restructuring,

• | the fourth quarter 2017 tax expense related to the change in the U.S. corporate tax rate,

• | the second quarter 2016 gain on the sale of an apartment property, and

• | the fourth quarter 2016 tax benefits related to the National Interstate merger and Neon restructuring.

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 recoverability of deferred acquisition costs,

• | 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, 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,
2017 |  | 2016
Principal amount of long-term debt |  | $ | 1,318 |  |  | $ | 1,308 |
Total capital |  | 6,033 |  |  | 5,921 |
Ratio of debt to total capital: |  |  |  |
Including subordinated debt |  | 21.8 | % |  | 22.1 | %
Excluding subordinated debt |  | 16.9 | % |  | 17.0 | %

The ratio of debt to total capital is a non-GAAP measure that management believes is useful for investors, analysts and independent 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) on fixed maturity investments).
27

Table of Contents
AFG’s ratio of earnings to fixed charges, including annuity benefits as a fixed charge, was 1.72 for the year ended December 31, 2017. Excluding annuity benefits, this ratio was 7.67. Although the ratio excluding annuity benefits is not required or encouraged to be disclosed under Securities and Exchange Commission rules, it 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, 2017, the capital ratios of all AFG insurance companies substantially 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,
| 2017 |  | 2016 |  | 2015
Net cash provided by operating activities | $ | 1,804 |  |  | $ | 1,150 |  |  | $ | 1,353 |
Net cash used in investing activities | (3,292 | ) |  | (2,981 | ) |  | (4,573 | )
Net cash provided by financing activities | 1,719 |  |  | 2,718 |  |  | 3,097 |
Net change in cash and cash equivalents | $ | 231 |  |  | $ | 887 |  |  | $ | (123 | )

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 $60 million in 2017 and reduced cash flows from operating activities by $279 million in 2016 and $190 million in 2015, accounting for a $339 million increase in cash flows from operating activities in 2017 compared to 2016 and an $89 million decrease in cash flows from operating activities in 2016 compared to 2015. 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 $1.74 billion, $1.43 billion and $1.54 billion in 2017, 2016 and 2015, 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 products. Net cash used in investing activities was $3.29 billion in 2017 compared to $2.98 billion in 2016, an increase of $311 million. As discussed below (under net cash provided by financing activities), AFG’s annuity group had net cash flows from annuity policyholders of $1.99 billion in 2017 and $2.35 billion in 2016, which is the primary source of AFG’s cash used in investing activities. Settlements of equity index call options exceeded purchases by $285 million in 2017 compared to purchases exceeding settlements by $110 million in 2016, accounting for a $395 million decrease in cash used in investing activities. In general, purchases of equity index call options have increased due to growth in the fixed-indexed annuity business while proceeds from settlements of equity options are impacted by the performance of the stock market during the term of the options. 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 $205 million use of cash in 2017 compared to a $364 million use of cash in 2016, accounting for a $159 million decrease in net cash used in investing activities in 2017 compared to 2016. See Note A — “Accounting Policies — Managed Investment Entities” and Note H — “Managed Investment Entities” to the financial statements.

Table of Contents
Net cash used in investing activities was $2.98 billion in 2016 compared to $4.57 billion in 2015, a decrease of $1.59 billion. The $151 million decrease in net cash flows from annuity policyholders in 2016 as compared to 2015 decreased the amount of cash available for investment in 2016 compared to 2015. In addition, AFG’s cash on hand increased by $887 million during 2016, primarily in the property and casualty and annuity segments reflecting the timing of investing available cash in those segments. Net investment activity in the managed investment entities was a $364 million use of cash in 2016 compared to a $675 million use of cash in 2015, accounting for a $311 million decrease in net cash used in investing activities in 2016 compared to 2015.
Net Cash Provided by Financing Activities AFG’s financing activities consist primarily of transactions with annuity policyholders, issuances and retirements of long-term debt, repurchases of common stock and dividend payments. Net cash provided by financing activities was $1.72 billion in 2017 compared to $2.72 billion in 2016, a decrease of $999 million. Annuity receipts exceeded annuity surrenders, benefits, withdrawals and transfers by $1.99 billion in 2017 compared to $2.35 billion in 2016, resulting in a $362 million decrease in net cash provided by financing activities in 2017 compared to 2016. In 2017, AFG issued $590 million of 4.50% Senior Notes due in 2047 and $125 million of 3.50% Senior Notes due in 2026, the net proceeds of which contributed $712 million to net cash provided by financing activities in 2017 compared to net proceeds from additional long-term borrowings of $302 million in 2016, which accounted for a $410 million increase in cash provided by financing activities in 2017 compared to 2016. Redemptions of long-term debt were a $745 million use of cash in 2017 and an $18 million use of cash in 2016, which accounted for a $727 million decrease in net cash provided by financing activities in 2017 compared to 2016. There were no shares of AFG Common Stock repurchased in 2017 compared to $133 million repurchased in 2016. In addition to its regular quarterly cash dividends, AFG paid special cash dividends of $3.50 per share and $1.00 per share of American Financial Group Common Stock in 2017 and 2016, respectively, which resulted in total cash dividends of $417 million in 2017 compared to $185 million in 2016. Additionally, in 2016, $315 million was used to fund the acquisition of the noncontrolling interest in National Interstate Corporation. 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. Issuances of managed investment entity liabilities exceeded retirements by $146 million in 2017 compared to $693 million in 2016, accounting for a $547 million decrease in net cash provided by financing activities in 2017 compared to 2016. 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 $2.72 billion in 2016 compared to $3.10 billion in 2015, a decrease of $379 million. Annuity receipts exceeded annuity surrenders, benefits, withdrawals and transfers by $2.35 billion in 2016 compared to $2.50 billion in 2015, resulting in a $151 million decrease in net cash provided by financing activities in 2016 compared to 2015. AFG issued $300 million of 3.50% Senior Notes in 2016 and $150 million of 6% Subordinated Debentures in 2015, the net proceeds of which contributed $296 million in 2016 and $145 million in 2015 to net cash provided by financing activities. Redemptions of long-term debt was an $18 million use of cash in 2016 and a $192 million use of cash in 2015. During 2016, AFG repurchased $133 million of its Common Stock compared to $126 million repurchased in 2015, which accounted for a $7 million decrease in net cash provided by financing activities in 2016 compared to 2015. Additionally, during the fourth quarter of 2016, $315 million was used to fund the acquisition of the noncontrolling interest in National Interstate Corporation. Issuances of managed investment entity liabilities exceeded retirements by $693 million in 2016 compared to $890 million in 2015, accounting for a $197 million decrease in net cash provided by financing activities in 2016 compared to 2015.
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 2017.
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.
In November 2016, AFG acquired the 49% of National Interstate Corporation (“NATL”) not previously owned by AFG’s wholly-owned subsidiary, Great American Insurance Company (“GAI”) for $315 million ($32.00 per share) in cash in a merger transaction. In addition, NATL paid a one-time special cash dividend of $0.50 per share to its shareholders immediately prior to the merger closing ($5 million was paid to noncontrolling shareholders). See Note B — “Acquisitions and Sale of Businesses” to the financial statements.
In August 2016, AFG issued $300 million of 3.50% Senior Notes due 2026. AFG used the net proceeds from the offering to fund a portion of the acquisition of NATL mentioned above.

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, 2017, GALIC had $871 million in outstanding advances from the FHLB (included in annuity benefits accumulated), bearing interest at rates ranging from 0.03% to 0.35% over LIBOR (average rate of 1.75% at December 31, 2017). While these advances must be repaid between 2018 and 2020 ($285 million in 2018 and $586 million in 2020), 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, 2017, GALIC estimated that it had additional borrowing capacity of approximately $300 million from the FHLB.
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.

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”). AFG began selling policies with GMIRs below 2% in 2003; almost all new business since late 2010 has been issued with a 1% GMIR. At December 31, 2017, AFG could reduce the average crediting rate on approximately $25 billion of traditional fixed and fixed-indexed annuities without guaranteed withdrawal benefits by approximately 92 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 |  |  |  | 2017 |  | 2016 |  | 2015 |
| 1 — 1.99% |  |  |  | 76% |  | 72% |  | 67% |
| 2 — 2.99% |  |  |  | 5% |  | 6% |  | 7% |
| 3 — 3.99% |  |  |  | 10% |  | 12% |  | 14% |
| 4.00% and above |  |  |  | 9% |  | 10% |  | 12% |
| Annuity benefits accumulated (in millions) |  | $33,316 |  | $29,907 |  | $26,662 |

For statutory accounting purposes, equity securities of non-affiliates and equity call options used in the fixed-indexed annuity business are generally carried at fair value. At December 31, 2017, AFG’s insurance companies owned publicly traded equity securities with a fair value of $1.61 billion and equity call options with a fair value of $701 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,
| 2017 |  | 2016 |  | 2015
Net cash provided by operating activities | $ | 578 |  |  | $ | 555 |  |  | $ | 162 |
Net cash used in investing activities | (63 | ) |  | (560 | ) |  | (33 | )
Net cash provided by (used in) financing activities | (413 | ) |  | 13 |  |  | (232 | )
Net change in cash and cash equivalents | $ | 102 |  |  | $ | 8 |  |  | $ | (103 | )

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 $578 million in 2017 compared to $555 million in 2016 and $162 million in 2015. The $23 million increase in net cash provided by operating activities in 2017 as compared to 2016 was due to lower taxes paid, partially offset by lower dividends received from subsidiaries for those comparable periods. Higher dividends received from subsidiaries in 2016 as compared to 2015 were the primary driver of the $393 million increase in net cash provided by operating activities.
Parent Net Cash 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 $63 million in 2017 compared to $560 million in 2016 and $33 million in 2015. The $63 million in net cash used in investing activities in 2017 and $33 million in 2015 are significantly lower than the $560 million in net cash used in investing activities in 2016 due primarily to capital contributions to a subsidiary to fund the acquisition of the noncontrolling interest in National Interstate Corporation.

Table of Contents
Parent Net Cash Provided by (Used in) Financing Activities Parent company financing activities consist primarily of repurchases of AFG Common Stock, dividends to shareholders, the issuance and retirement of long-term debt and, to a lesser extent, proceeds from employee stock option exercises. 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 $413 million in 2017 compared to net cash provided by financing activities of $13 million in 2016 and net cash used in financing activities of $232 million in 2015. The $426 million increase in cash used in financing activities in 2017 as compared to 2016 reflects higher net redemptions of long-term debt in 2017 and increased dividends (due primarily to special dividends of $3.50 per share in 2017 compared to $1.00 per share in 2016), partially offset by the absence of American Financial Group, Inc. Common Stock repurchases in 2017. The $245 million increase in net cash provided by financing activities in 2016 as compared to 2015 primarily reflects proceeds from additional long-term borrowings.
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) |  | $ | 38,653 |  |  | $ | 2,655 |  |  | $ | 6,552 |  |  | $ | 8,464 |  |  | $ | 20,982 |
Life, accident and health liabilities (a) |  | 1,449 |  |  | 123 |  |  | 209 |  |  | 197 |  |  | 920 |
Property and casualty unpaid losses and loss adjustment expenses (b) |  | 9,678 |  |  | 2,600 |  |  | 2,500 |  |  | 1,100 |  |  | 3,478 |
Long-term debt, including interest |  | 2,922 |  |  | 60 |  |  | 120 |  |  | 120 |  |  | 2,622 |
Operating leases |  | 346 |  |  | 63 |  |  | 107 |  |  | 76 |  |  | 100 |
Total |  | $ | 53,048 |  |  | $ | 5,501 |  |  | $ | 9,488 |  |  | $ | 9,957 |  |  | $ | 28,102 |

(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 $33.32 billion for annuity benefits accumulated and $658 million for life, accident and health reserves included in AFG’s Balance Sheet as of December 31, 2017. Based on the same assumptions, AFG projects reinsurance recoveries related to life, accident and health reserves totaling $708 million as follows: Within 1 year — $68 million; 2-3 years — $124 million; 4-5 years — $96 million; and thereafter — $420 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 $2.96 billion as follows: Within 1 year — $800 million; 2-3 years — $800 million; 4-5 years — $300 million; and thereafter — $1.06 billion. Actual payments and their timing could differ significantly from these estimates.

AFG has no material contractual purchase obligations or other long-term liabilities at December 31, 2017.
Off-Balance Sheet Arrangements See Note P — “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, 2017, contained $38.38 billion in fixed maturity securities and $1.60 billion in equity 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. In addition, $348 million in fixed maturities and $62 million in equity securities were classified as trading with changes in unrealized holding gains or losses included in net investment income.
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 and equity 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, noncontrolling interests 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, 2017, the average life of AFG’s fixed maturities was about 6-1/2 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 mortgage-backed securities (“MBS”), which comprise approximately 11% of AFG’s fixed maturities, prices for each security are generally obtained from both pricing services and broker quotes. For the remainder of AFG’s fixed maturity portfolio, approximately 76% are priced using pricing services and the balance is 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 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, 2017 (dollars in millions). Effects of increases or decreases from the 100 basis points illustrated would be approximately proportional.

Fair value of fixed maturity portfolio | $ | 38,727 |
Percentage impact on fair value of 100 bps increase in interest rates | (5.0 | %)
Pretax impact on fair value of fixed maturity portfolio | $ | (1,936 | )
Offsetting adjustments to deferred policy acquisition costs and other balance sheet amounts | 750 |
Estimated pretax impact on accumulated other comprehensive income | (1,186 | )
Deferred income tax | 249 |
Estimated after-tax impact on accumulated other comprehensive income | $ | (937 | )

Approximately 90% of the fixed maturities held by AFG at December 31, 2017, 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 due to the fact that, 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. Although interest rates have been low in recent years, tighter lending standards have resulted in fewer buyers being able to refinance the mortgages underlying much of AFG’s non-agency residential MBS portfolio.

Summarized information for AFG’s MBS (including those classified as trading) at December 31, 2017, 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 5-1/2 years, respectively.

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, 2017, 97% (based on statutory carrying value of $3.75 billion) of AFG’s MBS had an NAIC designation of 1.
Municipal bonds represented approximately 18% of AFG’s fixed maturity portfolio at December 31, 2017. 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, 2017, approximately 77% of the municipal bond portfolio was held in revenue bonds, with the remaining 23% held in general obligation bonds. AFG does not own general obligation bonds issued by Puerto Rico.

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,

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 dividend 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.

36

Table of Contents
Based on its analysis of the factors listed above, 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, 2017. Although AFG has the ability to continue holding its 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 with regard to 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.”
As discussed in Note A — “Accounting Policies — Investments” to the financial statements, effective January 1, 2018, all equity securities currently classified as “available for sale” will be required to be carried at fair value through net earnings instead of accumulated other comprehensive income and will therefore no longer be evaluated for other-than-temporary impairment.
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 O — “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.

While current factors and reasonably likely changes in variable factors are considered in estimating the liability for unpaid losses, 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 4%) 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 | $ | 37 |
Workers’ compensation | 75 |
Other liability — claims made | 10 |
Commercial auto/truck liability/medical | 10 |

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, 2017, reserves (net of reinsurance) developed at the same rate as the average development of the most recent five years.

The following discussion describes key assumptions and important variables that affect the estimate of the reserve for loss and loss adjustment expenses 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 $37 million in 2017 related to its other liability — occurrence coverage due to continued severity increases in New York contractor claims, as well as increased claim severity across other excess and umbrella liability coverages and general liability coverages. AFG recorded adverse prior year reserve development of $61 million in 2016 due primarily to increased severity in New York contractor claims. AFG recorded favorable prior year reserve development of $7 million in 2015 as both the frequency and severity of claims in excess and umbrella liability coverages were lower than previously projected.
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

39

Table of Contents

• | Pace and intensity of employee rehabilitation

• | Changes in the use of pharmaceutical drugs

• | Changes in longevity trends for permanently injured workers

Approximately 25% and 24% of AFG’s workers’ compensation reserves at December 31, 2017 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.
AFG recorded favorable prior year reserve development of $79 million in 2017 related to its workers’ compensation coverage due to lower than anticipated claim severity and improving claim closure rates, particularly in the southeastern United States and California. AFG recorded favorable prior year reserve development of $85 million in 2016 due to lower than anticipated claim severity and improving claim closure rates. AFG recorded favorable prior year reserve development of $45 million in 2015 due to lower than anticipated claim severity across all regions of the country.
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 consistently decreased from its peak in 2010, offsetting increased claim severity.
AFG recorded favorable prior year reserve development of $5 million in 2017, $24 million in 2016 and $12 million in 2015 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 adverse prior year reserve development of $2 million in 2017, $28 million in 2016 and $20 million in 2015 for this line of business. Claim severity trends had been significantly higher than expected beginning with accident years 2010, but have more recently stabilized.
Reserves of Foreign Operations
Approximately $631 million of the $901 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. Neon writes bloodstock and livestock, cargo, cyber, financial lines, marine and energy liability, marine hull and war, mergers and acquisitions, personal accident and health, political and trade risk, professional indemnity, property and terrorism and political violence insurance.
During the second quarter of 2016, Neon completed a strategic review of its business under a new leadership team. As part of its strategic review, Neon sold and/or exited certain historical lines of business including its medical malpractice and general

Table of Contents
liability classes. As a result of Neon’s claims review of its exited lines of business, AFG recorded a charge of approximately $65 million, including $57 million to increase loss reserves (adverse development) primarily related to Neon’s medical malpractice and general liability lines.
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. Going forward, 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

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 the exited lines of business discussed above. In addition to the prior year reserve development related to the reinsurance to close transaction and 2016 Neon exited lines charge, Neon recorded favorable prior year reserve development of $29 million in 2017 compared to adverse prior year reserve development of $21 million in 2016 and $44 million in 2015. The favorable reserve development in 2017 outside of the reinsurance to close transaction related to the retained loss reserves across all of Neon’s ongoing lines of business, particularly property lines. The adverse reserve development in 2016 outside of the exited lines charge was attributable to reserve strengthening in several lines of business, including political risk and personal accident. The adverse reserve development in 2015 was attributable to reserve strengthening in several lines of business, primarily Dutch hospital medical malpractice, Australian and other general liability and personal accident insurance.
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 with investment grade S&P ratings 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 O — “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.

|  | 2017 |  | 2016 |  | 2015
Before reinsurance (gross) |  | 98.9 | % |  | 92.5 | % |  | 92.8 | %
Effect of reinsurance |  | (4.2 | %) |  | 2.0 | % |  | 1.9 | %
Actual (net of reinsurance) |  | 94.7 | % |  | 94.5 | % |  | 94.7 | %

Outside of its property and casualty operations, AFG also has reinsurance recoverables totaling $312 million, including $263 million related to the run-off life business. These recoverables include $223 million directly or indirectly from Hannover Life Reassurance Company of America (rated A+ by A.M. Best).

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,
|  | 2017 |  | 2016
Asbestos |  | $ | 238 |  |  | $ | 198 |
Environmental |  | 165 |  |  | 139 |
A&E reserves, net of reinsurance recoverable |  | 403 |  |  | 337 |
Reinsurance recoverable, net of allowance |  | 125 |  |  | 106 |
Gross A&E reserves |  | $ | 528 |  |  | $ | 443 |

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 recent years, a number of asbestos claims are being presented as “non-products” claims, such as those by installers of asbestos products and by property 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 potentially 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. AFG, along with other insurers, is and will be subject to such non-products claims. It is difficult to predict whether insureds will be successful in asserting claims under non-products coverage or whether AFG and other insurers will be successful in asserting additional defenses. Therefore, the future impact of such efforts is uncertain.
Approximately 42% 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 for the periods 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. The casualty insurance industry is engaged in extensive litigation over these coverage and liability issues as the volume and severity of claims against asbestos defendants continue to increase. 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.

Table of Contents
The following factors could impact AFG’s reserves and payments:

• | There is a growing 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 recent 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 $35 million.
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.

|  | 2017 |  | 2016 |  | 2015
Number of policyholders with no indemnity payments: |  |  |  |  |  |
Asbestos |  | 81 |  |  | 87 |  |  | 122 |
Environmental |  | 101 |  |  | 107 |  |  | 112 |
|  | 182 |  |  | 194 |  |  | 234 |
Number of policyholders with indemnity payments: |  |  |  |  |  |
Asbestos |  | 74 |  |  | 66 |  |  | 50 |
Environmental |  | 31 |  |  | 28 |  |  | 25 |
|  | 105 |  |  | 94 |  |  | 75 |
Total |  | 287 |  |  | 288 |  |  | 309 |

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

|  | 2017 |  | 2016 |  | 2015
Asbestos |  | $ | 11 |  |  | $ | 12 |  |  | $ | 16 |
Environmental |  | 12 |  |  | 14 |  |  | 13 |
Total |  | $ | 23 |  |  | $ | 26 |  |  | $ | 29 |

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, 2017, 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, 2016) as detailed in the following table:

| Property and Casualty Insurance Reserves
| Three-Year Survival Ratio (% Times Paid Losses)
| Asbestos |  | Environmental |  | Total A&E
AFG (12/31/2017) | 18.6 |  |  | 12.8 |  |  | 15.7 |
Industry (12/31/2016) | 6.7 |  |  | 8.0 |  |  | 6.9 |

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, generally every two years, with an in-depth internal review during the intervening years.
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
43

Table of Contents
its environmental reserves by $36 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 insurance segment’s asbestos reserve increases in recent years. AFG is seeing modestly increasing estimates for indemnity and defense compared to prior studies. Overall, the rate of new asbestos cases received is down modestly, however, increasing life expectancies in the U.S. 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, which has resulted in an increase in AFG’s provision for future asbestos claims.
The increase in property and casualty environmental reserves was primarily associated with updated estimates of site investigation costs with respect to existing sites and newly identified sites. AFG is seeing increased legal defense costs in environmental claims generally, as well as a number of claims and sites where the estimated investigation and remediation costs have increased. Certain individual claims are taking a longer time to settle than originally estimated, causing AFG to increase its reserves to reflect related increased costs. As in past years, there were no new or emerging broad industry trends that were identified in this study.
An in-depth internal review of AFG’s A&E reserves was completed in the third quarter of 2016 by AFG’s internal A&E claims specialists and actuaries in consultation with specialty outside counsel and an outside consultant. As a result of the review, AFG’s property and casualty insurance segment recorded a $36 million pretax special charge to increase its asbestos reserves by $5 million (net of reinsurance) and its environmental reserves by $31 million (net of reinsurance). The increase in property and casualty asbestos reserves was due primarily to increased estimates for indemnity and defense costs. The increase in property and casualty environmental reserves was attributed primarily to increased defense costs and a number of claims and sites where the estimated investigation and remediation costs have increased.
As a result of the comprehensive external study completed in the third quarter of 2015, AFG’s property and casualty insurance segment recorded a $67 million pretax special charge to increase its asbestos reserves by $25 million (net of reinsurance) and its environmental reserves by $42 million (net of reinsurance). The increase in property and casualty asbestos reserves was attributed to increased estimates for indemnity and defense costs. The increase in property and casualty environmental reserves was attributed primarily to increased defense costs and a number of claims where the estimated costs of remediation 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 $24 million in 2017, $5 million in 2016 and $12 million in 2015. 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 $90 million at December 31, 2017. For a discussion of the uncertainties in determining the ultimate liability, see Note M — “Contingencies” to the financial statements.
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 the future 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. 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 (1,600 policies) with approximately $39 million of reserves at December 31, 2017. 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.

Table of Contents
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. 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.

Net earnings attributable to shareholders increased $297 million for the full-year of 2016 compared to the same period in 2015 due primarily to the 2016 tax benefits related to the National Interstate merger and Neon restructuring, lower special A&E charges recorded in 2016 compared to 2015, net realized gains on securities in 2016 compared to net realized losses on securities in 2015, the estimated loss on the sale of the subsidiaries containing substantially all of AFG’s run-off long-term care insurance business that was recorded in the first quarter of 2015 and higher core net operating earnings, partially offset by a charge related to the exit of certain lines of business within Neon, and lower gains on the sale of real estate in 2016 compared to 2015. Core net operating earnings increased $48 million in 2016 compared to 2015 reflecting higher underwriting profit and net investment income in the ongoing property and casualty insurance operations and higher earnings in the annuity segment, partially offset by lower profitability in the run-off long-term care and life segment and higher holding company expenses.

RESULTS OF OPERATIONS — QUARTERS ENDED DECEMBER 31, 2017 AND 2016
Segmented Statement of Earnings AFG reports its business as four segments: (i) Property and casualty insurance (“P&C”), (ii) Annuity, (iii) Run-off long-term care and life and (iv) Other, which includes 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, 2017 and 2016 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 loss adjustment expenses, and commissions and other underwriting expenses to premiums. A combined ratio under 100% indicates an underwriting profit. The combined ratio does not reflect net investment income, other income, other expenses or federal income taxes.
AFG’s property and casualty insurance operations contributed $251 million in GAAP pretax earnings in the fourth quarter of 2017 compared to $182 million in the fourth quarter of 2016, an increase of $69 million (38%). Property and casualty core pretax earnings were $233 million in the fourth quarter of 2017 compared to $182 million in the fourth quarter of 2016, an increase of $51 million (28%). The increase in GAAP and core pretax earnings reflects improved underwriting results in the Property and transportation and Specialty casualty insurance sub-segments and lower other expenses. The increase in GAAP

pretax earnings also reflects favorable development in the fourth quarter of 2017 in the Neon exited lines in connection with a reinsurance to close transaction.

Combined ratio | 86.0 | % |  | 90.4 | % |  | (4.4 | %)

AFG’s statutory combined ratio has been better than the U.S. industry average for 30 of the last 32 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.

The $130 million increase in gross written premiums in the fourth quarter of 2017 compared to the fourth quarter of 2016 reflects growth in each of the Specialty property and casualty insurance sub-segments. Overall average renewal rates increased approximately 1% in the fourth quarter of 2017.
Property and transportation Gross written premiums increased $49 million (8%) in the fourth quarter of 2017 compared to the fourth quarter of 2016. This increase was due primarily to higher year-over-year gross written premiums in the crop business, as well as higher gross written premiums in the property and inland marine and Singapore operations. This growth was partially offset by lower gross written premiums resulting from an exit from the customs bond business, which was part of the ocean marine operations. Average renewal rates increased approximately 3% for this group in the fourth quarter of 2017. Reinsurance premiums ceded as a percentage of gross written premiums are comparable between periods.
Specialty casualty Gross written premiums increased $53 million (8%) in the fourth quarter of 2017 compared to the fourth quarter of 2016. Higher gross written premiums at Neon, resulting from the growth of its portfolio in targeted classes of business, higher gross written premiums in the workers’ compensation businesses, primarily the result of rate increases in Florida, and growth in the excess and surplus lines businesses all contributed to the year-over-year growth. Average renewal rates for this group increased approximately 1% in the fourth quarter of 2017. Reinsurance premiums ceded as a percentage of gross written premiums are comparable between periods.
Specialty financial Gross written premiums increased $28 million (16%) in the fourth quarter of 2017 compared to the fourth quarter of 2016, due primarily to higher premiums in the lending and leasing businesses. Average renewal rates for this group were flat in the fourth quarter of 2017. Reinsurance premiums ceded as a percentage of gross written premiums increased 11 percentage points for the fourth quarter of 2017 compared to the fourth quarter of 2016 reflecting higher cessions in the lending and leasing businesses.
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.

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:

The Specialty property and casualty insurance operations generated an underwriting profit of $156 million for the fourth quarter of 2017 compared to $110 million in the fourth quarter of 2016, an increase of $46 million (42%). The higher underwriting profit in the fourth quarter of 2017 reflects improved underwriting results in the Property and transportation and Specialty casualty sub-segments. Overall catastrophe losses were $8 million (0.6 points on the combined ratio) and related net reinstatement premiums paid were $4 million in the fourth quarter of 2017 compared to catastrophe losses of $12 million (1.1 points) in the fourth quarter of 2016. Losses related to third quarter catastrophes, specifically Hurricanes Harvey, Irma and Maria, and two earthquakes in Mexico, developed favorably by $25 million during the fourth quarter of 2017 across all property and casualty sub-segments.
Property and transportation Underwriting profit for this group was $84 million for the fourth quarter of 2017 compared to $75 million in the fourth quarter of 2016, an increase of $9 million (12%) reflecting higher underwriting profit in the transportation businesses, partially offset by lower year-over-year underwriting profits in the agricultural operations. The crop insurance operations reported strong underwriting profitability during the fourth quarter of 2017, albeit at lower levels than in the 2016 fourth quarter. Catastrophe losses had a favorable impact of $3 million (0.6 points on the combined ratio) for the fourth quarter of 2017 compared to a $6 million loss (1.2 points) for the fourth quarter of 2016. Catastrophe losses for the fourth quarter of 2017 include the impact of the favorable reserve development on third quarter catastrophes discussed above.
Specialty casualty Underwriting profit for this group was $58 million for the fourth quarter of 2017 compared to $13 million in the fourth quarter of 2016, an increase of $45 million (346%). This increase is due primarily to favorable reserve

development within Neon, most significantly the portion of the 2015 and prior years reinsurance to close transaction attributed to ongoing lines of business, and higher underwriting profit in the workers’ compensation and excess and surplus lines businesses. These improved results were partially offset by lower underwriting profits in the targeted markets operations. Catastrophe losses were $14 million (2.5 points on the combined ratio) and related net reinstatement premiums paid were $4 million for the fourth quarter of 2017 compared to catastrophe losses of $4 million (0.8 points) for the fourth quarter of 2016. Catastrophe losses for the fourth quarter of 2017 include the impact of the favorable reserve development on third quarter catastrophes discussed above.
Specialty financial Underwriting profit for this group was $19 million for the fourth quarter of 2017 compared to $20 million in the fourth quarter of 2016, a decrease of $1 million (5%) reflecting underwriting profit in all businesses in this group. Catastrophe losses had a favorable impact of $5 million (3.7 points on the combined ratio) for the fourth quarter of 2017 compared to a loss of $2 million (1.7 points) for the fourth quarter of 2016. Catastrophe losses for the fourth quarter of 2017 include the impact of the favorable reserve development on third quarter catastrophes discussed above.
Other specialty This group reported an underwriting loss of $5 million for the fourth quarter of 2017 compared to underwriting profit of $2 million in the fourth quarter of 2016, a decrease of $7 million (350%). The decrease is due primarily to an $8 million charge to adjust the deferred gain on the retroactive reinsurance transaction entered into in connection with the sale of businesses in 1998.

Table of Contents
Property and transportation Net favorable reserve development of $4 million in the fourth quarter of 2017 reflects lower than expected losses in the crop business and lower than expected claim severity in the property and inland marine and trucking businesses, partially offset by higher than expected claim severity and frequency in the ocean marine business. Net adverse reserve development of $13 million in the fourth quarter of 2016 reflects reserve strengthening at National Interstate and higher than expected claim severity in the ocean marine business.
Specialty casualty Net favorable reserve development of $52 million in the fourth quarter of 2017 reflects favorable reserve 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, partially offset by higher than anticipated claim severity in the targeted markets businesses and higher than anticipated severity in New York contractor claims. Net adverse reserve development of $3 million in the fourth quarter of 2016 reflects higher than anticipated severity in New York contractor claims, adverse reserve development at Neon and higher than anticipated claim severity in the targeted programs business, partially offset by lower than anticipated claim frequency and severity in the workers’ compensation businesses.
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 development of $42 million, of which $24 million related to its ongoing lines of business (included in Specialty casualty) and $18 million related to the exited lines of business (discussed below and included in Neon exited lines charge).
Specialty financial Net adverse reserve development of $1 million in the fourth quarter of 2017 reflects higher than expected claim severity in the financial institutions business, partially offset by lower than anticipated claim frequency and severity in the surety business. Net favorable reserve development of $6 million in the fourth quarter of 2016 reflects lower than expected claim frequency in the financial institutions business and lower than anticipated claim severity in the fidelity 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 in the fourth quarter of 2017 reflecting an $8 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 insurance.
Neon exited lines charge During the second quarter of 2016, AFG’s specialist Lloyd’s market insurer completed a strategic review of its business under a new leadership team and re-launched as Neon Underwriting Ltd. As part of its strategic review, Neon sold and/or exited certain historical lines of business including its UK and international medical malpractice and general liability classes. As a result of Neon’s claims review of its exited lines of business, AFG recorded a charge of approximately $65 million including $57 million to increase loss reserves primarily related to its medical malpractice and general liability lines. Consistent with the treatment of other items that are not indicative of AFG’s ongoing operations (both favorable and unfavorable), the 2016 charge was treated as non-core because it resulted from a special strategic review of lines of business that Neon no longer writes. Similarly, the $18 million in favorable development related to the Neon exited lines recorded in connection with the December 2017 reinsurance to close transaction (discussed above under Specialty casualty) was treated as non-core.
Aggregate Aggregate net prior accident years reserve development for AFG’s property and casualty insurance segment for the fourth quarter of 2017 includes the favorable development on the Neon exited lines discussed above and adverse reserve development of $1 million related to business outside of 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. Based on data available at December 31, 2017, 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:

|  |  | Impact of modeled loss on AFG’s |
| Industry Model |  | Shareholders’ Equity |
| 100-year event |  | Less than 1% |
| 250-year event |  | Less than 2% |
| 500-year event |  | Less than 4% |

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 $100 million and a separate $15 million per occurrence retention for Neon for losses up to $200 million ($225 million for U.S. catastrophe events). 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 $100 million of traditional catastrophe reinsurance through a catastrophe bond.
Catastrophe losses of $8 million in the fourth quarter of 2017 resulted primarily from wildfires in California, partially offset by favorable development related to third quarter 2017 catastrophe losses, specifically Hurricanes Harvey, Irma and Maria, and two earthquakes in Mexico. Catastrophe losses of $12 million in the fourth quarter of 2016 resulted primarily from Hurricane Matthew.
Commissions and Other Underwriting Expenses
AFG’s property and casualty commissions and other underwriting expenses (“U/W Exp”) were $336 million in the fourth quarter of 2017 compared to $305 million for the fourth quarter of 2016, an increase of $31 million (10%). AFG’s underwriting expense ratio, calculated as commissions and other underwriting expenses divided by net premiums earned, was 27.5% for the fourth quarter of 2017 compared to 26.7% for the fourth quarter of 2016, an increase of 0.8 percentage points. Detail of AFG’s property and casualty commissions and other underwriting expenses and underwriting expense ratios is shown below (dollars in millions):

Property and Casualty Net Investment Income
Net investment income in AFG’s property and casualty insurance operations was $86 million in the fourth quarter of 2017 compared to $85 million in the fourth quarter of 2016, an increase of $1 million (1%). In recent years, yields available in the financial markets on fixed maturity securities have generally declined, placing downward pressure on AFG’s investment portfolio yield. 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, |  |  |  |

The increase in average invested assets and net investment income in the property and casualty insurance segment for the fourth quarter of 2017 as compared to the fourth quarter of 2016 is due primarily to 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 3.42% for the fourth quarter of 2017 compared to 3.48% for the fourth quarter of 2016, a decrease of 0.06 percentage points, reflecting the impact of lower yields available in the financial markets and lower income from equity in the earnings of limited partnerships and similar investments.
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 $8 million for the fourth quarter of 2017 compared to $13 million for the fourth quarter of 2016, a decrease of $5 million (38%).

Annuity Segment — Results of Operations
AFG’s annuity operations contributed $97 million in pretax earnings in the fourth quarter of 2017 compared to $132 million in the fourth quarter of 2016, a decrease of $35 million (27%). AFG’s annuity segment results for the fourth quarter of 2017 as compared to the fourth quarter of 2016 reflect the unfavorable impact of lower than expected interest rates on the fair value accounting for fixed-indexed annuities (“FIAs”) in the 2017 quarter compared to the favorable impact of higher than anticipated interest rates in the 2016 quarter, the impact of lower investment yields due to the run-off of higher yielding investments and higher general and administrative expenses, partially offset by a 10% increase in average annuity investments (at amortized cost). Both periods reflect the positive impact of strong stock market performance on fair value accounting for FIAs and exceptionally strong investment income. AFG’s periodic detailed review (“unlocking”) of the major actuarial assumptions underlying its annuity operations resulted in a net annuity charge of $3 million in the fourth quarter of 2017 compared to a net annuity expense reduction of $1 million in the fourth quarter of 2016.

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.

Annuity Net Investment Income
Net investment income for the fourth quarter of 2017 was $376 million compared to $346 million for the fourth quarter of 2016, an increas e of $30 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 fixed annuity operations, calculated as net investment income divided by average investment balances (at amortized cost), decreased by 0.10 percentage points to 4.62% from 4.72% in the fourth quarter of 2017 compared to the fourth quarter of 2016. This decrease in net investment yield reflects (i) the investment of new premium dollars at lower yields as compared to the existing investment portfolio and (ii) the impact of the reinvestment of proceeds from maturity and redemption of higher yielding investments at the lower yields available in the financial markets, partially offset by higher equity in the earnings of limited partnerships and similar investments and favorable investment income resulting from early redemptions and other items. During the full year of 2017, $4.9 billion in annuity segment investments with an average yield of 5.14% were redeemed or sold while the investments purchased during 2017 (with new premium dollars and the redemption/sale proceeds) had an average yield at purchase of 3.94%.
Annuity Interest Credited — Fixed
Interest credited — fixed for the fourth quarter of 2017 was $164 million compared to $148 million for the fourth quarter of 2016, an increase of $16 million (11%). The impact of growth in the annuity business was partially offset by lower interest crediting rates on new premiums as compared to the crediting rates on policyholder funds surrendered or withdrawn. The average interest rate credited to policyholders, calculated as interest credited divided by average fixed annuity benefits accumulated, decreased 0.02 percentage points to 2.00% in the fourth quarter of 2017 from 2.02% in the fourth quarter of 2016.
Annuity Net Interest Spread
AFG’s net interest spread decreased 0.08 percentage points to 2.62% from 2.70% in the fourth quarter of 2017 compared to the same period in 2016 due primarily to the impact of lower fixed maturity investment yields, partially offset by the impact of lower crediting rates. 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.
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 $7 million in the fourth quarter of 2017 compared to $13 million in the fourth quarter of 2016, a decrease of $6 million (46%). Excluding the impact of unlocking charges of $3 million in the fourth quarter of 2017 and $1 million in the fourth quarter of 2016 related to unearned revenue, annuity policy charges and other miscellaneous income were $10 million in the fourth quarter of 2017 compared to $14 million in the fourth quarter of 2016, a decrease of $4 million (29%). The fourth quarter of 2016 includes $2 million from the sale of real estate. 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 0.05 percentage points to 0.10% in the fourth quarter of 2017 from 0.15% in the fourth quarter of 2016.

Other Annuity Benefits, Net of Guaranteed Withdrawal Benefit Fees
Other annuity benefits, net of guaranteed withdrawal benefit fees (excluding the impact of unlocking) for the fourth quarter of 2017 were $18 million compared to $28 million for the fourth quarter of 2016, a decrease of $10 million (36%). As a percentage of average fixed annuity benefits accumulated, these net expenses decreased 0.17 percentage points to 0.21% from 0.38% in the fourth quarter of 2017 compared to the fourth quarter of 2016. 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,
| 2017 |  | 2016
Change in expected death and annuitization reserve | $ | 5 |  |  | $ | 4 |
Amortization of sales inducements | 5 |  |  | 7 |
Change in guaranteed withdrawal benefit reserve | 16 |  |  | 20 |
Change in other benefit reserves | 9 |  |  | 11 |
Other annuity benefits | 35 |  |  | 42 |
Offset guaranteed withdrawal benefit fees | (17 | ) |  | (14 | )
Other annuity benefits, net | $ | 18 |  |  | $ | 28 |

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. 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.
The $10 million decrease in other annuity benefits, net of guaranteed withdrawal benefit fees in the fourth quarter of 2017 compared to the fourth quarter of 2016 reflects the impact of the increase in the fair value of the FIA embedded derivative reserve resulting from lower than anticipated interest rates on the guaranteed withdrawal benefits.
See “Annuity Unlocking” below for a discussion of the impact that the periodic review of actuarial assumptions had on annuity benefits expense.
Annuity Acquisition Expenses
Excluding the impact of unlocking charges (expense reductions) discussed under “Annuity Unlocking” below, AFG’s amortization of DPAC and commission expenses as a percentage of average fixed annuity benefits accumulated was 0.60% for the fourth quarter of 2017 compared to 1.06% for the fourth quarter of 2016 and has generally ranged between 0.75% and 0.85%. Variances from the general range relate primarily to the impact of (i) material changes in interest rates or the stock market on AFG’s fixed-indexed annuity business, and (ii) differences in actual experience from actuarially projected estimates and assumptions. For example, the negative impact of the lower than anticipated interest rates during the fourth quarter of 2017 on the fair value of derivatives related to fixed-indexed annuities (discussed below) resulted in a partially offsetting deceleration in the amortization of DPAC. In contrast, the positive impact of significantly higher than anticipated interest rates in the fourth quarter of 2016 on the fair value of derivatives related to fixed-indexed annuities resulted in a partially offsetting acceleration in the amortization of DPAC.
The table below illustrates the estimated impact of fair value accounting for derivatives related to fixed-indexed annuities on annuity acquisition expenses as a percentage of average fixed annuity benefits accumulated:

| Three months ended December 31,
| 2017 |  | 2016

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”).
Annuity Other Expenses
Annuity other expenses were $31 million for the fourth quarter of 2017 compared to $27 million for the fourth quarter of 2016, an increase of $4 million (15%). Annuity other expenses represent primarily general and administrative expenses, as well as selling and issuance expenses that are not deferred. The increase in annuity other expenses reflects primarily growth in the business and an increase in the number of sales personnel focused on new initiatives and increased market share within existing financial institutions and retail marketing organizations in the fourth quarter of 2017 compared to the fourth quarter of 2016. As a percentage of average fixed annuity benefits accumulated, these expenses increased 0.02 percentage points to 0.37% from 0.35% for the fourth quarter of 2017 as compared to the fourth quarter of 2016.
Change in Fair Value of Derivatives Related to Fixed-Indexed Annuities
AFG’s fixed-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 of call options on the appropriate index. AFG’s strategy is designed so that the change in the fair value of the call option assets will generally offset the economic change in the liabilities from the index participation. Both the index-based component of the annuities (an embedded derivative) and the related call 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 index-based component (embedded derivative) of AFG’s annuity benefits accumulated, see Note D — “Fair Value Measurements” to the financial statements. In addition, the change in the fair value of the embedded derivative includes interest accreted on the FIA embedded derivative reserve of $5 million in the fourth quarter of 2017 and $2 million in the fourth quarter of 2016 (before the related impact on the amortization of deferred sales inducements and deferred policy acquisition costs).
Excluding the impact of unlocking charges, the net change in fair value of derivatives related to fixed-indexed annuities increased annuity benefits by $22 million in the fourth quarter of 2017 and decreased annuity benefits by $54 million in the fourth quarter of 2016. The $22 million increase in annuity benefits in the fourth quarter of 2017 reflects the negative impact of lower than anticipated interest rates on the fair value of these derivatives, partially offset by the positive impact of strong stock market performance. The $54 million decrease in annuity benefits in the fourth quarter of 2016 reflects the positive impact of significantly higher than anticipated interest rates and strong stock market performance on the fair value of these derivatives. As a percentage of average fixed annuity benefits accumulated, this net expense decreased 1.00 percentage points to 0.27% in the fourth quarter of 2017 from a net expense reduction of 0.73% in the fourth quarter of 2016.
Fluctuations in interest rates and the stock market, among other factors, can cause volatility in the periodic measurement of fair value of the embedded derivative that management believes can be inconsistent with the long-term economics of these products. The table below illustrates the impact of fair value accounting for derivatives related to fixed-indexed annuities on the annuity segment’s earnings before income taxes (dollars in millions):

| Three months ended December 31, |  |
| 2017 |  | 2016 |  | % Change
Earnings before income taxes — before change in fair value of derivatives related to FIAs | $ | 108 |  |  | $ | 103 |  |  | 5 | %
Change in fair value of derivatives related to FIAs | (22 | ) |  | 54 |  |  | (141 | %)
Related impact on amortization of DPAC (*) | 11 |  |  | (25 | ) |  | (144 | %)
Earnings before income taxes | $ | 97 |  |  | $ | 132 |  |  | (27 | %)

(*) | An estimate of the related acceleration/deceleration of amortization of deferred sales inducements and deferred policy acquisition costs.

As illustrated in the table above, the change in fair value of derivatives related to fixed-indexed annuities, including the related impact on amortization of DPAC, decreased the annuity segment’s earnings before income taxes by $11 million in the fourth quarter of 2017 and increased the annuity segment’s earnings before income taxes by $29 million in the fourth quarter of 2016.
See “Annuity Unlocking” below for a discussion of the impact that the periodic review of actuarial assumptions had on the change in the fair value of the embedded derivative liability.

Annuity Net Spread Earned on Fixed Annuities
AFG’s net spread earned on fixed annuities decreased 0.61 percentage points to 1.21% from 1.82% in the fourth quarter of 2017 compared to the same period in 2016 due primarily to the net impact of changes in the fair value of derivatives and related DPAC amortization offset discussed above.
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, 2017 and 2016 (in millions):

| Three months ended December 31,

Statutory Annuity Premiums
AFG’s annuity operations generated statutory premiums of $909 million in the fourth quarter of 2017 compared to $1.11 billion in the fourth quarter of 2016, a decrease of $202 million (18%). The following table summarizes AFG’s annuity sales (dollars in millions):

| Three months ended December 31, |  |
2017 |  | 2016 |  | % Change
Financial institutions single premium annuities — indexed | $ | 364 |  |  | $ | 474 |  |  | (23 | %)
Financial institutions single premium annuities — fixed | 63 |  |  | 152 |  |  | (59 | %)
Retail single premium annuities — indexed | 413 |  |  | 415 |  |  | — | %
Retail single premium annuities — fixed | 22 |  |  | 22 |  |  | — | %
Education market — fixed and indexed annuities | 41 |  |  | 40 |  |  | 3 | %
Total fixed annuity premiums | 903 |  |  | 1,103 |  |  | (18 | %)
Variable annuities | 6 |  |  | 8 |  |  | (25 | %)
Total annuity premiums | $ | 909 |  |  | $ | 1,111 |  |  | (18 | %)

Management attributes the 18% decrease in annuity premiums to AFG’s adherence to pricing discipline in a relatively low and decreasing interest rate environment during the year.
AFG continues to implement product and process changes needed to comply with the Department of Labor (“DOL”) Fiduciary Rule. Although the DOL Fiduciary Rule became effective on June 9, 2017, the DOL delayed certain requirements until
68

Table of Contents
January 1, 2018. As a result, insurance-only agents were able to continue selling fixed-indexed annuities through the end of 2017, provided the agent acted in the customer’s best interest, made no misleading statements and received only reasonable compensation. The DOL recently released a proposal to delay full implementation until July 1, 2019. There is uncertainty as to whether the rule will take effect in its current form on that date.
AFG believes the biggest impact of the rule will be on insurance-only licensed agents whose qualified sales represented approximately 10% of its fourth quarter 2017 annuity premiums. AFG’s management continues to believe that full implementation is likely to cause some short-term disruption in annuity premiums. Nonetheless, management does not believe the new rule will have a material impact on AFG’s results of operations.
Annuity Unlocking
In the fourth quarters of 2017 and 2016, AFG conducted a detailed review (“unlocking”) of the major actuarial assumptions underlying its annuity operations. As a result of these reviews, AFG recorded a net charge related to its annuity business of $3 million in 2017 and a net expense reduction of $1 million in 2016, which impacted AFG’s financial statements as follows (in millions):

|  | Three months ended December 31,
|  | 2017 |  | 2016
Policy charges and other miscellaneous income: |  |  |  |
Unearned revenue |  | $ | (3 | ) |  | $ | (1 | )
Total revenues |  | (3 | ) |  | (1 | )
Annuity benefits: |  |  |  |
Fixed-indexed annuity embedded derivative |  | 25 |  |  | 17 |
Sales inducements |  | (6 | ) |  | (4 | )
Other reserves |  | 16 |  |  | 10 |
Total annuity benefits |  | 35 |  |  | 23 |
Annuity and supplemental insurance acquisition expenses: |  |  |  |
Deferred policy acquisition costs |  | (35 | ) |  | (25 | )
Total costs and expenses |  | — |  |  | (2 | )
Net expense reduction (charge) |  | $ | (3 | ) |  | $ | 1 |

The net charge from unlocking annuity assumptions in the fourth quarter of 2017 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. Reinvestment rate assumptions are based primarily on 7-year and 10-year corporate bond yields. For the 2017 unlocking, AFG assumed a net reinvestment rate (net of default and expense assumptions) of 3.99% in 2018, grading up ratably to an ultimate net reinvestment rate of 5.55% in 2023 and beyond.
The table below compares the reinvestment rate assumed on assets purchased to directly support “fixed annuity benefits accumulated” in AFG’s fourth quarter unlockings for the next calendar year to the actual reinvestment rate achieved in that period (both net of investment expenses):

|  | First |  |  |  |
Unlocking |  | Investment |  | Reinvestment Rate
Year |  | Period |  | Assumed (*) |  | Achieved
2014 |  | 2015 |  | 3.75 | % |  | 4.27 | %
2015 |  | 2016 |  | 4.05 | % |  | 4.27 | %
2016 |  | 2017 |  | 4.42 | % |  | 3.95 | %
2017 |  | 2018 |  | 4.17 | % |  | n/a |

(*) | Assumed reinvestment rates exclude default rates of 0.18% in each period.

Management believes that these results over the last several years demonstrate that AFG’s investment rate assumptions are reasonable and prudently conservative. During 2017, long-term interest rates were lower than anticipated and credit spreads narrowed, resulting in a lower achieved reinvestment rate than assumed in the 2016 unlocking. In addition to the reinvestment rates above, actual default rates in 2017, 2016 and 2015 were lower than the long-term default rates of 0.18% assumed in the unlocking in each of the periods above.
69

Table of Contents
The 2016 net expense reduction reflects the favorable impact of an increase in projected net interest spreads on in-force business, substantially offset by the unfavorable impact of (i) changes in projected policyholder annuitization and lapse behavior, (ii) an increase in the risk premium for the uncertainty in the cash flows component of the discount rates used to value the FIA-related embedded derivative and (iii) a slight decrease in projected stock market growth over the next three years. For the 2016 unlocking, AFG assumed a net reinvestment rate (net of default and expense assumptions) of 4.24% in 2017, grading up ratably to an ultimate net reinvestment rate of 5.55% in 2022 and beyond.

Holding Company and Other — Net Investment Income
AFG recorded net investment income on investments held outside of its insurance operations of $6 million in the fourth quarter of 2017 compared to less than $1 million in the fourth quarter of 2016. The $6 million increase in the fourth quarter of 2017 as compared to the fourth quarter of 2016 is due primarily to the strong performance of certain fixed maturity investments.
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 businesses collect fees from customers for ancillary services such as workplace safety programs and premium financing. In the fourth quarter of 2017, AFG collected $20 million in fees for these services compared to $17 million in the fourth quarter of 2016. Management views this fee income, net of the $11 million in both the fourth quarter of 2017 and 2016, 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 and $5 million in the fourth quarter of 2017 and 2016, 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 Consolidate MIEs column under “Results of Operations — Segmented Statement of Earnings.” Excluding amounts eliminated in consolidation, AFG recorded a $2 million loss in other income outside of its insurance operations in the fourth quarter of 2017 due primarily to the disposal of equipment compared to income of $3 million outside of the insurance operations in the fourth quarter of 2016.

Holding Company and Other — Interest Charges on Borrowed Money
AFG’s holding companies and other operations outside of its insurance operations recorded interest expense of $20 million in the fourth quarter of 2017 compared to $21 million in the fourth quarter of 2016, a decrease of $1 million (5%). This decrease reflects slightly higher average indebtedness, more than offset by lower average interest rates on outstanding debt. The following table details the principal amount of AFG’s long-term debt balances as of December 31, 2017 compared to December 31, 2016 (dollars in millions):

The increase in average indebtedness for the fourth quarter of 2017 as compared to the fourth quarter of 2016 reflects the following financing transactions completed by AFG between October 1, 2016 and December 31, 2017:

• | Issued $350 million of 4.50% Senior Notes on June 2, 2017

• | Redeemed $230 million of 6-3/8% Senior Notes on June 26, 2017

• | Redeemed $125 million of 5-3/4% Senior Notes on August 25, 2017

Holding Company and Other — Loss on Retirement of Debt
On December 11, 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.
Holding Company and Other — Other Expenses
Excluding the loss on retirement of debt discussed above, AFG’s holding companies and other operations outside of its insurance operations recorded other expenses of $37 million in both the fourth quarter of 2017 and the fourth quarter of 2016.
Consolidated Realized Gains (Losses) on Securities AFG’s consolidated realized gains (losses) on securities, which are not allocated to segments, were gains of $6 million in the fourth quarter of 2017 compared to $51 million in the fourth quarter of 2016, a decrease of $45 million (88%). Realized gains (losses) on securities consisted of the following (in millions):

related to financial institutions and $4 million relate to investments in pharmaceutical companies. Approximately $7 million in impairment charges in the fourth quarter of 2016 are related to an equity investment in a pharmaceutical company.
Consolidated Income Taxes AFG’s consolidated provision (credit) for income taxes was an expense of $101 million for the fourth quarter of 2017 compared to a benefit of $71 million in the fourth quarter of 2016, a decrease of $172 million (242%). The following is a reconciliation of income taxes at the statutory rate of 35% to the provision (credit) for income taxes as shown in the segmented statement of earnings (dollars in millions):

| Three months ended December 31,
| 2017 |  | 2016
| Amount |  | % of EBT |  | Amount |  | % of EBT
Earnings before income taxes (“EBT”) | $ | 267 |  |  |  |  | $ | 317 |  |  |

The impact of “foreign operations” for the fourth quarter of 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 related to the cumulative losses in the Neon Lloyd’s insurance business. Due to the uncertainty concerning the realization of the deferred tax benefits associated with these losses, AFG maintains a full valuation allowance against these deferred tax assets. The $61 million decrease in the valuation allowance related to the change in the U.S. corporate tax rate is included in “Change in U.S. corporate tax rate” in the table above.
In connection with the reorganization of AFG’s Neon Lloyd’s business, in December 2016, AFG undertook a restructuring that included the liquidation for tax purposes of the foreign subsidiary that is the parent of the Neon Lloyd’s operations, resulting in a taxable loss on the liquidation on which AFG reported a $111 million tax benefit in the fourth quarter of 2016. An additional loss associated with the 2016 restructuring was deferred under U.S. tax laws, resulting in an unrecognized potential tax benefit of $48 million at December 31, 2016. On December 29, 2017, AFG entered into agreements under which certain Neon executives acquired an indirect noncontrolling interest in Neon. The sale of the noncontrolling interest in Neon resulted in the recognition for U.S. tax purposes of the loss deferred from the 2016 restructuring. AFG recorded a tax benefit of $56 million in the fourth quarter of 2017 related to the sale of the noncontrolling interest in Neon and the recognition of the previously deferred loss. See Note L — “Income Taxes” to the financial statements.
The Tax Cuts and Jobs Act of 2017 (“TCJA”), which lowers the U.S. corporate tax rate to 21% and makes other widespread changes to the U.S. tax code beginning in 2018, was enacted on December 22, 2017. 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. See Note L — “Income Taxes” to the financial statements. Although accounting for the TCJA reduced AFG’s net deferred tax asset, management expects a net favorable future economic impact from the lower corporate income tax rate, including an expected effective tax rate in 2018 of approximately 20%.
As discussed in Note B — “Acquisitions and Sale of Businesses” to the financial statements, AFG acquired the noncontrolling interest in National Interstate Corporation in November 2016. This transaction allowed National Interstate and its subsidiaries

to become members of the AFG consolidated tax group, which resulted in a tax benefit of $66 million to AFG during the fourth quarter of 2016.
Excluding the tax benefits related to the Neon restructuring, the impact of the change in the U.S. corporate tax rate and the tax benefit related to the acquisition of the noncontrolling interest in NATL, AFG’s effective tax rate was 28% for the three months ended December 31, 2017 and 34% for the three months ended December 31, 2016.
Consolidated Noncontrolling Interests AFG’s consolidated net earnings attributable to noncontrolling interests was less than $1 million for the fourth quarter of 2017 compared to $3 million for the fourth quarter of 2016.

RESULTS OF OPERATIONS — YEARS ENDED DECEMBER 31, 2017, 2016 AND 2015
Segmented Statement of Earnings AFG reports its business as four segments: (i) Property and casualty insurance (“P&C”), (ii) Annuity, (iii) Run-off long-term care and life and (iv) Other, which includes 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 years ended December 31, 2017, 2016 and 2015 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 AFG’s property and casualty insurance operations contributed $591 million in GAAP pretax earnings in 2017 compared to $577 million in 2016, an increase of $14 million (2%). Property and casualty core pretax earnings were $662 million in 2017 compared to $646 million in 2016, an increase of $16 million (2%). The increase in GAAP and core pretax earnings reflects higher underwriting profit in the Specialty casualty group, higher net investment income and lower other expenses, partially offset by lower underwriting profit in the Property and transportation and Specialty financial groups. The increase in GAAP pretax earnings also reflects the impact of a pretax non-core charge of $65 million in the second quarter of 2016 related to the exit of certain lines of business within Neon and favorable development of $18 million in the fourth quarter of 2017 in the Neon exited lines in connection with a reinsurance to

close transaction, partially offset by the impact of a $32 million pretax non-core gain on the sale of an apartment property in the second quarter of 2016 and special A&E charges of $89 million in 2017 compared to $36 million in 2016.
AFG’s property and casualty insurance operations contributed $577 million in GAAP pretax earnings in 2016 compared to $576 million in 2015, an increase of $1 million. Property and casualty core pretax earnings were $646 million in 2016 compared to $577 million in 2015, an increase of $69 million (12%). The increase in GAAP and core pretax earnings reflects improved underwriting results in the Property and transportation group and higher net investment income, partially offset by lower underwriting profit in the Specialty casualty and Specialty financial groups. GAAP pretax earnings also reflect a pretax non-core charge of $65 million in the second quarter of 2016 related to the exit of certain lines of business within Neon and a $32 million pretax non-core gain on the sale of an apartment property in the second quarter of 2016 compared to a $51 million pretax non-core gain on the sale of a hotel in the second quarter of 2015 and a $15 million pretax non-core gain on the sale of an apartment property in the fourth quarter of 2015, as well as non-core special A&E charges of $36 million in 2016 compared to $67 million in 2015.

The $521 million (9%) increase in gross written premiums in 2017 compared to 2016 reflects growth in each of the Specialty property and casualty insurance sub-segments. Overall average renewal rates increased approximately 1% in 2017.
The $149 million (3%) increase in gross written premiums in 2016 compared to 2015 reflects growth in the Property and transportation, Specialty casualty and Specialty financial sub-segments. Overall average renewal rates were flat in 2016.
Property and transportation Gross written premiums increased $184 million (7%) in 2017 compared to 2016. This increase was the result of higher gross written premiums in the crop, transportation and property and inland marine businesses, and the Singapore branch. This growth was partially offset by lower premiums resulting from an exit from the customs bond business, which was part of the ocean marine operations. Average renewal rates increased approximately 3% for this group in 2017. Reinsurance premiums ceded as a percentage of gross written premiums increased 1 percentage point in 2017 compared to 2016, reflecting a change in the mix of business and the impact of reinstatement premiums in 2017 resulting from reinsured hurricane losses.
Gross written premiums increased $49 million (2%) in 2016 compared to 2015. This increase was the result of higher premiums in the agricultural businesses, growth in the transportation businesses and higher gross written premiums from the Singapore branch, which opened for business in June 2015, partially offset by lower gross written premiums in the property and inland marine businesses. Average renewal rates increased approximately 3% for this group in 2016, including a 5% increase in National Interstate’s renewal rates. Reinsurance premiums ceded as a percentage of gross written premiums were comparable in 2016 and 2015.
Specialty casualty Gross written premiums increased $295 million (11%) in 2017 compared to 2016. New accounts written in the targeted markets businesses and higher gross written premiums at Neon, resulting from the growth of its portfolio in targeted classes of business were the primary drivers of the increase. Additionally, higher gross written premiums in the workers’ compensation businesses, primarily the result of rate increases in the state of Florida, coupled with growth in the executive liability and excess and surplus businesses contributed to the growth in gross written premiums in 2017. Average renewal rates were flat for this group in 2017. Reinsurance premiums ceded as a percentage of gross written premiums decreased 1 percentage point in 2017 compared to 2016, reflecting a change in the mix of business.
Gross written premiums increased $53 million (2%) in 2016 compared to 2015. Higher gross written premiums in the excess and surplus, targeted markets and workers’ compensation businesses were partially offset by lower premiums in the general liability business and by Neon’s exit of certain lines of business and implementation of more stringent underwriting standards at Neon. Lower premiums in the general liability business were primarily the result of competitive market conditions, re-underwriting efforts within the Florida homebuilders market and the slowdown within the energy sector. Average renewal rates decreased approximately 1% for this group in 2016, including a decrease of approximately 4% in the workers’ compensation businesses. Excluding the workers’ compensation business, average renewal rates for this group increased approximately 1% during 2016. Reinsurance premiums ceded as a percentage of gross written premiums increased 2 percentage points in 2016 compared to 2015, reflecting the cession of Neon’s UK medical malpractice business and a change in the mix of business at Neon.
Specialty financial Gross written premiums increased $42 million (6%) in 2017 compared to 2016 due primarily to higher premiums in the lending and leasing, fidelity and surety businesses. Average renewal rates for this group decreased approximately 2% in 2017. Reinsurance premiums ceded as a percentage of gross written premiums increased 2 percentage points in 2017 compared to 2016, reflecting higher cessions in the lending and leasing businesses.
Gross written premiums increased $48 million (8%) in 2016 compared to 2015 due primarily to growth in the financial institutions and surety businesses. Average renewal rates for this group decreased approximately 1% in 2016. Reinsurance premiums ceded as a percentage of gross written premiums increased 1 percentage point in 2016 compared to 2015, reflecting higher cessions in the financial institutions business, partially offset by a decline in auto dealer business, which is heavily 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.

The Specialty property and casualty insurance operations generated an underwriting profit of $317 million in 2017 compared to $337 million in 2016, a decrease of $20 million (6%). The lower underwriting profit in 2017 as compared to 2016 reflects lower underwriting profit in the Property and transportation and Specialty financial insurance sub-segments, partially offset by higher underwriting profit in the Specialty casualty insurance sub-segment. Results for each of the Specialty property and casualty insurance sub-segments reflect higher catastrophe losses in 2017 compared to 2016. Overall catastrophe losses were $140 million (3.0 points on the combined ratio) for 2017 compared to $55 million (1.3 points) for 2016. 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.
The Specialty property and casualty insurance operations generated an underwriting profit of $337 million in 2016 compared to $295 million in 2015, an increase of $42 million (14%). The higher underwriting profit in 2016 reflects higher underwriting profit in the Property and transportation sub-segment, partially offset by lower underwriting profit in the Specialty casualty and Specialty financial sub-segments. Overall catastrophe losses were $55 million (1.3 points on the combined ratio) in 2016 compared to $35 million (0.8 points) in 2015.
Property and transportation Underwriting profit for this group was $154 million in 2017 compared to $166 million in 2016, a decrease of $12 million (7%). Lower underwriting profits in the crop and ocean marine businesses were the primary drivers of these lower results, partially offset by higher underwriting profit in the transportation businesses. The crop insurance operations reported strong underwriting profitability in 2017, albeit at lower levels than in 2016. Catastrophe losses were $36 million (2.1 points on the combined ratio) and related reinstatement premiums were $2 million in 2017 compared to catastrophe losses of $31 million (1.9 points) in 2016.

Table of Contents
Underwriting profit for this group was $166 million in 2016 compared to $48 million in 2015, an increase of $118 million (246%). This improvement reflects higher underwriting profit in the crop insurance business, primarily the result of favorable growing conditions and relatively stable commodity pricing and higher underwriting profits in the transportation and property and inland marine businesses. These improved results were partially offset by an increase of $10 million in catastrophe losses in 2016 compared to 2015.
Specialty casualty Underwriting profit for this group was $104 million in 2017 compared to $78 million in 2016, an increase of $26 million (33%), reflecting favorable reserve development within Neon, including the portion of the 2015 and prior years reinsurance to close transaction attributed to ongoing lines of business, and higher underwriting profit in the excess and surplus lines and workers’ compensation businesses. These improved results were partially offset by lower underwriting profit in the executive liability business, due primarily to lower favorable prior year reserve development, adverse prior year reserve development in the targeted markets operations and higher catastrophe losses. Catastrophe losses were $71 million (3.3 points on the combined ratio) and related net reinstatement premiums were $6 million in 2017 compared to catastrophe losses of $10 million (0.5 points) in 2016.
Underwriting profit for this group was $78 million in 2016 compared to $146 million in 2015, a decrease of $68 million (47%). Higher underwriting profitability in the workers’ compensation businesses, due primarily to higher favorable prior year reserve development, and improved results in the general liability business were more than offset by adverse prior year reserve development in the excess and surplus and targeted markets businesses, current accident year trade credit losses in Neon’s political risk and trade credit business and higher catastrophe losses.
Specialty financial Underwriting profit for this group was $61 million in 2017 compared to $84 million in 2016, a decrease of $23 million (27%), reflecting lower underwriting profitability in the financial institutions business due primarily to higher catastrophe losses and adverse prior year reserve development. Catastrophe losses were $30 million (5.2 points on the combined ratio) in 2017 compared to $11 million (2.0 points) in 2016. In connection with catastrophe losses incurred in 2017, the Specialty financial sub-segment reduced profit-based commissions payable to agents by $8 million (1.1 points on the combined ratio) and paid $2 million in reinstatement premiums.
Underwriting profit for this group was $84 million in 2016 compared to $87 million in 2015, a decrease of $3 million (3%). Higher underwriting profit in the fidelity and surety businesses, primarily the result of higher favorable prior year reserve development, was more than offset by lower underwriting profit in the financial institutions and trade credit businesses, resulting primarily from lower favorable prior year reserve development.
Other specialty This group reported an underwriting loss of $2 million in 2017 compared to underwriting profit of $9 million in 2016, a decrease of $11 million (122%). The decrease is due primarily to 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.
Underwriting profit for this group was $9 million in 2016 compared to $14 million in 2015, a decrease of $5 million (36%). The decrease is due primarily to lower favorable prior year loss development in the business assumed by AFG’s internal reinsurance program from the operations that make up AFG’s other Specialty sub-segments.
Aggregate Aggregate underwriting results for AFG’s property and casualty insurance segment include the asbestos and environmental reserve charges and the Neon exited lines charge and favorable development in the Neon exited lines discussed below under “Net prior year reserve development.”

Net prior year reserve development
AFG’s Specialty property and casualty insurance operations recorded net favorable reserve development related to prior accident years of $139 million in 2017 compared to $61 million in 2016 and $37 million in 2015, an increase of $78 million (128%) and $24 million (65%), respectively.
Property and transportation Net favorable reserve development of $40 million in 2017 reflects 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, partially offset by higher than expected claim frequency and severity in the ocean marine business.
Net favorable reserve development of $21 million in 2016 reflects lower than expected losses in the crop operations and lower than expected claim severity in the property and inland marine and trucking businesses, partially offset by reserve strengthening at National Interstate and higher than expected claim frequency in the ocean marine business.
Net adverse reserve development of $15 million in 2015 reflects higher than expected claim severity at National Interstate and higher than anticipated claim frequency in the ocean marine business, partially offset by lower than expected claim severity in the property and inland marine business, agricultural operations and a run-off book of homebuilders business.
Specialty casualty Net favorable reserve development of $86 million in 2017 includes favorable reserve 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, partially offset by higher than anticipated claim severity in the targeted markets and general liability businesses and higher than anticipated severity in New York contractor claims.
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 development of $42 million, of which $24 million related to its ongoing lines of business (included in Specialty casualty) and $18 million related to the exited lines of business (discussed below and included in Neon exited lines charge).
Net favorable reserve development of $13 million in 2016 reflects lower than anticipated claim frequency and severity in workers’ compensation business, lower than expected claim severity in directors and officers liability insurance and lower than expected claim frequency and severity in excess liability business, partially offset by adverse reserve development at Neon, higher than anticipated severity in New York contractor claims, higher than anticipated claim frequency and severity in general liability insurance and higher than expected claim frequency and severity in the targeted markets business.
Net favorable reserve development of $11 million in 2015 includes lower than anticipated claim severity in workers’ compensation business, lower than anticipated claim severity and frequency in excess liability insurance and lower than expected claim severity in directors and officers liability insurance, partially offset by adverse reserve development at Neon.
Specialty financial 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.
Net favorable reserve development of $23 million in 2016 reflects lower than anticipated claim severity in the fidelity business, lower than expected claim frequency and severity in the surety business and lower than anticipated claim frequency in the financial institutions business.

Table of Contents
Net favorable reserve development of $30 million in 2015 reflects lower than anticipated claim frequency and severity in the surety business and products for financial institutions and lower than expected claim severity in the fidelity business and run-off collateral value insurance.
Other specialty In addition to the reserve development discussed above, total Specialty prior year reserve development includes net adverse reserve development of $8 million in 2017 and net favorable reserve development of $4 million in 2016 and $11 million in 2015. The 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. Favorable reserve development in 2016 and 2015 reflects amortization of deferred gains on retroactive reinsurance and 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 $89 million in 2017, $36 million in 2016 and $67 million in 2015.
Neon exited lines charge See “Net prior year reserve development” under “Results of Operations — Property and Casualty Insurance Segment” for the quarters ended December 31, 2017 and 2016 for a discussion of the $57 million in adverse reserve development recorded as part of a $65 million non-core charge related to the exit of certain lines of business within Neon, AFG’s Lloyd’s insurer. Consistent with the treatment of the exited lines charge in 2016, the $18 million in favorable development related to the Neon exited lines recorded in connection with the December 2017 reinsurance to close transaction (discussed above under Specialty casualty) was treated as non-core.
Aggregate Aggregate net prior accident years reserve development for AFG’s property and casualty insurance segment includes the A&E charges, the Neon exited lines charge and the favorable development on the Neon exited lines mentioned above and adverse reserve development of $4 million in 2017 and $3 million in 2015 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 $140 million in 2017 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. Catastrophe losses of $55 million in 2016 resulted primarily from winter storms in the first quarter, storms in Texas in the second quarter, flooding in Louisiana and multiple storms in the southern United States in the third quarter and Hurricane Matthew in the fourth quarter. Catastrophe losses of $35 million in 2015 resulted primarily from winter storms in the first quarter, multiple storms in the midwestern and central United States in the second and third quarters and flooding in the midwestern United States in the fourth quarter.

The increase in average invested assets and net investment income in the property and casualty insurance segment in 2017 compared to 2016 is due primarily to growth in the property and casualty insurance segment. The property and casualty insurance segment’s overall yield on investments was 3.64% in 2017 compared to 3.66% in 2016, a decrease of 0.02 percentage points reflecting the impact of lower yields available in the financial markets and lower income from certain investments that are required to be carried at fair value through earnings, partially offset by higher income from equity in the earnings of limited partnerships and similar investments.
The increase in average invested assets in the property and casualty insurance segment in 2016 as compared to 2015 is due primarily to growth in the segment. The $31 million increase in the property and casualty insurance segment’s net investment income reflects a $13 million increase in income from certain investments that are required to be carried at fair value through earnings, an $11 million increase in equity in the earnings of limited partnerships and similar investments and the increase in average invested assets, partially offset by slightly higher investment expenses and lower yields available in the financial markets. The property and casualty segment’s overall yield on investments (net investment income as a percentage of average invested assets) was 3.66% in 2016 compared to 3.56% in 2015, reflecting the higher income from investments carried at fair value and partnership earnings discussed above, partially offset by the impact of the lower current market yields discussed above.

Other income for AFG’s property and casualty insurance operations includes $3 million in 2017 and $4 million in 2016 in death benefits from life insurance policies.
AFG and its consolidated subsidiaries incurred $10 million in transaction expenses in 2016 related to GAI’s acquisition of all of the NATL common stock that it did not already own. These expenses consisted primarily of financial advisory and legal services. See Note B — “Acquisitions and Sale of Businesses” to the financial statements.
Interest expense for AFG’s property and casualty insurance operations includes interest charges on long-term debt within the property and casualty operations.
Annuity Segment — Results of Operations
AFG’s annuity operations contributed $380 million in pretax earnings in 2017 compared to $368 million in 2016, an increase of $12 million (3%). AFG’s annuity segment results in 2017 compared to 2016 reflect an 11% increase in average annuity investments (at amortized cost), partially offset by lower investment yields due to the run-off of higher yielding investments and higher general and administrative expenses. Included in these results is the change in fair value of derivatives related to FIAs, which had a negative impact of $33 million in 2017 compared to $27 million in 2016. Both periods reflect the negative impact of lower than anticipated interest rates, partially offset by the positive impact of a higher stock market on the fair value accounting for FIAs. AFG’s periodic detailed review (“unlocking”) of the major actuarial assumptions underlying its annuity operations resulted in a net annuity charge of $3 million in 2017 compared to a net annuity expense reduction of $1 million in 2016.
AFG’s annuity operations contributed $368 million in pretax earnings in 2016 compared to $331 million in 2015, an increase of $37 million (11%). The increase in AFG’s annuity segment results in 2016 compared to 2015 reflects higher investment income from certain investments that are required to be carried at fair value through earnings and a 12% increase in average annuity investments (at amortized cost), partially offset by lower investment yields due to the run-off of higher yielding investments and higher general and administrative expenses. The change in fair value of derivatives related to FIAs had a negative impact of $27 million in 2016 compared to $23 million in 2015. For 2016, the negative impact of a significant drop in interest rates on fair value accounting for FIAs was partially offset by the positive impact of an increase in the stock market. For 2015, fair value accounting for FIAs was negatively impacted by a significant decrease in the stock market and a slightly lower than expected increase in interest rates. Operating earnings also included a net unlocking expense reduction of $1 million in 2016 compared to $10 million in 2015.

Annuity Net Investment Income
Net investment income in 2017 was $1.46 billion compared to $1.36 billion in 2016, an increase of $102 million (8%). 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 0.14 percentage points to 4.63% from 4.77% in 2017 compared to 2016. This decline in net investment yield reflects (i) the investment of new premium dollars at lower yields as compared to the existing investment portfolio and (ii) the impact of the reinvestment of proceeds from maturity and redemption of higher yielding investments at the lower yields available in the financial markets. During 2017, $4.9 billion in annuity segment investments with an average yield of 5.14% were redeemed or sold while the investments purchased during 2017 (with new premium dollars and the redemption/sale proceeds) had an average yield at purchase of 3.94%.
Net investment income in 2016 was $1.36 billion compared to $1.22 billion in 2015, an increase of $132 million (11%). This increase reflects primarily the growth in AFG’s annuity business and higher income from certain investments that are required to be carried at fair value through earnings, partially offset by the impact of lower in-force investment yields. The overall yield earned on investments in AFG’s annuity operations decreased by 0.06 percentage points to 4.77% from 4.83% in 2016 compared to 2015. This decline in net investment yield reflects (i) the investment of new premium dollars at lower yields as compared to the existing investment portfolio and (ii) the impact of the reinvestment of proceeds from maturity and redemption

of higher yielding investments at the lower yields available in the financial markets, partially offset by higher investment income from certain investments that are required to be carried at fair value through earnings. During 2016, $4.0 billion in annuity segment investments with an average yield of 5.51% were redeemed or sold while the investments purchased during 2016 (with new premium dollars and the redemption/sale proceeds) had an average yield at purchase of 4.21%.
Annuity Interest Credited — Fixed
Interest credited — fixed in 2017 was $633 million compared to $574 million in 2016, an increase of $59 million (10%). The impact of growth in the annuity business was partially offset by lower interest crediting rates on new premiums as compared to the crediting rates on policyholder funds surrendered or withdrawn. The average interest rate credited to policyholders, calculated as interest credited divided by average fixed annuity benefits accumulated, decreased 0.03 percentage points to 2.01% in 2017 from 2.04% in 2016.
Interest credited — fixed in 2016 was $574 million compared to $532 million in 2015, an increase of $42 million (8%). The impact of growth in the annuity business was partially offset by lower interest crediting rates on new premiums as compared to the crediting rates on policyholder funds surrendered or withdrawn. The average interest rate credited to policyholders decreased 0.10 percentage points to 2.04% in 2016 from 2.14% in 2015.
Annuity Net Interest Spread
AFG’s net interest spread decreased 0.11 percentage points to 2.62% from 2.73% in 2017 compared to 2016 due primarily to lower fixed maturity investment yields, partially offset by the impact of lower crediting rates. Features included in current annuity 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 increased 0.04 percentage points to 2.73% in 2016 from 2.69% in 2015 as the impact of lower in-force investment yields was more than offset by lower crediting rates and higher income from certain investments that are required to be carried at fair value through earnings.
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 $43 million in 2017 compared to $50 million in 2016, a decrease of $7 million (14%). Excluding the impact of unlocking charges of $3 million in 2017 and $1 million in 2016 related to unearned revenue, annuity policy charges and other miscellaneous income were $46 million in 2017 compared to $51 million in 2016, a decrease of $5 million (10%). Other miscellaneous income includes $1 million from the sale of real estate in 2017 compared to $5 million in 2016. 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 0.04 percentage points to 0.11% in 2017 from 0.15% in 2016.
Annuity policy charges and other miscellaneous income were $50 million in 2016 compared to $55 million in 2015, a decrease of $5 million (9%). Other miscellaneous income includes $5 million in income from the sale of real estate in 2016 compared to $6 million in 2015. Excluding the impact of unlocking charges of $1 million in 2016 and $2 million in 2015 related to unearned revenue, annuity policy charges and other miscellaneous income were $51 million in 2016 compared to $57 million in 2015, a decrease of $6 million (11%). 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 0.03 percentage points to 0.15% in 2016 from 0.18% in 2015.

Other Annuity Benefits, Net of Guaranteed Withdrawal Benefit Fees
Other annuity benefits, net of guaranteed withdrawal benefit fees (excluding the impact of unlocking) were $89 million in 2017, $92 million in 2016 and $87 million in 2015, representing a decrease of $3 million (3%) in 2017 compared to 2016 and an increase of $5 million (6%) in 2016 compared to 2015. As a percentage of average fixed annuity benefits accumulated, these net expenses decreased 0.05 percentage points to 0.28% in 2017 from 0.33% in 2016 and decreased 0.02 percentage points to 0.33% in 2016 from 0.35% in 2015. 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,
| 2017 |  | 2016 |  | 2015
Change in expected death and annuitization reserve | $ | 18 |  |  | $ | 18 |  |  | $ | 19 |
Amortization of sales inducements | 19 |  |  | 24 |  |  | 26 |
Change in guaranteed withdrawal benefit reserve | 67 |  |  | 69 |  |  | 63 |
Change in other benefit reserves | 45 |  |  | 34 |  |  | 22 |
Other annuity benefits | 149 |  |  | 145 |  |  | 130 |
Offset guaranteed withdrawal benefit fees | (60 | ) |  | (53 | ) |  | (43 | )
Other annuity benefits, net | $ | 89 |  |  | $ | 92 |  |  | $ | 87 |

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. The guaranteed withdrawal benefit reserve related to FIAs is 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.
The $5 million increase in other annuity benefits, net of guaranteed withdrawal benefit fees in 2016 compared to 2015 primarily reflects growth in the business.
See “Annuity Unlocking” below for a discussion of the impact that the periodic review of actuarial assumptions had on annuity benefits expense.
Annuity Acquisition Expenses
Excluding the impact of unlocking charges (expense reductions) discussed under “Annuity Unlocking” below, AFG’s amortization of DPAC and commission expenses as a percentage of average fixed annuity benefits accumulated was 0.62% in 2017 compared to 0.70% in 2016 and 0.74% in 2015 and has generally ranged between 0.75% and 0.85%. Variances from the general range relate primarily to the impact of (i) material changes in interest rates or the stock market on AFG’s fixed-indexed annuity business, and (ii) differences in actual experience from actuarially projected estimates and assumptions. For example, the negative impact of significantly lower than anticipated interest rates during 2017 and 2016, and the significant stock market decrease in 2015 on the fair value of derivatives related to fixed-indexed annuities (discussed below) resulted in a partially offsetting deceleration in the amortization of DPAC.
The table below illustrates the estimated impact of fair value accounting for derivatives related to fixed-indexed annuities on annuity acquisition expenses as a percentage of average fixed annuity benefits accumulated:

| Year ended December 31,
| 2017 |  | 2016 |  | 2015
Before the impact of changes in the fair value of derivatives related to FIAs on the amortization of DPAC | 0.74 | % |  | 0.79 | % |  | 0.82 | %
Impact of changes in fair value of derivatives related to FIAs on the amortization of DPAC (*) | (0.12 | %) |  | (0.09 | %) |  | (0.08 | %)

(*) | An estimate of the acceleration/deceleration in the amortization of deferred policy acquisition costs resulting from fair value accounting for derivatives related to fixed-indexed annuities.

See “Annuity Unlocking” below for a discussion of the impact that the periodic review 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 write-offs of DPAC or PVFP in the future.

Annuity Other Expenses
Annuity other expenses were $121 million in 2017, $110 million in 2016 and $96 million in 2015, representing an increase of $11 million (10%) in 2017 compared to 2016 and an increase of $14 million (15%) in 2016 compared to 2015. 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 0.01 percentage points to 0.37% in 2017 from 0.38% in 2016 and increased 0.02 percentage points to 0.38% in 2016 from 0.36% in 2015. The increase in annuity other expenses in 2017 compared to 2016 and 2016 compared to 2015 reflects primarily growth in the business and an increase in the number of sales personnel focused on new initiatives and increased market share within existing financial institutions and retail marketing organizations.
Change in Fair Value of Derivatives Related to Fixed-Indexed Annuities
AFG’s fixed-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 of call options on the appropriate index. AFG’s strategy is designed so that the change in the fair value of the call option assets will generally offset the economic change in the liabilities from the index participation. Both the index-based component of the annuities (an embedded derivative) and the related call 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 index-based component (embedded derivative) of AFG’s annuity benefits accumulated, see Note D — “Fair Value Measurements” to the financial statements. In addition, the change in the fair value of the embedded derivative includes interest accreted on the FIA embedded derivative reserve of $14 million in 2017, $4 million in 2016 and $1 million in 2015 (before the related impact on the amortization of sales inducements and deferred policy acquisition costs).
Excluding the impact of unlocking charges, the net change in fair value of derivatives related to fixed-indexed annuities increased annuity benefits by $70 million in 2017, $53 million in 2016 and $45 million in 2015. The increase in 2017 and 2016 reflects the negative impact of significantly lower than anticipated interest rates on the fair value of these derivatives, partially offset by the positive impact of strong stock market performance in both periods. The increase in 2015 reflects the negative impact of the decline in the stock market and lower than anticipated interest rates on these derivatives. As a percentage of average fixed annuity benefits accumulated, this net expense increased 0.03 percentage points to 0.22% in 2017 from 0.19% in 2016, and increased 0.01 percentage points to 0.19% in 2016 from 0.18% in 2015.
Fluctuations in interest rates and the stock market, among other factors, can cause volatility in the periodic measurement of fair value of the embedded derivative that management believes can be inconsistent with the long-term economics of these products. The table below illustrates the impact of fair value accounting for derivatives related to fixed-indexed annuities on the annuity segment’s earnings before income taxes (dollars in millions):

(*) | An estimate of the related acceleration/deceleration of amortization of deferred sales inducements and deferred policy acquisition costs.

As illustrated in the table above, the change in fair value of derivatives related to fixed-indexed annuities, including the related impact on amortization of DPAC decreased the annuity segment’s earnings before income taxes by $33 million, $27 million and $23 million in 2017, 2016 and 2015, respectively.
See “Annuity Unlocking” below for a discussion of the impact that the periodic review of actuarial assumptions had on the change in the fair value of the embedded derivative liability.
Annuity Net Spread Earned on Fixed Annuities
AFG’s net spread earned on fixed annuities decreased 0.06 percentage points to 1.23% in 2017 from 1.29% in 2016 due primarily to the 0.11 percentage points decrease in AFG’s net interest spread, partially offset by other small net positive items.

Table of Contents
AFG’s net spread earned on fixed annuities increased 0.03 percentage points to 1.29% in 2016 from 1.26% in 2015 due primarily to the 0.04 percentage points increase in AFG’s net interest spread.
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 2017, 2016 and 2015 (in millions):

Statutory Annuity Premiums
AFG’s annuity operations generated statutory premiums of $4.34 billion in 2017, $4.44 billion in 2016 and $4.14 billion in 2015, a decrease of $94 million (2%) in 2017 compared to 2016 and an increase of $295 million (7%) in 2016 compared to 2015. The following table summarizes AFG’s annuity sales (dollars in millions):

| Year ended December 31, |  | % Change
2017 |  | 2016 |  | 2015 |  | 2017 - 2016 |  | 2016 - 2015

Retail single premium annuities — indexed | 1,723 |  |  | 1,714 |  |  | 1,864 |  |  | 1 | % |  | (8 | %)
Retail single premium annuities — fixed | 83 |  |  | 82 |  |  | 70 |  |  | 1 | % |  | 17 | %
Education market — fixed and indexed annuities | 174 |  |  | 184 |  |  | 194 |  |  | (5 | %) |  | (5 | %)
Total fixed annuity premiums | 4,313 |  |  | 4,398 |  |  | 4,098 |  |  | (2 | %) |  | 7 | %
Variable annuities | 28 |  |  | 37 |  |  | 42 |  |  | (24 | %) |  | (12 | %)
Total annuity premiums | $ | 4,341 |  |  | $ | 4,435 |  |  | $ | 4,140 |  |  | (2 | %) |  | 7 | %

Management believes the 2% decrease in annuity premiums in 2017 compared to 2016 is the result of AFG’s adherence to pricing discipline in a relatively low and decreasing interest rate environment during the year, as well as from aggressive pricing in certain of AFG’s competitors.
Management attributes the 7% increase in annuity premiums in 2016 compared to 2015 to growth in the annuity industry, and new products, additional staffing, and increased market share within existing financial institutions. This growth slowed in the

second half of 2016 as a result of AFG’s reduction in crediting rates on its annuities in 2016 due to the decline in market interest rates; these crediting rate reductions were made to maintain appropriate returns on new business.
Annuity Unlocking
In 2017, 2016 and 2015, AFG conducted its detailed review (“unlocking”) of the major actuarial assumptions underlying its annuity operations. As a result of these reviews, AFG recorded a net charge related to its annuity business of $3 million in 2017 and a net expense reduction of $1 million in 2016 and $10 million in 2015, which impacted AFG’s financial statements as follows (in millions):

Run-off Long-Term Care and Life Segment — Results of Operations AFG’s run-off long-term care and life segment contributed GAAP pretax earnings of $6 million and $4 million in 2017 and 2016, respectively, compared to a loss of $152 million in 2015. Results for 2015 include a $166 million pretax non-core realized loss on the sale of the subsidiaries containing substantially all of AFG’s run-off long-term care insurance business. See Note B — “Acquisitions and Sale of Businesses” to the financial statements. The following table details AFG’s GAAP and core earnings (loss) before income taxes from its run-off long-term care and life operations in 2017, 2016 and 2015 (dollars in millions):

GAAP earnings (loss) before income taxes | $ | 6 |  |  | $ | 4 |  |  | $ | (152 | ) |  | 50 | % |  | (103 | %)

The $4 million increase in core earnings before income taxes in 2017 compared to 2016 reflects the impact of improved life claims experience.
The decrease in long-term care net earned premiums and benefit expense in 2016 compared to 2015 is due to the sale of subsidiaries containing substantially all of AFG’s run-off long-term care insurance business in December of 2015.
Substantially all of the core earnings before income taxes in AFG’s run-off long-term care and life segment in 2015 represent earnings from AFG’s long-term care business.

Holding Company and Other — Net Investment Income
AFG recorded net investment income on investments held outside of its insurance operations of $14 million, $6 million and $4 million in 2017, 2016 and 2015, respectively. The $8 million increase in 2017 as compared to 2016 is due primarily to the impact of strong market performance on a small portfolio of securities that are classified as “trading” and are carried at fair value through net investment income and strong performance of certain fixed maturity investments.
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 businesses collect fees from customers for ancillary services such as workplace safety programs and premium financing. In 2017, AFG collected $66 million in fees for these services compared to $60 million in 2016 and $54 million in 2015. Management views this fee income, net of the $41 million in 2017, $41 million in 2016 and $38 million in 2015, 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. These fees are shown in other income and the related expenses are shown in other expenses in AFG’s Statement of Earnings.
Holding Company and Other — Other Income
Other income in the table above includes $18 million, $17 million and $15 million in 2017, 2016 and 2015, 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 insurance operations of $4 million in 2017, $6 million in 2016 and $9 million in 2015.
Holding Company and Other — Interest Charges on Borrowed Money
AFG’s holding companies and other operations outside of its insurance operations recorded interest expense of $85 million in 2017 compared to $77 million in 2016, an increase of $8 million (10%). This increase reflects higher average indebtedness during 2017 compared to 2016, partially offset by a lower weighted average interest rate on outstanding debt.
The increase in average indebtedness for 2017 as compared to 2016 reflects the following financing transactions completed by AFG between January 1, 2016 and December 31, 2017:

• | Issued $300 million of 3.50% Senior Notes in August 2016

• | 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

AFG’s holding companies and other operations outside of its insurance operations recorded interest expense of $77 million in 2016 compared to $73 million in 2015, an increase of $4 million (5%). This increase reflects higher average indebtedness during 2016 compared to 2015, partially offset by a lower weighted average interest rate on outstanding debt and the favorable impact of the interest rate swap on the 9-7/8% Senior Notes due June 2019 that was entered into in June 2015.
The increase in average indebtedness for 2016 as compared to 2015 reflects the following financing transactions completed by AFG between January 1, 2015 and December 31, 2016:

• | Issued $300 million of 3.50% Senior Notes in August 2016

• | Issued $150 million of 6% Subordinated Debentures in November 2015

• | Redeemed $132 million of 7% Senior Notes in September 2015

Holding Company and Other — A&E Charges
As a result of the comprehensive external studies and internal review 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 insurance operations recorded non-core special charges of $24 million in 2017, $5 million in 2016 and $12 million in 2015 to increase liabilities related to the A&E exposures of AFG’s former railroad and manufacturing operations. The charges in 2017 and 2016 are due to relatively small movements across several sites that primarily reflect changes in the scope and costs of investigation. In addition, AFG has seen a small increase in claims arising from exposure to deleterious substances other than asbestos, which has caused it to increase its estimated future liability. The charge in 2015 related to slightly higher estimated costs at sites where remediation is underway, coupled with higher estimated cleanup costs at a limited number of sites. Total charges recorded to increase liabilities for A&E exposures of AFG’s former railroad and manufacturing operations (included in other expenses) were $31 million in 2017, $20 million in 2016 and $22 million in 2015.
Holding Company and Other — Loss on Retirement of Debt
On December 11, 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 on June 26, 2017 and $4 million related to the redemption of its $125 million outstanding 5-3/4% Senior Notes due 2042 at par value on August 25, 2017.
AFG wrote off unamortized debt issuance costs of $4 million related to the redemption of its $132 million outstanding 7% Senior Notes due 2050 at par value on September 30, 2015.
Holding Company and Other — Other Expenses
Excluding the non-core special A&E charges and the non-core losses on retirement of debt discussed above, AFG’s holding companies and other operations outside of its insurance operations recorded other expenses of $134 million in 2017 compared to $128 million in 2016, an increase of $6 million (5%). This increase reflects higher holding company expenses related to employee benefit plans that are tied to stock market performance, partially offset by the impact of a $5 million donation to the University of Cincinnati College of Business in 2016. AFG’s holding companies and other operations outside of its insurance operations recorded other expenses of $128 million in 2016 compared to $115 million in 2015, an increase of $13 million (11%). This increase reflects higher holding company expenses related to employee benefit plans that are tied to stock market

performance, a $5 million donation to the University of Cincinnati College of Business in 2016 and higher expenses related to AFG’s former railroad and manufacturing operations.
Consolidated Realized Gains (Losses) on Securities AFG’s consolidated realized gains (losses) on securities, which are not allocated to segments, were gains of $5 million in 2017 compared to $19 million in 2016, a decrease of $14 million (74%). AFG’s consolidated realized gains (losses) on securities were gains of $19 million in 2016 compared to losses of $19 million in 2015, an increase of $38 million (200%).

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.
AFG’s impairment charges on securities in 2016 consist of $93 million on equity securities and $38 million on fixed maturities. Approximately $70 million in impairment charges in 2016 are related to financial institutions, $19 million are on energy related investments and $7 million relates to a pharmaceutical company.
AFG’s impairment charges on securities in 2015 consist of $94 million on equity securities, $43 million on fixed maturities and $3 million on other investments. Approximately $41 million of the charges are on real estate and mortgage related investments, $38 million are on energy related investments and $12 million are on investments in asset managers.
Consolidated Realized Gains (Losses) on Subsidiaries In 2015, AFG recorded a pretax realized loss of $166 million on the sale of subsidiaries containing substantially all of AFG’s run-off long-term care insurance business. In the second quarter of 2016, AFG received additional proceeds based on the final closing balance sheet and adjusted certain accrued expense estimates associated with the sale, resulting in a $2 million pretax favorable adjustment to the loss recorded in 2015. See Note B — “Acquisitions and Sale of Businesses” to the financial statements. In addition, AFG recorded a $5 million pretax realized gain in 2015 representing an adjustment to the previously recognized loss on a small property and casualty subsidiary sold several years earlier.
Consolidated Income Taxes AFG’s consolidated provision for income taxes was $247 million in 2017 compared to $119 million in 2016, an increase of $128 million (108%). AFG’s consolidated provision for income taxes was $119 million in 2016 compared to $195 million in 2015, a decrease of $76 million (39%). See Note L — “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 attributable to noncontrolling interests was $2 million in 2017 compared to $19 million in 2016, a decrease of $17 million (89%). AFG’s consolidated net earnings attributable to noncontrolling interests was $19 million in 2016 compared to $18 million in 2015, an increase of $1 million (6%). The following table details net earnings in consolidated subsidiaries attributable to holders other than AFG (dollars in millions):

Other noncontrolling interests includes $2 million related to the gain on the sale of a hotel property in the first quarter of 2017, $4 million related to the gain on the sale of an apartment property in the second quarter of 2016 and $6 million related to the gain on the sale of a hotel in the second quarter of 2015. All three properties were owned by an 80%-owned subsidiary of GAI.
RECENTLY ADOPTED ACCOUNTING STANDARDS
In the fourth quarter of 2017, AFG adopted Accounting Standards Update (“ASU”) 2017-04, which simplifies the test for goodwill impairment. Under the previous guidance, if the quantitative test for impairment indicated that the carrying value of a reporting unit exceeded its fair value, an entity had to perform procedures to determine the fair value (at the impairment testing date) of its assets and liabilities (including unrecognized assets and liabilities) following the procedure that would be required in determining the fair value of assets acquired and liabilities assumed in a business combination. Under the new guidance, an impairment charge is measured as the excess of the reporting unit’s carrying value over its fair value (up to the full amount of the goodwill). Because the annual impairment testing of AFG’s goodwill in 2017 did not require quantitative testing, the implementation of the new guidance had no impact on AFG’s results of operations or financial position. In addition, AFG does not expect the new guidance to have a material effect on its results of operations or financial position in future periods.
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.
See Note A — “Accounting Policies — Managed Investment Entities” to the financial statements for a discussion of accounting guidance adopted on January 1, 2016, which impacts the consolidation of collateralized financing entities such as CLOs, as well as limited partnerships and similar investments.
See Note A — “Accounting Policies — Debt Issuance Costs” to the financial statements for a discussion of accounting guidance adopted on January 1, 2016, which impacted the presentation of debt issuance costs.
See Note A — “Accounting Policies — Stock-Based Compensation” to the financial statements for a discussion of accounting guidance adopted in the fourth quarter of 2016 (effective January 1, 2016), which impacted the accounting for share-based payment transactions.
See Note B — “Acquisitions and Sale of Businesses” to the financial statements for a discussion of accounting guidance adopted on January 1, 2015, that impacts the determination of when a component of an entity qualifies for presentation as a discontinued operation.
See Note O — “Insurance — Property and Casualty Insurance Reserves” to the financial statements for a discussion of accounting guidance adopted for annual reporting beginning in 2016, which requires additional disclosures about the liability for unpaid losses and loss adjustment expenses (including accident year information).
ACCOUNTING STANDARDS TO BE ADOPTED
In January 2016, the FASB issued ASU 2016-01, Financial Instruments – Overall: Recognition and Measurement of Financial Assets and Financial Liabilities 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, clarifies that the need for a valuation allowance on a deferred tax asset related to available for sale securities should be evaluated with other deferred tax assets and modifies disclosure requirements for financial instruments. AFG will be required to adopt the updated guidance effective January 1, 2018 (early adoption is not permitted). Although recording changes in the fair value of investments in equity securities in net earnings will result in more volatility in AFG’s Statement of Earnings, it is not expected to have a material effect on the carrying value of AFG’s investments or on overall shareholders’ equity as AFG’s investments in equity securities are currently carried at fair value through accumulated other comprehensive income. At the date of adoption, the net unrealized gain on equity securities included in AOCI will be reclassified to retained earnings in the Balance Sheet as the cumulative effect of an accounting change.
In February 2016, the FASB issued ASU 2016-02, Leases, 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. Qualitative and quantitative disclosures of the amount, timing and uncertainty of cash flows arising from leases will also be required. Although the guidance allows for early adoption, AFG expects to adopt the updated guidance effective January 1, 2019 (when it is required). The guidance will require the earliest comparative period presented to

include the measurement and recognition of existing leases with an adjustment to shareholders’ equity as if the updated guidance had always been applied. Although the guidance will result in higher assets and higher liabilities from the recognition of assets and liabilities related to operating leases, it does not change the manner in which lease expense is recognized in the statement of earnings. Although management is currently evaluating the impact of this guidance, AFG does not expect it to have a material effect on its results of operations or financial position.
In June 2016, the FASB issued ASU 2016-13, Financial Instruments – Credit Losses: Measurement of Credit Losses on Financial Instruments, which provides a new credit loss model for determining credit-related impairments for financial instruments measured at amortized cost (e.g. mortgage loans or 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. The expected credit losses, and subsequent increases or decreases in such losses, will be recorded immediately through realized gains (losses) 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 the income statement through realized gains (losses). AFG will be required to adopt this guidance effective January 1, 2020. 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 adopted.

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 market 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.

Fair value of fixed maturity portfolio |  | $ | 38,727 |  |  | $ | 34,903 |
Percentage impact on fair value of 100 bps increase in interest rates |  | (5.0 | %) |  | (5.0 | %)
Pretax impact on fair value of fixed maturity portfolio |  | $ | (1,936 | ) |  | $ | (1,745 | )

Estimated after-tax impact on accumulated other comprehensive income |  | $ | (937 | ) |  | $ | (679 | )

(*) | Reflects a U.S. corporate tax rate of 21% for the December 31, 2017 illustration and 35% for December 31, 2016.

Municipal bonds represented approximately 18% of AFG’s fixed maturity portfolio at December 31, 2017. 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, 2017, approximately 77% of the municipal bond portfolio was held in revenue bonds, with the remaining 23% held in general obligation bonds. AFG does not own general obligation bonds issued by Puerto Rico.
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. In 2003, AFG began issuing products with guaranteed minimum interest rates (“GMIRs”) of less than 2%; almost all new business since late 2010 has been issued at a 1% GMIR. At December 31, 2017, AFG could reduce the average crediting rate on approximately $25 billion of traditional fixed and fixed-indexed annuities without guaranteed withdrawal benefits by approximately 92 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, 2017, 2016 and 2015 — Net Spread on Fixed Annuities,” the interest credited rate as a percent of fixed annuity benefits accumulated on AFG’s in-force block of fixed annuities was 2.01% for the year ended December 31, 2017. Management estimates that the interest credited rate on this in-force business will range from 2.00% to 2.10% over the next five years. This rate reflects actuarial assumptions as to (i) expected investment spreads, (ii) deaths, (iii) annuitizations, (iv) surrenders and other withdrawals and (v) renewal premiums. Actual experience and changes in actuarial assumptions may result in different effective crediting 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.

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.

(*) | Fair value of annuity benefits accumulated excluding life contingent annuities in the payout phase (carrying value of $206 million at December 31, 2017 and $204 million at December 31, 2016).

AFG’s fixed-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 of call options on the appropriate index. AFG’s strategy is designed so that the change in the fair value of the call option assets 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 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):

(*) | In June 2015, AFG entered into an interest rate swap that effectively converts its 9-7/8% Senior Notes due 2019 to a floating rate of three-month LIBOR plus 8.099% (9.0624% at December 31, 2016). The 9-7/8% Senior Notes appear in the table above at December 31, 2016 (at the contractual 9-7/8% interest rate) because the notes themselves are fixed-rate obligations. The swap was terminated in December 2017 contemporaneously with the redemption of the 9-7/8% Senior Notes.

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 2017 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, 2017, 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, 2017. The attestation report of AFG’s independent registered public accounting firm on AFG’s internal control over financial reporting as of December 31, 2017, 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, 2017, 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, 2017, 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, 2017 and 2016, and 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, 2017, and the related notes and financial statement schedules listed in the Index at Item 15(a)(2) and our report dated February 23, 2018, 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.

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, 2017, 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.
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 significant nonrecurring fair value measurements of nonfinancial assets and liabilities in 2017 or 2016.
Investments Fixed maturity and equity securities classified as “available for sale” are reported at fair value with unrealized gains and losses included in accumulated other comprehensive income (“AOCI”) in AFG’s Balance Sheet. Fixed maturity and equity 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.
In January 2016, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2016-01, which, among other things, will require all equity securities currently classified as “available for sale” to be reported at fair value, with holding gains and losses recognized in net earnings, instead of AOCI. AFG will be required to adopt this guidance effective January 1, 2018. At the date of adoption, the $221 million net unrealized gain on equity securities included in AOCI as of December 31, 2017 will be reclassified to retained earnings as the cumulative effect of an accounting change.
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.
Gains or losses on securities 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
F-7

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — CONTINUED
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 MBS) and (ii) the equity-based component of certain annuity products (included in annuity benefits accumulated) and related equity index call 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. Any hedge ineffectiveness is immediately recorded in current period 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.
For derivatives that are designated and qualify as highly effective fair value hedges, changes in the fair value of the derivative, along with changes in the fair value of the hedged item attributable to the hedged risk, are recognized in current period earnings.
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

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — CONTINUED
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, long-term care 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 the 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.
On January 1, 2016, AFG adopted ASU 2015-02, which amended certain consolidation accounting guidance, including the VIE guidance that applies to collateralized financing entities such as CLOs. The new guidance affects how fee arrangements with CLO asset managers impact the determination of the primary beneficiary of those entities. Due to the significance of AFG’s investments in the CLOs that it manages, the new guidance did not impact the consolidation of AFG’s currently outstanding CLOs. The new guidance also impacted the consolidation analysis that applies to limited partnerships and similar entities, but did not result in a change to the accounting for AFG’s existing investments in those entities.
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.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — CONTINUED
Prior to the adoption of new guidance effective January 1, 2015, measuring both the CLO assets and CLO liabilities at separately determined fair values resulted in a difference between the carrying value of the CLO assets and the carrying value of the CLO liabilities that was not attributable to AFG’s ownership interest in the CLOs. This difference was recorded as “appropriated retained earnings — managed investment entities” in AFG’s Balance Sheet. In accordance with the guidance adopted in 2015, the amount reported as “appropriated retained earnings — managed investment entities” at December 31, 2014 was reclassified to “liabilities of managed investment entities” on January 1, 2015 as the cumulative effect of an accounting change.
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 expense and decreases for policy charges are credited to other income.
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).

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — CONTINUED
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 amortized over the life of the related debt using the effective interest method. Effective January 1, 2016, AFG adopted (on a retrospective basis) ASU 2015-03, which requires debt issuance costs to be presented in the balance sheet as a direct reduction in the carrying value of long-term debt (consistent with the treatment of debt discounts) with the periodic amortization of such costs included in interest expense. Debt issuance costs related to AFG’s revolving credit facilities will continue to be included in other assets in AFG’s Balance Sheet. Prior to AFG’s adoption of ASU 2015-03, AFG reported unamortized debt issuance costs as a deferred charge asset (included in other assets) in AFG’s Balance Sheet and the periodic amortization was included in other expenses in AFG’s Statement of Earnings. The updated guidance did not affect the overall recognition and measurement guidance for debt issuance costs. Accordingly, the guidance did not have an overall impact on AFG’s Shareholders’ Equity or results of operations.
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.
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 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 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 L — “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. See Note K — “Shareholders’ Equity” for further information.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — CONTINUED
In the fourth quarter of 2016, AFG early adopted ASU 2016-09, which, among other things, requires excess tax benefits or deficiencies for share-based payments to be recorded through income tax expense in the statement of earnings instead of directly to capital surplus (as required under the previous guidance). As a result, AFG’s Statement of Earnings includes a tax benefit of $17 million in 2017 and $9 million in 2016 that under the previous guidance would have been recorded directly to capital surplus. In addition, the new guidance allows entities to elect to account for forfeitures of awards when they occur rather than accruing expense based on an estimate of expected forfeitures (as required under the previous guidance). AFG has elected to account for forfeitures as they occur. The resulting cumulative effect of accounting change of less than $1 million was recorded directly to retained earnings on January 1, 2016.
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: 2017 – 2.0 million, 2016 – 1.6 million and 2015 – 1.8 million.
AFG’s weighted average diluted shares outstanding excludes the following anti-dilutive potential common shares related to stock compensation plans: 2017 – none, 2016 – 0.4 million and 2015 – 1.1 million. Adjustments to net earnings attributable to shareholders in the calculation of diluted earnings per share were nominal in the 2017, 2016 and 2015 periods.
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 and property and equipment. “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.
Effective October 1, 2016, AFG early adopted (on a retrospective basis) ASU 2016-15, which addresses the diversity in practice in how certain cash receipts and cash payments are presented in the statement of cash flows. Among other things, this guidance requires proceeds received from the settlement of corporate-owned life insurance policies to be classified as cash inflows from investing activities and allows premiums paid for policies to be reported as cash outflows either from investing activities or operating activities. AFG has elected to show all corporate-owned life insurance activity in investing activities. Prior to adoption of this guidance, AFG accounted for these transactions as operating activities. In addition, ASU 2016-15 clarifies when distributions received from investees accounted under the equity method should be accounted for as a cash inflow from operating activities or as a cash inflow from investing activities. AFG had previously accounted for all distributions from investments accounted for under the equity method as investing activities. The new guidance solely related to the presentation of certain transactions in the statement of cash flows. Accordingly, adoption of this guidance did not impact AFG’s results of operations or financial position.
Revenue Recognition Guidance Effective in 2018 In May 2014, the FASB issued ASU 2014-09, which requires an entity to recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. Revenue is recognized when (or as) the entity satisfies a performance obligation under the contract. The new guidance also updates the accounting for certain costs associated with obtaining and fulfilling contracts with customers and requires disclosures regarding the nature, amount, timing and uncertainty of revenue and cash flows arising from contracts with customers. Revenue recognition for insurance contracts and financial instruments, which are AFG’s primary sources of revenue, is excluded from the scope of the new guidance. AFG will adopt the new guidance effective January 1, 2018. Because the new guidance would have applied to 2% of AFG’s 2017 consolidated revenues and the impact of the new guidance on the recognition of those revenues would not have been material, management does not expect the new guidance to have a material impact on AFG’s results of operations and financial position.

B. Acquisitions and Sale of Businesses
Neon Lloyd’s Business On December 29, 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 L — “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.
Acquisition of Noncontrolling Interest in National Interstate Corporation On November 10, 2016, AFG acquired the 49% of National Interstate Corporation (“NATL”) not previously owned by AFG’s wholly-owned subsidiary, Great American Insurance Company for $315 million ($32.00 per share) in a merger transaction. In addition, NATL paid a one-time special cash dividend of $0.50 per share to its shareholders immediately prior to the merger closing ($5 million was paid to noncontrolling shareholders). Expenses related to the merger were approximately $10 million and were expensed as incurred.
Because NATL was already a consolidated subsidiary of AFG prior to the merger, the acquisition was accounted for as an equity transaction. As a result, the excess of the consideration paid over the carrying value of the noncontrolling interest acquired was recorded as a $137 million reduction in AFG’s Capital Surplus. In addition, the merger allowed NATL and its subsidiaries to become members of the AFG consolidated tax group, which resulted in a tax benefit of $66 million in the fourth quarter of 2016.
Sale of Long-term Care Business In December 2015, AFG completed the sale of substantially all of its run-off long-term care insurance business (which was included in the run-off long-term care and life segment) 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 the future 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. The legal entities involved in the transaction, United Teacher Associates Insurance Company (“UTA”) and Continental General Insurance Company (“CGIC”), 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 business. Following the sale of these subsidiaries, AFG has only a small block of long-term care insurance (1,600 policies) with approximately $39 million in reserves at December 31, 2017. AFG had ceased new sales of long-term care insurance in January 2010, but continued to accept renewal premiums on its outstanding policies, which are guaranteed renewable.
In addition to the net proceeds received at closing and the $13 million of potential additional proceeds in the future from the release of statutory liabilities, AFG received a total of $97 million in tax benefits in 2016 related to the sale through reduced estimated tax payments and a tax refund resulting from the carryback of the tax-basis capital loss. The receivables for these tax benefits were reflected in AFG’s financial statements at December 31, 2015.
Based on the status of ongoing negotiations at the end of the first quarter of 2015, management determined that the potential sale of the run-off long-term care insurance business met the GAAP “held for sale” criteria as of March 31, 2015. Accordingly, AFG recorded a $162 million pretax loss ($105 million loss after tax) in the first quarter of 2015 to establish a liability equal to the excess of the net carrying value of the assets and liabilities to be disposed over the estimated net sale proceeds. At the closing date, the loss was adjusted to $166 million ($108 million loss after tax) based on the actual proceeds received and the final carrying value of the net assets disposed. In the second quarter of 2016, AFG received additional proceeds based on the final closing balance sheet and adjusted certain accrued expense estimates associated with the sale, resulting in a $2 million pretax gain. At March 31, 2015 and at the sale date, the carrying value of the assets and liabilities disposed represented approximately 4% of both AFG’s assets and liabilities.
Under accounting guidance effective in January 2015, only disposals of components of an entity that represent a strategic shift and that have a major effect on a reporting entity’s operations and financial results are reported as discontinued operations. Due to the run-off nature of the business and the immaterial expected impact on AFG’s results of operations, the sale of AFG’s long-term care insurance business has not been reported as a discontinued operation.

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, trucks and recreational vehicles, inland and ocean marine, agricultural-related products and other property coverages, (ii) Specialty casualty, which includes primarily excess and surplus, general liability, executive liability, professional liability, umbrella and excess liability, specialty coverage 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 leasing and financing institutions (including collateral and lender-placed mortgage property insurance), surety and fidelity 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 markets traditional fixed and fixed-indexed annuities in the retail, financial institutions and education 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 5% of AFG’s revenues in 2017 and 4% of AFG’s revenues in 2016 and 2015.

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 and 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, mortgage-backed securities (“MBS”) 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. AFG’s Level 3 is comprised of 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.
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 25 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.

Transfers between Level 1 and Level 2 for all periods presented were a result of increases or decreases in observable trade activity.
Approximately 5% of the total assets carried at fair value on December 31, 2017, were Level 3 assets. Approximately 79% ($1.80 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. Since internally developed Level 3 asset fair values represent less than 10% of AFG’s Shareholders’ Equity, any justifiable changes in unobservable inputs used to determine internally developed fair values would not have a material impact on AFG’s financial position.
The only significant Level 3 assets or liabilities carried at fair value in the financial statements that were not measured using broker quotes are the derivatives embedded in AFG’s fixed-indexed annuity liabilities, which are measured using a discounted cash flow approach and had a fair value of $2.54 billion at December 31, 2017. The following table presents information about the unobservable inputs used by management in determining fair value of these embedded derivatives. See Note F — “Derivatives.”

| Unobservable Input |  | Range |
| Adjustment for insurance subsidiary’s credit risk |  | 0.2% – 2.0% over the risk free rate |
| Risk margin for uncertainty in cash flows |  | 0.70% reduction in the discount rate |
| Surrenders |  | 3% – 23% of indexed account value |
| Partial surrenders |  | 2% – 10% of indexed account value |
| Annuitizations |  | 0.1% – 1% of indexed account value |
| Deaths |  | 1.6% – 8.0% of indexed account value |
| Budgeted option costs |  | 2.4% – 3.6% of indexed account value |

The range of adjustments for insurance subsidiary’s credit risk 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 annuity products with an expected range of 6% to 10% in the majority of future calendar years (3% to 23% 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 annuity embedded derivatives, while increasing any of the other unobservable inputs in the table above would decrease the fair value of the embedded derivatives.

(*) | Excludes $206 million and $204 million of life contingent annuities in the payout phase at December 31, 2017 and 2016, respectively.

The carrying amount of cash and cash equivalents approximates fair value. Fair values for mortgage loans are estimated by discounting the future contractual cash flows using the current rates at which similar loans would be made to borrowers with similar credit ratings. The fair value of policy loans is estimated to approximate carrying value; policy loans have no defined maturity dates and are inseparable from insurance contracts. The fair value of annuity benefits was estimated based on expected cash flows discounted using forward interest rates adjusted for the Company’s credit risk and includes the impact of maintenance expenses and capital costs. Fair values of long-term debt are based primarily on quoted market prices.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — CONTINUED
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 dividend 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 2017, AFG recorded $1 million in other-than-temporary impairment charges related to its residential MBS.
In 2017, AFG recorded approximately $19 million and $4 million in other-than-temporary impairment charges related to other fixed maturities (other than residential MBS securities) and other investments, respectively.
AFG recorded $55 million in other-than-temporary impairment charges on common stocks in 2017. At December 31, 2017, the gross unrealized losses on common stocks of $22 million relate to 16 securities, none of which has been in an unrealized loss position for more than 12 months.
AFG recorded $9 million in other-than-temporary impairment charges on preferred stock in 2017. At December 31, 2017, the gross unrealized losses on preferred stocks of $1 million relate to 7 securities. Three preferred stocks have been in an unrealized loss position for 12 months or more and all are investment grade rated.
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, 2017. As discussed in Note A — “Accounting Policies — Investments,” effective January 1, 2018, all equity securities currently classified as “available for sale” will be required to be carried at fair value through net earnings instead of accumulated other comprehensive income and will therefore no longer be evaluated for other-than-temporary impairment.
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):

Net Unrealized Gain on Marketable Securities In addition to adjusting fixed maturity securities and equity 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.

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, 2017 |  | December 31, 2016
Derivative |  | Balance Sheet Line |  | Asset |  | Liability |  | Asset |  | Liability
MBS with embedded derivatives |  | Fixed maturities |  | $ | 105 |  |  | $ | — |  |  | $ | 107 |  |  | $ | — |
Public company warrants |  | Equity securities |  | 4 |  |  | — |  |  | 4 |  |  | — |
Fixed-indexed annuities (embedded derivative) |  | Annuity benefits accumulated |  | — |  |  | 2,542 |  |  | — |  |  | 1,759 |
Equity index call options |  | Equity index call options |  | 701 |  |  | — |  |  | 492 |  |  | — |
Reinsurance contract (embedded derivative) |  | Other liabilities |  | — |  |  | 4 |  |  | — |  |  | 8 |
|  |  |  | $ | 810 |  |  | $ | 2,546 |  |  | $ | 603 |  |  | $ | 1,767 |

The MBS with embedded derivatives consist primarily of interest-only MBS with interest rates that float inversely with short-term rates. 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 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 of call options on the appropriate index. AFG receives collateral from certain of its counterparties to support its purchased call option assets. This collateral ($389 million at December 31, 2017 and $380 million at December 31, 2016) 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 change in the fair value of the call option assets 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 options are considered derivatives. Fluctuations in interest rates and the stock market, among other factors, can cause volatility in the periodic measurement of fair value of the embedded derivative that management believes can be inconsistent with the long-term economics of these products.
As discussed under “Reinsurance” in Note A, AFG has a reinsurance contract that is considered to contain an embedded derivative.

Derivatives Designated and Qualifying as Cash Flow Hedges As of December 31, 2017, AFG has entered into ten 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 August 2019 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 increased to $1.58 billion at December 31, 2017 compared to $1.08 billion at December 31, 2016, reflecting three new swaps with an aggregate notional amount at issuance of $663 million entered into in 2017, partially offset by the scheduled amortization discussed above. The fair value of the effective portion of the interest rate swaps in an asset position and included in other assets was less than $1 million at December 31, 2017 and $1 million at December 31, 2016. The fair value of the effective portion of interest rate swaps in a liability position and included in other liabilities was $31 million at December 31, 2017 and $22 million at December 31, 2016. 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 $6 million in 2017, $7 million in 2016 and $6 million in 2015. There was no ineffectiveness recorded in net earnings during these periods. A collateral receivable supporting these swaps of $70 million at December 31, 2017 and $60 million at December 31, 2016 is included in other assets in AFG’s Balance Sheet.
Derivative Designated and Qualifying as a Fair Value Hedge In June 2015, AFG entered into an interest rate swap to mitigate the interest rate risk associated with its fixed-rate 9-7/8% Senior Notes due June 2019 by effectively converting the interest rate on those notes to a floating rate of three-month LIBOR plus 8.099%. In connection with redemption of the 9-7/8% Senior Notes in December 2017, AFG paid the counterparty $1 million to settle the interest rate swap.
Since the terms of the interest rate swap matched the terms of the hedged debt, changes in the fair value of the interest rate swap were offset by changes in the fair value of the hedged debt attributable to changes in interest rates. The fair value of the interest rate swap (asset of $1 million at December 31, 2016) and the offsetting adjustment to the carrying value of the 9-7/8% Senior Notes were both included in long-term debt on AFG’s Balance Sheet. Accordingly, the net impact on AFG’s earnings during the period that the swap was outstanding was that the interest expense associated with the hedged debt was effectively recorded at the floating rate. The net reduction in interest expense from the swap for 2017, 2016 and 2015 was $2 million, $3 million and $2 million, respectively.

(*) | Unrealized adjustments to DPAC includes net unrealized gains/losses on securities and net unrealized gains/losses on cash flow hedges.

The present value of future profits (“PVFP”) amounts in the table above are net of $141 million and $134 million of accumulated amortization at December 31, 2017 and 2016, 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 fifteen collateralized loan obligation entities or “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 2004 and 2017, 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 particular 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 its CLOs is limited to its investment in the CLOs, which had an aggregate fair value of $215 million (including $130 million invested in the most subordinate tranches) at December 31, 2017, and $216 million at December 31, 2016.
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. During 2017, AFG subsidiaries received $103 million in sale and redemption proceeds from its CLO investments. In 2016, AFG formed two new CLOs, which issued an aggregate of $866 million face amount of liabilities (including $64 million face amount purchased by subsidiaries of AFG). During 2016, AFG subsidiaries also purchased $24 million face amount of senior debt and subordinate tranches of existing CLOs for $17 million. During 2016, AFG subsidiaries also received $115 million in sale and redemption proceeds from its CLO investments. In 2015, AFG formed two new CLOs, which issued an aggregate of $869 million face amount of liabilities (including $81 million face amount purchased by subsidiaries of AFG). In 2017, two AFG CLOs 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):

The aggregate unpaid principal balance of the CLOs’ fixed maturity investments exceeded the fair value of the investments by $55 million and $75 million at December 31, 2017 and 2016. The aggregate unpaid principal balance of the CLOs’ debt exceeded its carrying value by $118 million and $159 million at those dates. The CLO assets include loans with an aggregate fair value of $1 million at both December 31, 2017 and December 31, 2016, for which the CLOs are not accruing interest because the loans are in default (aggregate unpaid principal balance of $8 million and $10 million at those dates, respectively).
I. Goodwill and Other Intangibles
Changes in the carrying value of goodwill during 2015, 2016 and 2017, by reporting segment, are presented in the following table (in millions):

| Property and Casualty |  | Annuity |  | Total
Balance at January 1, 2015 | $ | 168 |  |  | $ | 33 |  |  | $ | 201 |
Sale of subsidiaries in 2015 | — |  |  | (2 | ) |  | (2 | )
Balance at December 31, 2015, December 31, 2016 and December 31, 2017 | $ | 168 |  |  | $ | 31 |  |  | $ | 199 |

Goodwill decreased by $2 million in the fourth quarter of 2015 due to the sale of UTA and CGIC as discussed in Note B — “Acquisitions and Sale of Businesses.”

Included in other assets in AFG’s Balance Sheet is $26 million at December 31, 2017 and $34 million at December 31, 2016 of amortizable intangible assets related to property and casualty insurance acquisitions. These amounts are net of accumulated amortization of $30 million and $25 million, respectively. Amortization of intangibles was $8 million in each of 2017, 2016 and 2015. Future amortization of intangibles (weighted average amortization period of 3 years) is estimated to be $8 million per year in each of 2018 through 2020 and $2 million in 2021.

At December 31, 2017, scheduled principal payments on debt for the subsequent five years and thereafter were as follows: 2018 — none; 2019 — none; 2020 — none; 2021 — none; 2022 — none and thereafter — $1.32 billion.
In June 2017, AFG issued $350 million in 4.50% Senior Notes due in 2047 at a price of 99.46%. The net proceeds of the offering were used to redeem AFG’s $230 million outstanding principal amount of 6-3/8% Senior Notes due June 2042 at par value and to redeem AFG’s $125 million outstanding principal amount of 5-3/4% Senior Notes due August 2042 at par value in June 2017 and August 2017, respectively.
In November 2017, AFG issued an additional $125 million of 3.50% Senior Notes due in 2026 at a price of 99.698% and $240 million of 4.50% Senior Notes due in 2047 at a price of 102.374%. 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 August 2016, AFG issued $300 million in 3.50% Senior Notes due in 2026 at a price of 99.608%. The net proceeds of the offering were used to fund a portion of the November 2016 acquisition of the noncontrolling interest in NATL (discussed in Note B — “Acquisitions and Sale of Businesses”). At the acquisition date, the $18 million outstanding under NATL’s bank credit facility, including $6 million borrowed in September 2016, was repaid and the credit agreement was terminated.
In September 2015, AFG used cash on hand to redeem the $132 million in outstanding AFG 7% Senior Notes due September 2050 at par value. In November 2015, AFG issued $150 million in 6% Subordinated Debentures due in 2055. During 2015, subsidiaries of AFG repaid all of the outstanding notes secured by real estate.
To achieve a desired balance between fixed and variable rate debt, AFG entered into an interest rate swap in June 2015, which effectively converted its 9-7/8% Senior Notes to a floating rate of three-month LIBOR plus 8.099%. In December 2017, AFG settled the interest rate swap contemporaneously with the redemption of the 9-7/8% Senior Notes. At December 31, 2016, the fair value of the interest rate swap (asset of $1 million at that date) and the offsetting adjustment to the carrying value of the notes were both included in the carrying value of the 9-7/8% Senior Notes in the table above.

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, 2017 or December 31, 2016.
Cash interest payments on long-term debt were $85 million in 2017, $75 million in 2016 and 2015. In 2017, 2016 and 2015, AFG received $2 million, $3 million and $2 million, respectively, in interest under the interest rate swap discussed above.
K. Shareholders’ Equity
AFG is authorized to issue 12.5 million shares of Voting Preferred Stock and 12.5 million shares of Nonvoting Preferred Stock, each without par value.
Stock Incentive Plans Under AFG’s stock incentive plans, employees of AFG and its subsidiaries are eligible to receive equity awards in the form of stock options, stock appreciation rights, restricted stock awards, restricted stock units and stock awards. At December 31, 2017, there were 8.0 million shares of AFG Common Stock reserved for issuance under AFG’s stock incentive plans.
The restricted Common Stock that AFG has granted generally vests over a three or four year period. Data relating to grants of restricted stock is presented below:

| Shares |  | Average Grant Date Fair Value
Outstanding at January 1, 2017 | 678,875 |  |  | $ | 60.90 |
Granted | 232,250 |  |  | $ | 94.44 |

AFG did not grant any stock options in 2017 or 2016. Options granted in years prior to 2016 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, 2017 | 4,505,101 |  |  | $ | 43.02 |  |  |  |  |
Exercised | (1,020,986 | ) |  | $ | 33.38 |  |  |  |  |
Forfeited/Cancelled | (16,775 | ) |  | $ | 55.82 |  |  |  |  |
Outstanding at December 31, 2017 | 3,467,340 |  |  | $ | 45.80 |  |  | 4.9 years |  | $ | 218 |
Options exercisable at December 31, 2017 | 2,589,277 |  |  | $ | 42.00 |  |  | 4.4 years |  | $ | 172 |

The total intrinsic value of options exercised during 2017, 2016 and 2015 was $65 million, $38 million and $52 million, respectively.

AFG used the Black-Scholes option pricing model to calculate the fair value of its option grants issued during 2015 (no options were granted in 2016 or 2017). The expected dividend yield is based on AFG’s current dividend rate. To determine expected volatility, AFG considers its daily historical volatility as well as implied volatility on traded options. The expected term was estimated based on historical exercise patterns and post vesting cancellations. The risk-free rate for periods associated with the expected term is based upon the U.S. Treasury yield curve in effect on the grant date.

| 2015
Exercise price | $ | 63.15 |
Expected dividend yield | 1.6 | %
Expected volatility | 25 | %
Expected term (in years) | 7.25 |
Risk-free rate | 1.88 | %
Grant date fair value | $ | 15.29 |

Total compensation expense related to stock incentive plans of AFG and its subsidiaries for 2017, 2016 and 2015 was $30 million, $28 million and $27 million, respectively. AFG’s provision for income tax includes tax benefits of $27 million in 2017, $19 million in 2016 and $8 million in 2015 related to AFG’s stock incentive plans. The tax benefit of $27 million in 2017 and $19 million in 2016 includes $17 million and $9 million, respectively, that under the previous guidance would have been recorded directly to capital surplus. At December 31, 2017, there was $7 million and $31 million of unrecognized compensation expense related to nonvested stock options and restricted stock awards, respectively. The nonvested stock options and restricted stock awards amounts are expected to be recognized over a weighted average of 1.7 years and 2.6 years, respectively.

The favorable impact of stock-based compensation on AFG’s effective tax rate in the year ended December 31, 2017 reflects the high volume of employee stock option exercises during that period and the increase in the market price of AFG Common Stock.
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 related to the change in the U.S. corporate tax rate is included in “Change in U.S. corporate tax rate” in table above.
In connection with the reorganization of the Neon Lloyd’s business, in December 2016, AFG undertook a restructuring that included the liquidation for tax purposes of the foreign subsidiary that is the parent of the Neon Lloyd’s operations, resulting in a taxable loss for U.S. tax purposes. AFG reported a $111 million tax benefit associated with this loss in the fourth quarter of 2016. Approximately $29 million of the $111 million tax benefit recorded in 2016 reduced current taxes payable for 2016, while the remaining tax benefit was received in 2017 from the carry-back of the tax-basis capital loss to offset capital gains in prior years. An additional loss associated with the 2016 restructuring was deferred under U.S. tax laws, resulting in an unrecognized potential tax benefit of $48 million at December 31, 2016. The sale of the noncontrolling interest in Neon resulted

AMERICAN FINANCIAL GROUP, INC. AND SUBSIDIARIES
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — CONTINUED
in the recognition of an additional tax benefit of $56 million in the fourth quarter of 2017, including the recognition of the deferred loss from the 2016 restructuring. Approximately $20 million of the $56 million tax benefit recorded in 2017 reduced current taxes payable for 2017, while the majority of the remaining tax benefit will be received in 2018 from the carry-back of the tax basis capital loss to offset capital gains in prior years.
The Tax Cuts and Jobs Act of 2017 (“TCJA”), which lowers the U.S corporate tax rate to 21% and makes other widespread changes to the U.S. tax code beginning in 2018, was enacted on December 22, 2017. 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.
The TCJA is subject to further clarification and interpretation by the U.S. Treasury Department and the Internal Revenue Service. For example, the TCJA changes the way that companies calculate their insurance claims and reserves for tax purposes, including revaluing those tax basis liabilities as of January 1, 2018, based on a methodology and discount factors that have not been published. The resulting transitional deferred tax liability (taxes payable over eight years under the TCJA) and offsetting increase in AFG’s insurance claims and reserves deferred tax assets, were recorded at December 31, 2017 using reasonable estimates based on available information and should be considered provisional in accordance with Securities and Exchange Commission Staff Accounting Bulletin No. 118 (“SAB 118”). Because the established transition liability was completely offset by an increase in related deferred tax assets, any adjustment to the provisional amount will not impact AFG’s effective tax rate. In accordance with SAB 118, the insurance claims and reserves transitional deferred tax liability (and offsetting adjustment to the related deferred tax assets) and any other changes in deferred taxes resulting from clarification and interpretation of the TCJA provided during 2018 will be recorded in the period in which the guidance is published.
As discussed in Note B — “Acquisitions and Sale of Businesses,” AFG acquired the noncontrolling interest in NATL in November 2016. This transaction allowed NATL and its subsidiaries to become members of the AFG consolidated tax group, which resulted in a tax benefit of $66 million to AFG during the fourth quarter of 2016.
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%. Excluding a $65 million charge related to the exit of certain lines of business within Neon and the tax benefits related to the acquisition of the noncontrolling interest in NATL and the Neon restructuring, AFG’s effective tax rate for the year ended December 31, 2016 was 35%.
AFG’s 2012 — 2017 tax years remain subject to examination by the IRS.
Total earnings before income taxes include losses subject to tax in foreign jurisdictions of $58 million in 2017, $160 million in 2016 and $66 million in 2015, 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, 2017 and 2016 is included in other assets in AFG’s Balance Sheet. The decrease in AFG’s net deferred tax asset at December 31, 2017 compared to December 31, 2016 reflects the impact of the change in the U.S. corporate tax rate, partially offset by 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 include 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 $80 million against these deferred tax assets at December 31, 2017. 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 $27 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 $13 million of AFG’s SRLY NOLs expired unutilized at December 31, 2017. 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.

The total unrecognized tax benefits and related interest and penalties that, if recognized, would impact the effective tax rate is less than $1 million at December 31, 2017 and December 31, 2016. AFG’s provision for income taxes included a benefit of less than $1 million in 2017 and an expense of less than $1 million in 2016 and 2015 of interest (net of federal benefit or expense). AFG’s liability for interest related to unrecognized tax benefits was less than $1 million at December 31, 2017 and December 31, 2016 (net of federal benefit). AFG’s provision for income taxes in 2017 and 2016 included penalties of less than $1 million; no penalties were recorded in 2015. AFG’s liability for penalties related to unrecognized tax benefits was less than $1 million at December 31, 2017 and December 31, 2016.
Cash payments for income taxes, net of refunds, were $194 million, $308 million and $234 million for 2017, 2016 and 2015, respectively.
M. 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 a comprehensive external study of its asbestos and environmental (“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. AFG completed an in-depth internal review of its A&E exposures in the third quarter of 2016. The review resulted in special A&E charges of $36 million for the property and casualty group and $5 million for the former railroad and manufacturing operations. AFG completed a comprehensive external study of its A&E exposures in the third quarter of 2015 with the aid of specialty actuarial, engineering and consulting firms and outside counsel. The study resulted in special A&E charges of $67 million for the property and casualty group and $12 million for the former railroad and manufacturing operations.
The property and casualty group’s liability for A&E reserves was $528 million at December 31, 2017; related recoverables from reinsurers (net of allowances for doubtful accounts) at that date were $125 million.
At December 31, 2017, American Premier and its subsidiaries had liabilities for environmental and personal injury claims and other contingencies aggregating $81 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, 2017, GAFRI had a liability of $8 million for environmental costs and certain other matters associated with the sales of its former manufacturing operations.

See Note B — “Acquisitions and Sale of Businesses” for a discussion of the five-year capital maintenance agreement that AFG entered into in connection with obtaining regulatory approval for the sale of substantially all of its run-off long-term care insurance business in December 2015.
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.
N. 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, 2017 (in millions, except per share amounts). Quarterly earnings per share do not add to year-to-date amounts due to changes in shares outstanding.

Pretax realized gains on subsidiaries and securities (including other-than-temporary impairments), favorable (adverse) prior year development of AFG’s liability for losses and loss adjustment expenses (“LAE”) and the impact of derivatives related to FIAs were as follows (in millions):

Adverse prior year development for the third quarters of 2017 and 2016 include pretax special charges of $89 million and $36 million, respectively, to strengthen property and casualty insurance A&E reserves. As a result of the Neon reinsurance to close agreement discussed in Note O — “Insurance,” Neon recorded $42 million in favorable development in the fourth quarter of 2017, of which $24 million related to its ongoing lines of business and $18 million related to its exited lines of business. During the second quarter of 2016, AFG recorded a pretax charge of $65 million related to Neon’s claims review of its exited lines of business, including $57 million to increase loss reserves primarily related to its medical malpractice and general liability classes.
Fixed-indexed annuities (“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 of call options on the appropriate index. AFG’s strategy is designed so that the change in the fair value of the call option assets 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 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 fair value of the embedded derivative that management believes can be inconsistent with the long-term economics of these products. In the table above, the impact of changes in the fair value of the derivatives related to FIAs is presented net of an estimate of the related acceleration/deceleration of the amortization of deferred policy acquisition costs and deferred sales inducements.
AFG’s property and casualty operations recorded catastrophe losses totaling $140 million in 2017, including $107 million in the third quarter (primarily from Hurricanes Harvey, Irma and Maria and earthquakes in Mexico). Catastrophe losses for 2016 totaling $55 million were spread somewhat evenly across the four quarters.
Results include pretax gains (included in other income) of $13 million from the sale of a hotel in the first quarter of 2017 and$32 million from the sale of an apartment property in the second quarter of 2016.
Results for the third quarter of 2017 and 2016 include pretax special charges of $24 million and $5 million, respectively, to strengthen reserves for A&E exposures related to AFG’s former railroad and manufacturing operations.
In 2017, AFG recorded pretax losses on the retirement of debt of $7 million in the second quarter, $4 million in the third quarter and $40 million in the fourth quarter.
Net earnings in the fourth quarter of 2017 includes $56 million in tax benefits related to the Neon restructuring. Net earnings in the fourth quarter of 2016 includes $177 million in tax benefits related to the NATL merger and Neon restructuring. See Note L — “Income Taxes.”

O. Insurance
Cash and securities owned by U.S.-based insurance subsidiaries, having a carrying value of approximately $1.08 billion at December 31, 2017, were on deposit as required by regulatory authorities. In addition, $205 million was on deposit in support of AFG’s underwriting activities at Lloyd’s. At December 31, 2017, AFG and its subsidiaries had $447 million in undrawn letters of credit (none of which was collateralized) 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, 2017 and 2016, 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 $15 million and $16 million at December 31, 2017 and 2016, 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 2016 reinsurance to close transactions at Neon (discussed below).

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).
The net increase in the provision for claims of prior years in 2016 reflects (i) the $36 million special charge to increase asbestos and environmental reserves, (ii) reserve strengthening at National Interstate and higher than expected claim frequency in the ocean marine business (within the Property and transportation sub-segment), (iii) adverse reserve development at Neon, higher than anticipated severity in New York contractor claims, higher than anticipated claim frequency and severity in general liability insurance and higher than expected claim frequency and severity in the targeted markets business (within the Specialty casualty sub-segment) and (iv) the $57 million special charge to increase loss reserves related to Neon’s exit of its UK and international medical malpractice and general liability lines of business. This adverse development was partially offset by (i) lower than expected losses in the crop business and lower than expected claim severity in the property and inland marine and trucking businesses (all within the Property and transportation sub-segment), (ii) lower than anticipated claim frequency and severity in workers’ compensation business, lower than expected claim severity in directors and officers liability insurance and lower than expected claim frequency and severity in excess liability business (all within the Specialty casualty sub-segment) and (iii) lower than anticipated claim severity in the fidelity and crime business, lower than expected claim frequency and severity in the surety business and lower than anticipated claim frequency in the financial institutions business (within the Specialty financial sub-segment).
The net increase in the provision for claims of prior years in 2015 reflects (i) the $67 million special charge to increase asbestos and environmental reserves, (ii) higher than expected claim severity at National Interstate and higher than anticipated claim frequency in the ocean marine business (all within the Property and transportation sub-segment) and (iii) adverse reserve development at Neon (within the Specialty casualty sub-segment). This adverse development was partially offset by (i) lower than expected claim severity in the property and inland marine business, agricultural operations and a run-off book of homebuilders business (all within the Property and transportation sub-segment), (ii) lower than anticipated claim severity in workers’ compensation business, lower than anticipated claim severity and frequency in excess liability insurance and lower than expected claim severity in directors and officers liability insurance (all within the Specialty casualty sub-segment), and (iii) lower than anticipated claim frequency and severity in the surety business and products for financial institutions and lower than expected claim severity in the fidelity business and run-off collateral value insurance (all within the Specialty financial 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 will be effective as of December 31, 2017. 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 provides 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 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 (discussed below and included in Neon exited lines charge). In November 2016, the Neon Lloyd’s syndicate completed a similar reinsurance to close transaction with StarStone, which covered liabilities relating to the syndicate’s 2007 and prior years of account. That transaction also included a quota share of the Italian public hospital business written in Neon’s 2008 year of account and represented Neon’s complete exit from the Italian public hospital medical malpractice business.
In May 2015, the FASB issued ASU 2015-09, Financial Services-Insurance: Disclosures about Short-Duration Contracts. The ASU requires insurance entities to disclose incurred and paid claims development information by accident year, net of reinsurance. All of AFG’s material short-duration insurance contracts are written in its property and casualty insurance segment. The development tables and the associated disclosures are aggregated in the following Specialty sub-segments: Property and transportation, Specialty casualty, Specialty financial and Other specialty. See Note C — “Segments of Operations” to the financial statements for a discussion of these sub-segments.

Closed Block of Long-Term Care Insurance Following the completion of the sale of substantially all of its run-off long-term care insurance business in December 2015, AFG’s remaining long-term care insurance reserves were $39 million at December 31, 2017 and $37 million at December 31, 2016, 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 $44 million investment in FHLB capital stock at December 31, 2017, 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 the fourth quarter of 2017, GALIC refinanced the terms on advances totaling $831 million, which lowered the spread over LIBOR. In the fourth quarter of 2017, GALIC also repaid $64 million to the FHLB, decreasing the total amount advanced to $871 million (included in annuity benefits accumulated) at December 31, 2017. Interest rates under the various funding agreements on the advances range from 0.03% to 0.35% over LIBOR (average rate of 1.75% at December 31, 2017). While these advances must be repaid between 2018 and 2020 ($285 million in 2018 and $586 million in 2020), 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 $1.04 billion (included in available for sale fixed maturity securities) at December 31, 2017. Interest credited on the funding agreements, which is included in annuity benefits, was $14 million in 2017, $8 million in 2016 and $3 million in 2015.
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
| 2017 |  | 2016 |  | 2015 |  | 2017 |  | 2016
Property and casualty companies | $ | 484 |  |  | $ | 461 |  |  | $ | 408 |  |  | $ | 2,729 |  |  | $ | 2,939 |
Life insurance companies | 286 |  |  | 167 |  |  | 399 |  |  | 2,132 |  |  | 1,976 |

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, 2017 and 2016, 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, 2017 or 2016.
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 2018 from its insurance subsidiaries without seeking regulatory approval is $826 million. Additional amounts of dividends require regulatory approval.
AFG paid common stock dividends to shareholders totaling $421 million, $187 million and $178 million in 2017, 2016 and 2015, 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, 2017, AFG could pay dividends in excess of $1 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 $100 million (per occurrence and annual aggregate) occurring between June 1, 2017 and 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, 2017, 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’s property and casualty insurance operations entered into a similar reinsurance agreement in March 2014 to obtain additional catastrophe protection through a catastrophe bond structure with Riverfront, which provided supplemental reinsurance coverage for catastrophe losses occurring between April 1, 2014 and January 6, 2017.
AFG has reinsured approximately $8.32 billion of its $12.05 billion in face amount of life insurance at December 31, 2017 compared to $10.22 billion of its $13.49 billion in face amount of life insurance at December 31, 2016. Life written premiums ceded were $28 million, $31 million and $40 million for 2017, 2016 and 2015, respectively. Reinsurance recoveries on ceded life policies were $35 million, $41 million and $50 million for 2017, 2016 and 2015, 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 (“EDAR”), 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):

| 2017 |  | 2016
Expected death and annuitization | $ | 228 |  |  | $ | 223 |
Guaranteed withdrawal benefits | 357 |  |  | 278 |
Accrued persistency and premium bonuses | 3 |  |  | 6 |

Variable Annuities At December 31, 2017, 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 $15 million, compared to $20 million at December 31, 2016. Death benefits paid in excess of the variable annuity account balances were less than $1 million in each of the last three years.

P. Additional Information
Allowance for Uncollectible Reinsurance AFG’s aggregate allowance for uncollectible reinsurance recoverables was $20 million at December 31, 2017 and $22 million at December 31, 2016. 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 both 2017 and 2016 and $3 million in 2015. In 2017, the allowance was reduced by reinsurance recoverable write-offs of $2 million.
Operating Leases Total rental expense for various leases of office space and equipment was $69 million in 2017, $67 million in 2016 and $70 million in 2015. Future minimum rentals, related principally to office space, required under operating leases having initial or remaining noncancelable lease terms in excess of one year at December 31, 2017, were as follows: 2018 – $63 million; 2019 – $57 million; 2020 – $50 million; 2021 – $42 million; 2022 – $34 million; and $100 million thereafter.
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, 2017, AFG and its subsidiaries had commitments to fund credit facilities and contribute capital to limited partnerships and limited liability corporations of approximately $484 million.
Benefit Plans AFG expensed approximately $45 million in 2017, $43 million in 2016 and $34 million in 2015 for its retirement and employee savings plans.
