What factors are considered when estimating the provision for environmental liabilities for Petro Stopping Center?

According to Petro Stopping Center's 2025 Franchise Disclosure Document, the estimation of the provision for environmental liabilities is based on several key factors. These include current legal and constructive requirements, the available technology for remediation, prevailing price levels, and the expected plans for environmental remediation. These provisions are recognized when a clean-up is probable and the associated costs can be reliably estimated. The amount recognized represents the best estimate of the expenditure required to settle the obligation, utilizing existing technology at future prices and discounted using a nominal discount rate.

However, the FDD also notes that actual costs and cash outflows can differ from these estimates. This is due to potential changes in laws and regulations, shifts in public expectations, price fluctuations, the discovery and analysis of site conditions, and advancements in clean-up technology. The timing and amount of future expenditures related to decommissioning and environmental liabilities are reviewed annually, while the interest rate used for discounting cash flows is reviewed quarterly.

For a prospective Petro Stopping Center franchisee, this means that environmental liabilities are a significant consideration, and the estimates provided are subject to change based on various external factors. It is important to understand that these costs can vary significantly due to regulatory and technological changes, and franchisees should stay informed about these potential shifts to accurately assess their financial obligations. The weighted average period over which decommissioning and environmental costs are generally expected to be incurred is estimated to be approximately 20 years and 7 years respectively. Costs at future prices are typically determined by applying an inflation rate of 1.5% to decommissioning costs and 2% for all other provisions.
