 early claims reports to determine an appropriate reserve for the catastrophe. These reserves are reviewed frequently to reflect actual reported losses and changes to our estimates are made to reflect the new information.

Our Reserve Committee consists of our Chief Actuary and other select members of senior management. The Reserve Committee meets quarterly to review the actuarial recommendations made by the Chief Actuary. In establishing the actuarial recommendation for the reserves for losses and loss adjustment expenses, our actuary estimates an initial expected ultimate loss ratio for each line of business by accident year. Input from our underwriting and claims departments, including premium pricing assumptions and historical experience, is considered by our actuary in estimating the initial expected loss ratios. During each quarter, the Reserve Committee

reviews the emergence of actual losses relative to expectations by line of business to assess whether the assumptions used in the reserving process continue to form a reasonable basis for the projection of liabilities for those product lines. Our reserving methodology uses a loss reserving model that calculates a point estimate for our ultimate losses. Although we believe that our assumptions and methodology are reasonable, our ultimate payments may vary, potentially materially, from the estimates we have made.

In addition, we retain an independent actuary annually to review our estimate of reserves. The independent actuary is not involved in the establishment and recording of our loss reserve. The actuarial consulting firm prepares its own estimate of unpaid loss and loss adjustment expenses, and we compare its estimate to the reserves for losses and loss adjustment expenses reviewed and approved by the Reserve Committee to gain additional comfort on the adequacy of those reserves.

While we believe that loss reserves at December 31, 2024 are adequate, new information, events, or circumstances may result in ultimate losses that are materially greater or less than our estimates. As previously noted, there are many factors that may cause reserves to increase or decrease, particularly those related to catastrophe losses and long-tailed lines of business.

Key assumptions

Expected loss ratios are a key assumption in estimates of ultimate losses for business at an early stage of development. A higher expected loss ratio results in a higher ultimate loss estimate, and vice versa. Estimated loss development patterns are another significant assumption in estimating loss reserves. Accelerating a loss development pattern results in lower ultimate losses, as the estimated proportion of losses already incurred would be higher. We utilize industry benchmarks and peer group data to supplement our own data when estimating loss development patterns.

Each of the impacts described below is estimated individually, without consideration for any correlation among key indicators or among lines of business. Therefore
