💡 Accountant's Note

If a new engineering study suggests that capping the landfill will cost more than previously estimated (due to inflation, new EPA rules, or labor costs), the liability must be increased. The offset is an increase to the Asset, which is then depleted prospectively over the remaining life of the landfill.

Practitioner & Systems Framework

💻 ERP Architecture

Requires a 'catch-up' calculation or a modification to the asset record in the FA module to adjust future depletion rates.

⚠️ Audit Flags

Large upward revisions may trigger an 'impairment test' on the landfill asset if the costs to close significantly erode the site's profitability.

📄 Required Documentation

Updated engineering cost-to-close report and a revised PV model.
