Examples of costs excluded from the cost of inventories and recognised as expenses in
the period in which they are incurred are:
(a) abnormal amounts of wasted materials, labour, or other production costs;
(b) storage costs, unless those costs are necessary in the production process prior to a
further production stage;
(c) administrative overheads that do not contribute to bringing inventories to their
present location and condition; and
(d) selling costs.
