The principal or the most advantageous market must be accessible 
to the Group.All assets and liabilities for which fair value is measured or disclosed 
in the consolidated financial statements are categorised within the 
fair value hierarchy, described as follows, based on the lowest level 
input that is significant to the fair value measurement as a whole:
o Level 1 - Quoted (unadjusted) market prices in active markets 
for identical assets or liabilities.Fair value for measurement and/ or disclosure purposes in these 
consolidated financial statements is determined on such a basis, 
except for share-based payment transactions that are within the 
scope of IFRS 2; leasing transactions that are within the scope of 
IFRS 16 and measurements that have some similarities to fair value, 
but are not fair value, such as net realisable value in IAS 2 or value in 
use in IAS 36.
