31 December 2020 | ​ | Interest Rate | ​ | Inflation Rate | ​
Sensitivity Level |  | 1% increase |  | 1% decrease |  | 1% increase |  | 1% decrease | ​
Change in assumption |  | (14.1) | % | 17.3 | % | 17.6 | % | (14.6) | %
Impact on provision for employee termination benefits |  | (42,566) |  | 52,122 |  | 53,117 |  | (43,953) | ​
​ The above sensitivity analyses are based on a change in an assumption while holding all other assumptions constant. In practice, this is unlikely to occur, and changes in some of the assumptions may be correlated. 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 incurred TL 20,004, TL 14,677 and TL 12,785 in relation to defined contribution retirement plan for the years ended 31 December 2021, 2020 and 2019, 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 2021, the Group has not recognized any expenses regarding this plan (31 December 2020: TL 12,085).
