(F1) NRV vs Fair Value Less Costs to Sell

Hi Currently studying for my CIMA F1 exam next week and trying to condense study notes into digestible revision cards! Please can you clarify if there is a material difference between applying the concepts of (IAS 2) NRV (Net Realisable Value) and (IAS 36) Fair Value Less Costs to Sell. Although the wording of the standards is slightly different, both definitions seem one in the same to me. My revision flash cards basically look like this: Inventories: Lower of cost and NRV Impairment of Asset: When Carrying amount > Recoverable amount Recoverable amount: Greater of NRV and Value In Use (VIU) VIU: Present Value of Future Cash Flows Basically I am assuming NRV = Fair Value Less Costs to Sell. I understand that they refer to inventory valuation and impairment of assets respectively however for the purposes of exam revision can I substitute them for one another or am I heading for trouble? Your help would be much appreciated! PS Could you please also clarify if IAS 36 can be applied to a current asset as the standard states it should be applied to ALL ASSETS except ones which it specifically identifies. An example of IAS 36 on a current asset would be very helpful ? Thanking you in advance
