Asset Revaluation Reserve

Q:
What is asset revaluation reserve?

A:
An asset revaluation reserve is an accounting concept and represents a reassessment of the value of a capital asset as at a particular date. The reserve is considered a category of the equity.
An asset is originally recorded in the accounts at its cost and depreciated periodically over its estimated useful life as a measure of the amount of the asset's value consumed in that period. In practice, the actual useful life of an asset can be miscalculated or an event can cause a change to the useful life. Consequently, assets occasionally need to be revalued in order to reflect a more close approximation to their "worth" in the accounts.

When the asset is revalued, the offsetting entry (in a double entry accounting system) would be either made to the profit or loss accounts or to the equity. The accounting for revaluation increments or decrements and other aspects of asset revaluation is addressed in the Accounting Standards.
