A valuation is the determination of the economic value of an asset.

LGAM

Regular revaluation is often mandated for infrastructure intensive organisations and is also a requirement with the adoption of the 'revaluation model' option under AASB 116 Property, Plant and Equipment. The revaluation model requires an item of property, plant and equipment whose fair value can be measured reliably, to be carried at a revalued amount, being its fair value at the date of the revaluation less any subsequent accumulated depreciation and subsequent accumulated impairment losses. Revaluations are to be made with sufficient regularity to ensure that the carrying amount does not differ materially from that which would be determined using fair value at the reporting date. When an item of property, plant and equipment is revalued, the entire class of property, plant and equipment to which that asset belongs is to be revalued.
