Hi, I am confused by part of the examiner's solution to q9 on the April 2013 paper. When the claims are adjusted for level of cover (limits and excesses) I am unclear as to why to get the adjusted incurred, the original incurred is multiplied by 0.55/ILF. In particular I am confused where the 0.55 came from. Please could someone explain why this is done? Many thanks in advance
ILFs for a layer are the difference between the ILFs at the two limits. So 0.55=1.25-0.70. This is the layer in 2013. Then to change losses from an earlier year, you first calculate the ILF for the layer from that earlier year. Then multiply the losses by the ratio of the two ILFs (2013 layer ILF divided by earlier year ILF). Full details in ASET.
