#### Reserves for Losses and Loss Adjustment Expenses
Provision is made at the end of each year for the estimated ultimate cost of claims incurred but not settled at the balance sheet date, including the cost of IBNR claims and development of existing reported claims. The estimated cost of claims includes expenses to be incurred in settling claims and a deduction for the expected value of salvage and other recoveries. Estimated amounts recoverable from reinsurers on unpaid losses and loss adjustment expenses are calculated to arrive at a net claims reserve.

Reserves by segment. As at December 31, 2024, we had total net loss and loss adjustment expense reserves of $3,950.6 million (December 31, 2023 — $3,232.8 million). This amount represented our best estimate of the ultimate liability for payment of losses and loss adjustment expenses. Of the total gross reserves for unpaid losses of $8,122.6 million at December 31, 2024, a total of $5,247.7 million, or 64.6%, represented IBNR claims (December 31, 2023 — $4,695.1 million and 60.1%, respectively). The following tables analyze gross and net loss and loss adjustment expense reserves by business segment as at December 31, 2024 and 2023, respectively:
