Certain employees of the Group are entitled to jubilee awards and retirement bonuses. Jubilee awards are paid to employees upon completion of a certain number of years of service whereas retirement bonuses represent one-off payments paid upon retirement in accordance with the Group’s remuneration policies. Both items vary according to the employee’s average remuneration and length of service. Jubilee awards and retirement bonuses are not funded. The cost of providing benefits mentioned above is determined separately for each plan using the projected unit credit actuarial valuation method. This method sees each period of service as giving rise to an additional unit of benefit entitlement and measures each unit separately to build up the final obligation which is then discounted. The calculation is based on demographic assumptions concerning retirement age, staff turnover rates and financial assumptions concerning rates of future salary increases, future interest rates (to determine the discount rate). Actuarial gains and losses on jubilee awards plans are recognised as income or expense when they occur. Actuarial gains and losses on post-employment benefits are recognised immediately in their total amount in the other comprehensive income. The present value of the defined benefit obligations is verified at least annually by an independent actuary. The demographic and attrition profiles are based on historical data. Benefits falling due more than 12 months after the end of the reporting period are discounted using a discount rate determined by reference to market yields on Polish government bonds. The Group recognises termination benefits, which are provided in exchange for the termination of an employee’s employment as a result of either: Termination benefits are provided for when the Group terminates the employment or when the Group has offered to its employees benefits in exchange for voluntary termination of employment. Based on the past practice such offers are considered as constructive obligations and accounted for if it is probable that benefits will be paid out and they might be reliably measured. The basis for calculation of the provision for voluntary employment termination is expected payment dates and the estimated number, remuneration and service period of employees who will accept the voluntary termination. Provision for employment termination benefits is presented in the consolidated statement of financial position in “Provisions”. In addition to post-employment and other long-term employee benefits, the Group also provides to its current and retired employees certain non-monetary benefits, including subsidised telecommunication services. In absence of specific guidance under IFRS, the Group’s policy is to value such employee benefits at their incremental cost net of related revenue generated from the service.
