Basically, the amount has to be distributed in all layers according to the limit in row 3 "max limit of recovery". The limit starts from 15,000,000 and if the amount is less than this amount then no distribution otherwise first layer will get the difference. If the amount is 20,000,000 then first layer will get 20,000,000-15,000,000=5,000,000 and if it is 30,000,000 the first layer will get max 15,000,000 and the same applies to all layers as the balance of amount exceeding the previous layer max limit of recovery will go to next layer upto the respective layer limit and then so on. But sum of all layers, applying max limit, should not exceed 185,000,000.
I hope it is clear.
