18. Asset Retirement Obligation

The Company has recorded asset retirement obligations (AROs) for its legal obligation to complete reclamation of certain mining properties, in the Construction Materials segment, as required by its mining permits with the State of Colorado. The related ARO assets were considered 100% impaired as total carrying value including future costs to maintain and dispose of the asset will exceed the fair value and therefore were previously impaired.

The following table details activity related to the Company’s ARO liabilities (amounts in thousands):

In connection with the third quarter 2019 decision to cease mining activities, management performed a review of remaining assets to determine which, if any, should be classified as assets held for sale (AHS). Based on this review a total of $896,000, previously reported as Machinery and equipment on the Consolidated Balance Sheet, was reclassified as AHS as of December 28, 2019. As of March 28, 2020 a total of $380,000 remains classified as AHS.
