Determination of fair values

Available-for-sale instruments are valued using quoted market prices. The values of other investments and forward exchange contracts are determined using directly observable inputs. The carrying amounts of all other financial assets and liabilities approximate their fair values.

Fair value hierarchy

The group uses the following hierarchy for determining and disclosing the fair value inputs of financial instruments:

Level 1: quoted prices in an active market that are unadjusted for identical assets or liabilities;

Level 2: valuation techniques using inputs, which are directly or indirectly observable; and

Level 3: valuations based on data that is not observable (not applicable to the group).

The values of all other instruments recognised, but not subsequently measured at fair value, approximate fair value. The following assets, all measured at level 1, were required to be recorded at fair value as follows:

 
      2017
R’000
    2016
R’000
 
Recurring fair value measurements                
Assets measured at fair value                
Available-for-sale listed investments       229 376     180 084  
Available-for-sale unlisted investments       24 098     44 591  
        253 474     224 675
