Net realized gains$9.6M-36% YoY

$10.3M realized gains on equity securities primarily from rebalancing, offset by $0.4M losses on fixed income.

Net unrealized losses on equity securities$(39.4)MImproved from $(42.3)M YoY

Market declines resulted in unrealized losses; improvement vs. prior year reflects equity market performance.

Largest Expense Items

Losses and settlement expenses$193.2M+9% YoY

$35M favorable prior-year reserve development; offset by $16M catastrophe losses vs. $12M in 2025.

Policy acquisition costs$132.1M+7% YoY

Increased due to continued investments in people and technology across segments.

Insurance operating expenses$28.3M+5% YoY

New $300M debt issuance at 5.375% on March 3, 2026 increased debt to $347M (16% of capital); debt service expense rose 76% YoY to $2.4M.
