Liability reserve estimate	Seaboard accrues liabilities for loss contingencies when it is probable that a loss has been incurred and the amount of the loss can be reasonably estimated. If a range of loss is estimated, and some amount within that range appears to be a better estimate than any other amount within that range, then that amount is accrued. If no amount within the range can be identified as a better estimate than any other amount, Seaboard accrues the minimum amount in the range. For such matters where a loss is believed to be reasonably possible, but not probable, or the loss cannot be reasonably estimated, no accrual has been made.
Management's Assessment and Process	In Seaboard's opinion, it has made appropriate and adequate accruals for loss contingencies where necessary as of December 31, 2023. Substantially all of Seaboard's contingencies are subject to uncertainties and, therefore, determining the likelihood of a loss or the measurement of any loss can be complex. Consequently, Seaboard is unable to estimate the range of reasonably possible loss in excess of the amounts accrued. Seaboard's assessments, which result from a complex series of judgments about future events and uncertainties, are based on estimates and assumptions that have been deemed reasonable by management, including an expected probable loss associated with settling or otherwise resolving such contingencies. These estimates and assumptions may prove to be incomplete or inaccurate, and unanticipated events and circumstances may occur that might change such estimates and assumptions. At the end of each reporting period, Seaboard reviews information with respect to its legal proceedings, claims and other related loss contingencies and updates its accruals, disclosures and estimates of reasonably possible loss or range of loss based on such reviews. Costs for defending claims are expensed as incurred. Any receivable for insurance recoveries is recorded separately from the corresponding liability, and only if recovery is determined to be probable and reasonably estimable.
