INDEPENDENT AUDITOR’S REPORT 92
those with respect to independence.
We have obtained from the Board of Directors and
the officials of the Company the explanations
and information necessary for the performance
of our audit and we believe that the audit
evidence we have obtained is sufficient and
appropriate to provide a basis for our opinion.
KEY AUDIT MATTERS
Key audit matters are those matters that, in our
professional judgment, were of most significance
in our audit of the Consolidated Financial
Statements of the current reporting period.
These matters were addressed in the context
of our audit of the Consolidated Financial
Statements as a whole and in forming our
opinion thereon, and consequently we do not
provide a separate opinion on these matters.
Significant impact of metal price fluctuations
on the valuation of inventory, operating
profit, and group hedging results
Description of the key audit matter
The market prices of metals (mainly lead
and antimony) may be subject to significant
fluctuations due to supply and demand changes
relating to these metals on the markets. This has a
significant impact on the Group’s valuation of the
inventory, the operating result, and of the hedging
results, and is therefore a key audit matter.
Inventory:
The inventory is valued according to the FIFO
method, which means that the valuation
closely matches the evolution of market prices.
Consequently, significant price evolutions have
a direct impact on the valuation of the inventory
at the end of the closing period. As per
31 December 2023, the inventory consists of
the following components: (i) raw materials
(K€ 14 911), (ii) work in progress (K€ 16 838),
and (iii) finished products (K€ 21 052).
As a result of frequent price changes in the market,
the Group performs a monthly so-called ‘-“lower
of cost or market” - or net recoverability analysis.
The resulting “lower of cost or market” -provision is
calculated on the raw materials of metals, the by-
products and the finished goods. In calculating this
provision, the Group compares the valuation of the
aforementioned inventory items against independent
market benchmarks (such as for example, the
“London Metal Exchange” or “LME” for lead prices)
or the Group uses its own valuation method that is
close to the market price when the market price is not
publicly available (such as for antimony, for example).
Operational and hedging result:
Since there is a time delay between the moment
of a purchase and of a sale, there is a risk that the
operating margin will be subject to the impact
of price fluctuations for metals in the period
between the purchase of the metal as a raw
material and the sale of the finished products.
In order to reduce that price risk, the Group
uses derivatives whereby a distinction must
be made between the metals for which a liquid
market exists (e.g. lead) and those for which
there is no such market (e.g. antimony).
Hedging metals for which there is no liquid market is
mainly done by means of natural hedging of physical
positions, trying to align the buying and selling
positions as closely as possible in order to minimize
price risk. On the other hand, derivatives are used for
metals for which there is a liquid market in order to
limit the price risk on open inventory positions and
future sales and purchase transactions. Due to the
fact that the Group does not apply hedge accounting,
the impact of the derivatives used, is recognized
in the income statement, in accordance with the
principles set out in IFRS 9 “Financial Instruments”.
Summary of the procedures performed
• Evaluation of the design of internal
controls with regard to the valuation of
inventory (and the related derivatives);
• Substantive audit procedures through sampling,
on the valuation of raw materials inventory
of metals and of the valuation of these raw
materials included in the manufacturing price
of work in progress and of finished goods;
• Substantive audit procedures of the market value
determination and the analysis by management of
determining the lower of cost or market provision,
by reconciliation with independent market
data for lead prices and alternative evidence
