Property and Casualty Insurance

Property and Casualty Insurance Segment — Results of Operations

AFG’s property and casualty insurance operations contributed $1.33 billion in GAAP pretax earnings in 2024 compared to $1.30 billion in 2023, an increase of $28 million (2%). Property and casualty core pretax earnings were $1.33 billion in 2024 compared to $1.30 billion in 2023, an increase of $24 million (2%). The increase in GAAP and core pretax earnings in 2024 compared to 2023 reflects higher investment income outside of alternative investments, partially offset by lower investment income from AFG’s alternative investment portfolio (partnerships and similar investments and AFG-managed CLOs) and lower underwriting profit.

AFG’s property and casualty insurance operations contributed $1.30 billion in GAAP pretax earnings in 2023 compared to $1.42 billion in 2022, a decrease of $119 million (8%). Property and casualty core pretax earnings were $1.30 billion in 2023 compared to $1.42 billion in 2022, a decrease of $115 million (8%). The decrease in GAAP and core pretax earnings reflects lower underwriting profit and lower investment income from alternative investments, partially offset by higher investment income outside of alternative investments in 2023 compared to 2022.

The following table details AFG’s GAAP and core earnings before income taxes from its property and casualty insurance operations for the years ended December 31, 2024, 2023 and 2022 (dollars in millions):

The $877 million (9%) increase in gross written premiums in 2024 compared to 2023 reflects growth in each of the Specialty property and casualty sub-segments as a result of additional crop premiums from the CRS acquisition in the Property and transportation sub-segment and new business opportunities, increased exposures and a good renewal rate environment. Overall average renewal rates increased approximately 7% in 2024. Excluding the workers’ compensation businesses, renewal pricing increased approximately 8%.

The $599 million (7%) increase in gross written premiums in 2023 compared to 2022 reflects growth in each of the Specialty property and casualty sub-segments as a result of a combination of new business opportunities, increased exposures and a good renewal rate environment. Overall average renewal rates increased approximately 5% in 2023. Excluding the workers’ compensation businesses, renewal pricing increased approximately 6%.

Property and transportation Gross written premiums increased $589 million (14%) in 2024 compared to 2023. Year-over-year premium growth resulted from additional crop premium associated with the CRS acquisition as well as new business opportunities, a favorable rate environment and increased exposures in the commercial auto businesses. This year-over-year premium growth was tempered by the impact of lower year-over-year commodity pricing on winter wheat premiums, coupled with elevated pricing competition and the non-renewal of certain under-performing accounts in the transportation businesses. Excluding crop premium, gross and net written premiums in this group grew by 5% and 4%, respectively. Average renewal rates increased approximately 8% for this group in 2024. Reinsurance premiums ceded as a percentage of gross written premiums increased 3 percentage points in 2024 compared to 2023 reflecting the impact of higher cessions in the crop business and growth in certain programs in the transportation businesses that cede a larger percentage of premiums than some of the other businesses in the Property and transportation sub-segment.

Gross written premiums increased $86 million (2%) in 2023 compared to 2022 reflecting the impact of increased rates, retentions and exposures in the transportation and ocean marine businesses and slightly higher crop premium related to the CRS acquisition in the fourth quarter of 2023. These items were partially offset by the impact of 2023 spring commodity futures pricing and related volatility on premiums in the crop business. Average renewal rates increased approximately 6% for this group in 2023. Reinsurance premiums ceded as a percentage of gross written premiums were comparable in 2023 and 2022 reflecting growth in alternative risk transfer products in the transportation businesses, offset by the impact of lower cessions in the crop business. Both of these businesses cede a larger percentage of premiums than some of the other businesses in the Property and transportation sub-segment.

Specialty casualty Gross written premiums increased $175 million (4%) in 2024 compared to 2023. The higher-year-over-year premiums resulted primarily from growth in the excess and surplus, excess liability and certain targeted markets businesses as a result of rate increases, new business opportunities and strong policy retention. The mergers and acquisitions liability business also benefited from an increase in mergers and acquisition activity. This growth was tempered by lower year-over-year workers’ compensation premiums. Average renewal rates increased approximately 6% for this group in 2024. Excluding overall rate decreases in the workers’ compensation businesses, renewal rates for this group increased approximately 9% in 2024. Reinsurance premiums ceded as a percentage of gross written premiums were comparable in 2024 and 2023 reflecting lower cessions in certain more heavily reinsured products in the social services business, offset by the impact of higher premiums in the excess and surplus and mergers and acquisitions liability businesses, which cede a larger percentage of premiums than some of the other businesses in the Specialty casualty sub-segment and higher cessions in the public sector business.

Gross written premiums increased $253 million (6%) in 2023 compared to 2022 due primarily to increased exposures from payroll growth and new business in the workers’ compensation businesses, new business opportunities, strong policy retention and rate increases in several of the targeted markets businesses and increased exposures and higher renewal rates in the excess and surplus and excess liability businesses. This growth was partially offset by lower premiums in the mergers and acquisitions liability and executive liability businesses. Average renewal rates increased approximately 4% for this group in 2023. Excluding overall rate decreases in the workers’ compensation businesses, renewal rates for this group increased approximately 6% in 2023. Reinsurance premiums ceded as a percentage of gross written premiums decreased 1 percentage point in 2023 compared to 2022 reflecting higher premiums in the workers’ compensation businesses (which cede a lower percentage of premiums than some of the other businesses in the Specialty casualty sub-segment) and lower cessions in the environmental and mergers and acquisitions liability businesses and at ABA Insurance Services.

Specialty financial Gross written premiums increased $113 million (10%) in 2024 compared to 2023. Year-over-year growth in the financial institutions business was partially offset by a decision to pause writing of new intellectual property-related coverage. Average renewal rates increased approximately 6% for this group in 2024. Reinsurance premiums ceded as a percentage of gross written premiums decreased 1 percentage point in 2024 compared to 2023 reflecting lower gross written premiums in the innovative markets business, which cedes a larger percentage of premiums than some of the other businesses in the Specialty financial sub-segment, partially offset by the impact of higher reinstatement premiums paid to reinsurers in the fidelity and surety businesses.

Gross written premiums increased $260 million (29%) in 2023 compared to 2022 due primarily to growth in the financial institutions business. Average renewal rates for this group increased approximately 5% in 2023. Reinsurance premiums ceded as a percentage of gross written premiums decreased 1 percentage point in 2023 compared to 2022 reflecting the impact of reinstatement premiums paid to reinsurers in 2022 related to Hurricane Ian.

Other specialty The amounts shown as reinsurance premiums ceded represent business assumed by AFG’s internal reinsurance program from the operations that make up AFG’s other Specialty property and casualty insurance sub-segments. Reinsurance premiums assumed decreased $22 million (8%) in 2024 compared to 2023 and increased $10 million (4%) in 2023 compared to 2022, reflecting changes in premiums retained, primarily from businesses in the Specialty casualty sub-segment.

The Specialty property and casualty insurance operations generated an underwriting profit of $626 million in 2024 compared to $633 million in 2023, a decrease of $7 million (1%). Higher underwriting profit in the Property and transportation and Specialty financial sub-segments was more than offset by lower underwriting profit in the Specialty casualty sub-segment and higher losses in the business assumed by AFG’s internal reinsurance program. Overall catastrophe losses were $182 million (2.6 points on the combined ratio), including $2 million in net reinstatement premiums, for 2024 compared to catastrophe losses of $165 million (2.5 points), including $3 million in net reinstatement premiums, for 2023.

The Specialty property and casualty insurance operations generated an underwriting profit of $633 million in 2023 compared to $780 million in 2022, a decrease of $147 million (19%).

Specialty casualty Underwriting profit for this group was $340 million in 2024 compared to $375 million in 2023, a decrease of $35 million (9%). Higher year-over-year underwriting profit in the targeted markets businesses was more than offset by lower levels of favorable prior year reserve development in the executive liability business and social inflation driven adverse development in the umbrella and excess business. Catastrophe losses were $32 million (1.1 points on the combined ratio), including $1 million in net reinstatement premiums, in 2024 compared to catastrophe losses of $36 million (1.2 points), including $1 million in net reinstatement premiums, in 2023.

Underwriting profit for this group was $375 million in 2023 compared to $500 million in 2022, a decrease of $125 million (25%). The lower year-over-year underwriting profit was due primarily to lower favorable prior year reserve development in the workers’ compensation businesses and adverse reserve development in the public sector and excess and surplus businesses, partially offset by higher favorable prior year reserve development in the executive liability business. Catastrophe losses were $36 million (1.2 points on the combined ratio), including $1 million in net reinstatement premiums, in 2023 compared to catastrophe losses of $11 million (0.5 points) in 2022.

Specialty financial Underwriting profit for this group was $134 million in 2024 compared to $110 million in 2023, an increase of $24 million (22%).

Catastrophe losses were $81 million (7.8 points on the combined ratio) in 2024 compared to catastrophe losses of $49 million (5.7 points) in 2023.

Underwriting profit for this group was $110 million in 2023 compared to $114 million in 2022, a decrease of $4 million (4%).

This group reported an underwriting loss of $36 million in 2023 compared to $42 million in 2022, a decrease of $6 million (14%), reflecting lower losses in the business assumed by AFG’s internal reinsurance program from the operations that make up AFG’s other Specialty sub-segments. The underwriting loss in 2022 relates primarily to losses from social inflation exposed operations in the Specialty casualty sub-segment. Catastrophe losses were $27 million in 2023 compared to $1 million in 2022.

Current accident year losses and LAE, excluding catastrophe losses

The current accident year loss and LAE ratio, excluding catastrophe losses for AFG’s Specialty property and casualty insurance operations was 61.7% in 2024, 62.4% in 2023 and 62.8% in 2022.

Property and transportation The 0.5 percentage points increase in the loss and LAE ratio for the current year, excluding catastrophe losses in 2024 compared to 2023 reflects growth in the crop business, which has a higher loss and LAE ratio than some of the other businesses in the Property and transportation sub-segment and higher reported claim severity in the commercial auto business, partially offset by the impact of improved profitability in the property and inland marine business.

The 1.1 percentage points decrease in the loss and LAE ratio for the current year, excluding catastrophe losses in 2023 compared to 2022 is due primarily to the impact of elevated large loss activity in the property and inland marine business in 2022 and improved results in certain transportation businesses, partially offset by lower profit in the crop business.

Specialty casualty The 1.2 percentage points decrease in the loss and LAE ratio for the current year, excluding catastrophe losses in 2024 compared to 2023 reflects improved results in the workers’ compensation and targeted markets businesses, partially offset by higher claim severity in the excess and surplus business.

The 1.5 percentage points increase in the loss and LAE ratio for the current year, excluding catastrophe losses in 2023 compared to 2022 reflects anticipated medical cost inflation and the impact of pressure on rates in the workers’ compensation businesses and higher claim severity in certain liability coverages.

Specialty financial The 0.9 percentage points decrease in the loss and LAE ratio for the current year, excluding catastrophe losses in 2024 compared to 2023 reflects growth in the financial institutions business, which has a lower loss and LAE ratio than some of the other businesses in the Specialty financial sub-segment, partially offset by higher reported losses and lower premiums in the fidelity and surety businesses.

The 0.2 percentage points decrease in the loss and LAE ratio for the current year, excluding catastrophe losses in 2023 compared to 2022 reflects lower claim frequency and growth in the financial institutions business, which has a lower loss and LAE ratio than some of the other businesses in the Specialty financial sub-segment, partially offset by higher claim severity in the innovative markets business.

Net prior year reserve development

AFG’s Specialty property and casualty insurance operations recorded net favorable reserve development related to prior accident years of $70 million in 2024 compared to $226 million in 2023 and $289 million in 2022, a decrease of $156 million (69%) and $63 million (22%), respectively.

Property and transportation Net favorable reserve development of $94 million in 2024 reflects lower than anticipated losses in the crop business, lower than expected claim severity in the property and inland marine and aviation businesses and lower than anticipated claim frequency and severity in the ocean marine business.

Net favorable reserve development of $84 million in 2023 reflects lower than anticipated losses in the crop business, lower than expected claim frequency and severity across the transportation businesses and lower than anticipated claim frequency in the property and inland marine and ocean marine businesses and in the Singapore operations.
