As per AS 10

1)In Cost Model Non Asset is valued at the price spent to acquire the Asset less accumulated Depreciation and any Imperiment loss of an asset.

2) In Revaluation Model Non current Assets are shown at Fair market value price less accumulated Depreciation and any Imperiment loss of an asset .

So as per above method you can identify value of Non current Assets . valuation is done only one's in cost method and with regular intervals in revaluation method .

Could you plse example with case study like A B

There is a difference between revaluation model and cost model.

How can I find out this is cost model I should have to recognise and this is revaluation method I should have to recognise??
