Not sure but I think the target remained at 2.5Bn AED. Then its profit, divide by 5 (20%), shared out. Now a greater profit means a lower payout. When the target was 1.75Bn AED = 10 weeks, last year 2.5Bn AED = 4 weeks. Record first half profits this year and the profitable half of the year to go AND a stationary taget .INCREASED PROFIT = LOWER PAYOUT = 2 WEEKS, from the proven formula. Its calculated under the FTLs principle, except there are many more variations applied here.
Hope that helped.
