with the expiry of the vesting period and the best estimate of the number of equity instruments
that will actually vest.
Service or performance conditions are not taken into account when defining the fair value of the
plan at the assignment date. However, the probability of these conditions being met is taken
into account when defining the best estimate of the number of equity instruments that will vest.
Market conditions are reflected in the fair value at the assignment date. Any other condition
related to the plan that does not involve a service obligation is not considered to be a vesting
condition. Non-vesting conditions are reflected in the fair value of the plan and result in the
immediate recognition of the cost of the plan, unless there are also service or performance
conditions.
No cost is recognised for rights that do not vest in that the performance and/or service
conditions are not met. When the rights include a market condition or a non-vesting condition,
these are treated as if they had vested regardless of whether the market conditions or other non-
vesting conditions to which they are subject are met or not, it being understood that all other
performance and/or service conditions must be met.
If the conditions of the plan are changed, the minimum cost to be recognised is the fair value at
the assignment date in the absence of the change in the plan itself, on the assumption that the
original conditions of the plan are met. Moreover, a cost is recognised for each change that
results in an increase in total fair value of the payment plan, or that is in any case favourable for
employees; this cost is measured with reference to the date of change. When a plan is cancelled,
any remaining element of the plan's fair value is immediately expensed to the income statement.
Use of estimates
Preparation of the separate financial statements in accordance with IFRS requires management
to make estimates and assumptions that affect the carrying values of assets and liabilities and
the disclosures on contingent assets and liabilities at the end of the reporting period. Actual
results might differ from these estimates. Estimates are used to measure tangible and intangible
assets and investments subject to impairment testing, as described earlier, as well as to measure
the ability to recover prepaid tax assets, provisions for bad debts, for inventory obsolescence,
depreciation and amortisation, asset write-downs, employee benefits, taxes, other provisions.
Specifically:
Recoverability of value of tangible and intangible assets and investments
The procedure for determining impairment losses of tangible and intangible assets described in
“Impairment” implies – in estimating the value of use – the use of the Business Plans of investees,
which are based on a series of assumptions relating to future events and actions of the investees’
management bodies, which may not necessarily come about. In estimating market value,
however, assumptions are made on the expected trend in trading between third parties based
on historical trends, which may not actually be repeated.
Provisions for bad debts
Receivables are adjusted by the related bad debt provision to take into account their recoverable
amount. To determine the size of the write-downs, management must make subjective
assessments based on the documentation and information available regarding, among other
things, the customer’s solvency, as well as experience and historical payment trends.
Provisions for inventory obsolescence
Inventories subject to obsolescence and slow turnover are systematically measured and written
down if their recoverable value is less than their carrying value. Write-downs are calculated
