Included in other assets in AFG’s Balance Sheet is $192 million at September 30, 2025 and $203 million at December 31, 2024 of amortizable intangible assets related to acquisitions. These amounts are net of accumulated amortization of $69 million and $59 million, respectively. Amortization of intangibles was $5 million in both the third quarter of 2025 and 2024 and $15 million and $14 million in the first nine months of 2025 and 2024, respectively.

This write-off is included in realized gains (losses) on subsidiaries in AFG’s Statement of Earnings.
