Underwriting Ratios

Net income for the three and six month periods increased primarily due to higher net investment income, and for the three month period, a change from net realized losses to net realized gains. The six month period also included lower net realized losses. For both periods, these favorable impacts were partially offset by lower underwriting gains. For further discussion of investment results, see MD&A - Investment Results.

Underwriting Gain

Underwriting gain for the three and six month periods decreased due to less favorable prior accident year development in the current year, higher underwriting expenses, and a higher underlying loss and LAE ratio, partially offset by earned premium growth. For the six month period, these unfavorable impacts were also partially offset by lower CAY catastrophe losses.

Expense ratio for the three and six months ended June 30, 2026 is generally consistent with the prior year, with higher commissions expenses, staffing costs, and technology investments in our business being partially offset by the impact of earned premium growth.
