§Impairment of Assets
   IAS 36 set out the procedures that an entity should apply to ensure that its assets are carried at no more than their recoverable amount. 
   Recoverable amount :- The higher of its F.V less costs to sell and its value in use. 
   Value-in-use:- The discounted present value of the future cash flows expected to arise from an asset or a cash-generating unit. 
   Cash-generating unit:- The smallest group of assets that can be identified that generates cash flows independently of the cash flows from other assets. 
   Fair value less costs to sell:- The amount obtainable from the sale of an asset or cash generating unit in an arm’s-length transaction between knowledgeable, willing parties, less the costs of disposal. 
   Impairment loss:- The amount by which the carrying amount of an asset or cash-generating unit exceeds its recoverable amount. 
   Under IAS 16 “Property Plant and Equipment” any change in the useful life will be accounted prospectively.
