The IFRS International Financial Reporting Standards requires companies to review and make entries to impaired assets. this becomes necessary if the carrying amount of the asset is higher than the recoverable amount.
I am therefore suggesting a non-current asset impairment expense account and accumulated impairment account just like that of depreciation. this will help users of manager present very professional financial statement.
when the asset regains it lost value the accumulated impairment account is debited and the non current asset impairment expense account is credited to reverse the entry, if the assets recovery value due to some event is higher that the initial amount written off, the excess is entered as revaluation (increase) to the asset itself.
please read below for more info. it just like depreciation but different context.
All of them (depreciation and non current asset impairement accounts) must net off fixed asset.
