- Definition

For the asset that is reclassified back to held and use from held-for-sale, the depreciation expense recognized when the asset is reclassified. This represents the difference between the carrying value at the time the decision to reclassify is made and the carrying amount that the asset would have had if it had never been classified as held for sale (including consideration of depreciation expense).
