When inventories are sold, the carrying amount of those inventories shall be recognised as an expense
in the period in which the related revenue is recognised. The amount of any write-down of inventories
to net realisable value and all losses of inventories shall be recognised as an expense in the period the
write-down or loss occurs. The amount of any reversal of any write-down of inventories, arising from
an increase in net realisable value, shall be recognised as a reduction in the amount of inventories
recognised as an expense in the period in which the reversal occurs.
