Reflects the Company’s share of Loss and Loss Adjustment Expense related to non-proportional assumed reinsurance business. This amount reflects gross and net reserves related to this treaty and the ultimate incurred amount reflects IBNR only. The Company does not have direct access to individual claim information underlying the assumed reinsurance agreements. The Company does not use claim frequency information in the determination of loss reserves or for other internal purposes. Based on these considerations, the Company does not believe providing claims frequency information is practicable as it relates to this line of business.

(2) Negative payout percentages are due to timing of reinsurance payments, allocations of reinsurance between different lines of business based on actual results, and allocation of reinsurance to different periods for reinsurance treaties in effect for multiple periods. These are primarily associated with larger recoveries from catastrophe events in earlier years of operation.
