Section 57 in The Companies (Accounting Standards) Rules, 2006
57. Depreciation of an asset begins when it is available for use, i.e., when it is in the location and condition necessary for it to be capable of operating in the manner intended by management. Depreciation of an asset ceases at the earlier of the date that the asset is retired from active use and is held for disposal and the date that the asset is derecognised. Therefore, depreciation does not cease when the asset becomes idle or is retired from active use (but not held for disposal) unless the asset is fully depreciated. However, under usage methods of depreciation, the depreciation charge can be zero while there is no production.
