Defined contribution plans Obligations for contribution to defined contribution plans are recognized as an expense in the consolidated statement of profit or loss as incurred. The Group is obliged to contribute a certain percentage of personnel wages to pension plans. The Group incurred TL 64,309, TL 66,401 and TL 70,379 in relation to the defined contribution retirement plan for the years ended 31 December 2022, 2021 and 2020 respectively. Share based payments The Group has a share performance based payment plan (cash settled incentive plan) in order to build a common interest with its shareholders, support sustainable success, and ensure loyalty of key employees. The KPIs of the plan are; the total shareholder return in excess of weighted average cost of capital (WACC), and ranking of total shareholder return in comparison with BIST-30 and peer group. Bonus amount is determined according to these evaluations, and it is distributed over a three-year payment plan. As of 31 December 2022 and 2021, the Group has not recognized any expenses regarding this plan.
