Definition of Asset Write-offs:
The term write-off describes a reduction in recognized value. In accounting terminology, it refers to recognition of the reduced or zero value of an asset no longer in use. Assets that are natural resources, which are used throughout the course of business, are subject to periodic depletion. When the asset has been depleted to a value of zero or its value has dropped to less than its salvage value, the asset's remaining book value, as calculated by the original historical cost minus the depletion of prior years, is removed from the balance sheet through a write-off.
When natural resources have their value reduced to zero they are written off.
An asset write-off removes an asset's cost off the balance sheet and expenses it on the income statement.
Writing Off Assets with No Value
An asset is written off the balance sheet by recording a journal entry. The write-off journal entry moves the asset's book value to the income statement, where it is reported as an expense or loss and reduces the accounting period's income. The journal entry will credit (decrease) the asset's account balance (equal to its historical cost) and debit (decrease) the balance in the accumulated depletion account. The asset's book value (historical cost minus accumulated depletion) is the amount debited (increased) to an expense or loss account reported on the income statement for the accounting period. The decrease in the asset and accumulated depletion accounts reduces the balance to zero and removes the account from the balance sheet.
Asset Write-offs Vs. Impairment
Asset write-offs should not be confused with impairment. A write-off journal entry removes an asset not in use and its related contra account (accumulated depletion) from the balance sheet. If the asset has suffered a permanent reduction in value, the amount of the asset impairment is expensed on the income statement as a reduction to the accounting period's income. The asset's balance is reduced by the impairment amount to reflect the asset's new economic value and the account remains on the balance sheet.
