Subsequent Measurement
Subsequent to initial recognition IAS-16 permits an entity to adopt either the cost model or the revaluation model as its accounting policy
Cost Model requires that, after initial recognition PPE should be carried at cost less accumulated depreciation and accumulated Impairment losses.
Revaluation model requires that, subsequent to initial recognition PPE whose fair value can be reliably measured should be carried at a revalued amount, being fair value and the date of revaluation less subsequent accumulated deprecation and any subsequent accumulated impairment loss.
IAS-16 requires that if a single item of PPE is revalued then the entire class of PPE has to be revalued although policy need not to be applied to all classes.
Example:- Entity A, has number of industrial building and official building in several capital cities. Management wants to apply revaluation model on office building and cost model or industrial building.
In the IAS-16, Management can apply different model to different set of buildings because there function, nature and general location all are different.
Separate disclosure of the two classes must be given.
