Capitalized asset retirement cost is included in long-lived asset impairment testing on the same basis as for any other entity.","key_points":["Nuclear plant decommissioning costs are incurred costs imposed by regulation or statute (similar to the obligation to restore land after strip mining), so paragraph 980-405-25-1(b) does not address those costs (410-980-25-1).","Rate-regulated entities may recover retirement costs in customer rates on a timing pattern that differs from period cost recognition under Subtopic 410-20, and a timing difference can also arise when retirement costs are included in amounts charged to customers but no liability is recognized (410-980-25-2).","If the requirements of Topic 980 are met, the regulated entity recognizes a regulatory asset or regulatory liability for the difference between financial reporting recognition of ARO period costs and rate-making recognition (410-980-25-2).","Some retirement costs recovered in rates arise from AROs within the scope of Subtopic 410-20 and others do not; only the former follow that Subtopic (410-980-25-2).","The capitalized amount of an asset retirement cost is included in the impairment assessment of a rate-regulated entity's long-lived assets just as for any other entity (410-980-35-1).","Subtopic 980-360 applies to the asset retirement cost related to a rate-regulated long-lived asset that has been closed or abandoned (410-980-35-1).","The Subtopic follows the same scope and scope exceptions as Section 980-10-15 (410-980-15-1)."],"categories":["Recognition","Impairment","Industry-specific","Subsequent measurement"],"audience_level":"intermediate","student_note":"This is the bridge between the ARO model and rate regulation: utilities still record AROs under 410-20 for financial reporting, and the rate-recovery mismatch is resolved through a regulatory asset or liability rather than by deferring the ARO itself.
