Property and Casualty Insurance

Property and Casualty Insurance Segment — Results of Operations

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 AFG’s alternative investment portfolio (partnerships and similar investments and AFG-managed CLOs), partially offset by higher investment income outside of alternative investments in 2023 compared to 2022.

AFG’s property and casualty insurance operations contributed $1.42 billion in GAAP pretax earnings in 2022 compared to $1.39 billion in 2021, an increase of $25 million (2%). Property and casualty core pretax earnings were $1.42 billion in 2022 compared to $1.39 billion in 2021, an increase of $29 million (2%). The increase in GAAP and core pretax earnings reflects higher underwriting profit and higher investment income outside of alternative investments, partially offset by lower investment income from AFG’s alternative investment portfolio and higher other net expenses in 2022 compared to 2021.

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, 2023, 2022 and 2021 (dollars in millions):

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%.

The $1.11 billion (14%) increase in gross written premiums in 2022 compared to 2021 reflects growth in the crop insurance business. Excluding crop, gross and net written premiums increased 8% and 9%, respectively, in 2022 compared to 2021 reflecting increased exposures, new business opportunities and renewal rate increases. Overall average renewal rates increased approximately 5% in 2022. Excluding the workers’ compensation businesses, renewal pricing increased approximately 6%.

Property and transportation 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 premiums 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.

Gross written premiums increased $797 million (24%) in 2022 compared to 2021 reflecting the impact of higher commodity futures prices on the crop insurance business. Excluding crop, gross and net written premiums grew 11% and 10%, respectively, reflecting new business opportunities, increased exposures and rate increases. Average renewal rates increased approximately 6% for this group in 2022. Reinsurance premiums ceded as a percentage of gross written premiums increased 4 percentage points in 2022 compared to 2021 reflecting growth in crop insurance products with higher cessions and higher cessions in the ocean marine business.

Specialty casualty 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.

Gross written premiums increased $225 million (6%) in 2022 compared to 2021 due primarily to increased exposures in the excess and surplus businesses, rate increases and new business opportunities in the targeted markets businesses and increased exposures resulting from payroll growth and new business in the workers’ compensation businesses. This premium growth was partially offset by lower year-over-year premiums in the mergers and acquisitions liability business. Average renewal rates increased approximately 5% for this group in 2022. Excluding overall rate decreases in the workers’ compensation businesses, renewal rates for this group increased approximately 7% in 2022. Reinsurance premiums ceded as a percentage of gross written premiums decreased 1 percentage point in 2022 compared to 2021 reflecting lower cessions in the excess and surplus and excess liability businesses and lower gross written premiums in the mergers and acquisitions liability business, which cedes a larger percentage of premiums than the other businesses in the Specialty casualty sub-segment.

Specialty financial Gross written premiums increased $260 million (29%) in 2023 compared to 2022 due primarily to growth in the financial institutions business. Average renewal rates increased approximately 5% for this group 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.

Gross written premiums increased $89 million (11%) in 2022 compared to 2021 due primarily to higher premiums in the financial institutions business related to lender-placed mortgage protection insurance, rate increases and new business opportunities in the fidelity business and new business opportunities in the innovative markets and commercial equipment leasing businesses. Average renewal rates for this group increased approximately 5% in 2022. Reinsurance premiums ceded as a percentage of gross written premiums increased 2 percentage points in 2022 compared to 2021 reflecting the impact of reinstatement premiums related to Hurricane Ian and higher cessions in the innovative markets business.

Other specialty The amounts shown as reinsurance premiums ceded represent business assumed by AFG’s internal reinsurance program from the operations that make up AFG’s other Specialty property and casualty insurance sub-segments. Reinsurance premiums assumed increased $10 million (4%) in 2023 compared to 2022, and $34 million (16%) in 2022 compared to 2021 reflecting an increase in premiums retained, primarily from businesses in the Specialty casualty sub-segment.

Current accident year losses and LAE, excluding COVID-19 related and catastrophe losses

The current accident year loss and LAE ratio, excluding COVID-19 related and catastrophe losses for AFG’s Specialty property and casualty insurance operations was 62.4% in 2023, 62.8% in 2022 and 61.6% in 2021.

Property and transportation The 1.1 percentage points decrease in the loss and LAE ratio for the current year, excluding COVID-19 related and 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.

The 4.4 percentage points increase in the loss and LAE ratio for the current year, excluding COVID-19 related and catastrophe losses in 2022 compared to 2021 is due primarily to lower profitability in the crop insurance business compared to the very strong results recorded in 2021. Excluding crop, the loss and LAE ratio for the current year, excluding catastrophe losses was comparable in 2022 and 2021.

Specialty casualty The 1.5 percentage points increase in the loss and LAE ratio for the current year, excluding COVID-19 related and 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.

The 1.7 percentage points decrease in the loss and LAE ratio for the current year, excluding COVID-19 related and catastrophe losses in 2022 compared to 2021 reflects favorable trends in workers’ compensation and the impact of higher rates in the executive liability, excess and surplus and excess liability businesses.

Specialty financial The 0.2 percentage points decrease in the loss and LAE ratio for the current year, excluding COVID-19 related and 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.

The loss and LAE ratio for the current year, excluding COVID-19 related and catastrophe losses in 2022 is unchanged compared to the 2021 period.

Net prior year reserve development

AFG’s Specialty property and casualty insurance operations recorded net favorable reserve development related to prior accident years of $226 million in 2023 compared to $289 million in 2022 and $283 million in 2021, a decrease of $63 million (22%) and an increase of $6 million (2%), respectively.

Property and transportation 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.
