ASC 410-980 explains how rate-regulated entities apply the asset retirement obligation (ARO) model of Subtopic 410-20. Because rate regulation may allow recovery of retirement costs on a timing pattern different from GAAP ARO cost recognition, a regulated entity that meets the requirements of Topic 980 recognizes a regulatory asset or regulatory liability for that timing difference. Capitalized asset retirement cost is included in long-lived asset impairment testing on the same basis as for any other entity.

This Subtopic governs how entities with regulated operations account for the financing cost of construction — the allowance for funds used during construction (AFUDC), which includes both a computed interest component and a designated cost of equity funds. When a regulator requires such capitalization, the rate-making amount (not the amount computed under Subtopic 835-20) is capitalized for financial reporting purposes, but only if subsequent inclusion in allowable costs for rate-making purposes is probable. The credit is reported in the income statement as other income, a reduction of interest expense, or both.
