The Partnership is self-insured for general and product, workers’ compensation and automobile liabilities up to predetermined amounts above which third party insurance applies. As of September 30, 2023 and September 24, 2022, the Partnership had accrued liabilities of $61,182 and $64,065, respectively, representing the total estimated losses for known and anticipated or unasserted general and product, workers’ compensation and automobile claims. For the portion of the estimated liability that exceeds insurance deductibles, the Partnership records an asset within other assets (or prepaid expenses and other current assets, as applicable) related to the amount of the liability expected to be covered by insurance which amounted to $15,448 and $15,710 as of September 30, 2023 and September 24, 2022, respectively.

The Partnership has been, and will continue to be, a defendant in various legal proceedings and litigation as a result of these operating hazards and risks, and as a result of other aspects of its business. In this regard, the Partnership’s natural gas and electricity (“AES”) business was sued in a putative class action suit in the Northern District of New York. The complaint alleged a number of claims under various consumer statutes and common law in New York and Pennsylvania regarding pricing offered to electricity customers in those states. The case was dismissed in part by the district court, but causes of action based on the New York consumer statute and breach of contract were allowed to proceed.

The plaintiff has filed an appeal to the Second Circuit Court of Appeals. The matter has been fully briefed, argued, and a decision is pending. While the Partnership believes that the appeal is without merit, the Partnership is unable to predict at this time the ultimate outcome of the New York action. Accordingly, it was determined that no reserve for a loss contingency is required. If the plaintiff prevails on appeal, the matter will return to the trial court for further proceedings. If the Partnership is ultimately unable to successfully defend its AES business in this class action lawsuit, a decision rendered against AES could have an adverse impact on AES’s business and operations.
