Increases in the carrying amounts resulting from the revaluation of land, buildings, plant, machinery, and equipment are recognized, net of tax, in other comprehensive income and accumulated in the revaluation surplus within the statement of changes in equity. If an increase reverses a previously recognized decrease in profit or loss, it is initially recorded in profit or loss. For decreases that offset prior increases in the same asset, the adjustment is first recognized in other comprehensive income, up to the extent of any remaining surplus associated with that asset; any excess decreases are charged to profit or loss.

Upon the sale of revalued assets, the amounts recorded in the revaluation surplus for property, plant, and equipment are transferred to retained earnings.

The company performs revaluations of its fixed assets every five years, or sooner if significant market changes arise.
