11.1 Employee benefits liabilities

The Group is obliged to pay specified benefits following the period of employment (retirement benefits due to one-off retirement-disability rights, post-mortem benefits and the coal equivalent) and other long-term benefits (jubilee bonuses), in accordance with the Collective Labour Agreement. The amount of the liabilities due to both of these benefits is estimated at the end of the reporting period by an independent actuary using the projected unit credit method.

The present value of liabilities from these benefits is determined by discounting estimated future cash outflow using the  yield on treasury bonds expressed in the currency of the future benefits payments, with maturities similar to the date of settlement for liabilities. Actuarial gains and losses from the measurement of specified benefits following the period of employment are recognised in other comprehensive income in the period in which they arose. Actuarial gains/losses from
the measurement of other benefits (benefits due to jubilee bonuses) are recognised in profit or loss.

The carrying amount of the liability due to future employee benefits is equal to the present value of the liabilities due to defined benefits. The amount of the liability depends on many factors, which are used as assumptions in the actuarial method. Any changes to the assumptions may impact the carrying amount of the liability. Discount rates are one of the basic parameters for measuring the liability. At the end of the reporting period, based on the opinion of an independent actuary, an appropriate discount rate for the Group’s companies is used for setting the present value of estimated future cash outflow due to these benefits. In setting the discount rate for the reporting period, the actuary applies yields of State Treasury bonds available at the balance sheet date, with maturities approximate to the average maturities of measured liabilities.

Other macroeconomic assumptions used to measure liabilities due to future employee benefits, such as the inflation rate or the minimum salary, are based on current market conditions.

Pursuant to IAS 19 paragraph 78, actuarial assumptions adopted for measurement of employee benefits in the Group are consistent because they reflect the economic relationships between factors such as inflation, a salary growth rate, a discount rate and a coal price growth rate. The additional analysis of assumptions prepared by the Parent Entity determined that the balance of provisions achieved using the adopted assumptions as to the salary growth and coal price growth could be achieved using the alternative paths of price growth of 6.0% and coal price growth of 6.25%. Taking into account the adopted finance discount rate of 6.75% it should be noted that the assumptions adopted for the measurement are consistent, pursuant to IAS 19 paragraph 78.

The assumptions used for measurement as at 31 December 2022 are presented in Note 11.2.

The sensitivity of future employee benefits liabilities to changes in the assumptions was set based on the amounts of the Parent Entity’s liabilities (the Parent Entity’s liabilities represent 91% of the Group’s liabilities in the current year and 88% in the previous year). In the remaining Group companies, due to the immaterial amounts of liabilities in this regard, the impact of changes of the basic parameters adopted for the calculation of provisions on future employee benefits liabilities in the consolidated financial statements would be immaterial.
