text: (d) Fair value measurements 
  The carrying values of financial assets and liabilities of the Group approximate their fair values. Fair values of financial assets and liabilities have been deter- 
  mined for measurement and / or disclosure purposes. 
  
  Fair value hierarchy 
  
  The Group classifies assets and liabilities carried at fair value using a fair value hierarchy that reflects the significance of the inputs used in determining that 
  value. The table following analyses financial instruments carried at fair value, by the valuation method. The different levels in the hierarchy have been defined 
  as follows: 
  
  〉〉  Level 1: quoted prices (unadjusted) in active markets for identical assets or liabilities; 
  
  〉〉  Level 2: 
   inputs other than quoted prices included within Level 1 that are observable for the asset or liability, either directly (as prices) or indirectly 
  (derived from prices); and 
  
  〉〉  Level 3:  inputs for the asset or liability that are not based on observable market data (unobservable inputs).
