(a)The sale of Charleston Harbor Resort and Marina in August 2026 generated $126 million in pretax net investment income. Since a property and casualty subsidiary and AFG parent each owned half of the property, these earnings are split evenly between the property and casualty segment and holding company results in “Other”.
(b)Significant segment expenses, which are losses and loss adjustment expenses and commissions and other underwriting expenses, are shown in the table below by sub-segment.
(c)Includes interest charges on borrowed money and other holding company expenses. Holding company expenses include special charges of $24 million and $25 million in the third quarter of 2026 and 2025, respectively, to increase environmental liabilities related to AFG’s former railroad and manufacturing operations.
The following table shows the components of underwriting profit, including significant segment expenses, for the Property and casualty insurance segment (in millions):
