Section 59 in The Companies (Accounting Standards) Rules, 2006
59. The useful life of an asset is defined in terms of its expected utility to the enterprise. The asset management policy of the enterprise may involve the disposal of assets after a specified time or after consumption of a specified proportion of the future economic benefits embodied in the asset. Therefore, the useful life of an asset may be shorter than its economic life. The estimation of the useful life of the asset is a matter of judgement based on the experience of the enterprise with similar assets.
