How to Record Actual Decommissioning Costs and Settle the Asset Retirement Obligation
Recording the costs incurred to plug a well and restore the site at end of life, settling the ARO liability.
| Account Name | Type | Debit ($) | Credit ($) |
|---|---|---|---|
| Asset Retirement Obligation (Settled) | Liability (-) | 10,000,000.00 | - |
| Cash / Accounts Payable (Contractors) | Asset/Liability (-) | - | 9,500,000.00 |
| ARO Settlement Gain (Under-Spend) | Revenue (+) | - | 500,000.00 |
💡 Accountant's Note
When actual decommissioning occurs, the ARO liability is settled. If actual cost differs from the provision, the difference is a gain or loss. Effective ARO estimation can result in significant gains or losses.
Practitioner & Systems Framework
💻 ERP Architecture
As decommissioning costs are incurred, debit the ARO liability (drawing it down) and credit cash/payables. At completion, any balance remaining in the ARO liability is a settlement gain (over-provision); any shortfall requires additional expense recognition. For major offshore decommissioning projects lasting multiple years, track cumulative spending against the provision monthly and update the provision as better cost information becomes available during the decommissioning execution phase.
⚠️ Audit Flags
Settlement gains from decommissioning under-spend are scrutinized — large gains may suggest the original provision was overstated (which would have understated income in prior periods). Auditors will test the decommissioning contractor invoices, the scope of work completed (confirmed through regulatory sign-off that the site meets restoration standards), and the final cost vs. provision reconciliation. Environmental regulators' sign-off on site restoration is required to confirm the ARO is fully extinguished.
📄 Required Documentation
Decommissioning contractor invoices and scope of work, progress billing schedule, regulatory authority site restoration certificate, final cost vs. ARO provision reconciliation, settlement gain or loss calculation, decommissioning security release documentation, and post-decommissioning environmental monitoring requirements.
