228 MKH BERHAD | ANNUAL REPORT 2023 30. PROVISIONS (CONT’D) (a) Post-employment benefit obligations (Cont’d) The defined benefit obligation expenses were determined based on actuarial valuations prepared by an independent actuary using the projected unit credit method. Principal assumptions at reporting date are as follows: The Group 2023 2022 Discount rate 7.00% 7.50% Future salary increase 8.00% 8.00% Resignation rate 22% per annum until age of 18 then decrease linearly to 0% at age 57 / 6% per annum until age of 38 then decrease linearly to 0% at age of 57 22% per annum until age of 18 then decrease linearly to 0% at age 57 / 6% per annum until age of 38 then decrease linearly to 0% at age of 57 Sensitivity analysis The sensitivity analysis below has been determined based on reasonably possible changes in the discount rate and future salary increase occurring at the reporting date, while holding all other assumptions constant. The Group Increase/(Decrease) in profit 2023 2022 RM RM Discount rate increase by 1% 1,280,688 1,085,386 Discount rate decrease by 1% (1,466,282) (1,226,605) Future salary increase by 1% (1,437,921) (1,238,479) Future salary decrease by 1% 1,367,484 1,115,909 The sensitivity analysis presented above has been determined using deterministic method and may not be representative of the actual change in the defined benefit obligation as it is unlikely that the change in assumptions would occur in isolation of one another as some of the assumptions may be correlated.
