Asset retirement cost

At initial recognition, the retirement-obligation debit does not go directly to expense. It becomes part of the related tangible asset's cost. This preserves the connection between obtaining service from the asset and incurring the retirement obligation.

After recognition, two clocks run. The asset retirement cost is allocated through depreciation or depletion as service is consumed. The liability grows through accretion and changes through revisions or settlement. Crediting the liability for depreciation, or debiting the asset for accretion, crosses those clocks and breaks both rollforwards.

The allocation method follows the related asset and supported service pattern. The concept does not assert that every cleanup cost is capitalized or that the initial present value will equal eventual cash paid.

ASC 410-20-25-5 connects the initial recognized liability to the related long-lived asset. The same amount increases the asset's carrying amount. Paragraph 35-2 then requires systematic and rational expense allocation over the asset's useful life. Those paragraphs apply after the obligation qualifies for recognition. They do not turn a management plan into a legal obligation.

The Linden Peak resource and retirement example shows the linked opening amounts and separate later clocks. Test the sequence in the recognition and rollforward practice.
