When the going concern concept is no longer applicable, the fixed assets are recorded at their

The going concern concept assumes that a business will continue operating for the foreseeable future and will not be forced to sell off its assets or cease trading in the near term. This assumption is what allows fixed assets to be recorded at cost less accumulated depreciation, on the basis that they will be used over their full working life rather than sold immediately.

When the going concern assumption no longer holds, for example because the business is being wound up or liquidated, this basis of valuation is no longer appropriate. The relevant question is no longer how much value the asset will contribute through years of use, but how much money the asset could actually be sold for now. This amount is the realizable value, the price the asset would fetch if sold in its current condition, often less than its book value because a forced or urgent sale rarely achieves full market price.

Net book value (cost less accumulated depreciation) and gross value (original cost) both assume the business will keep using the asset, which is no longer valid once going concern fails. A revalued amount reflects a fresh estimate of an asset's worth to a continuing business, which again depends on the business carrying on, not winding up.

Examination tip: once going concern no longer applies, valuation shifts from "value in continued use" to "value on immediate sale," which is the realizable value.
