Hi Am I (I'm sure) reading the solution wrongly? It seems to me 1 out of the 6 methods suggested are redundant: "Extract the whole claim incl history if exceeds threshold" Vs "Once large always large." Sounds the same to me.
Hi Jensen, These two methods are different: "Extract the whole claim including history if exceeds threshold" - this considers the claim amount as at the time of the reserving exercise. If it is above the large loss threshold then the whole claim is removed from the triangles. "Once large always large" - as at the time of the reserving exercise, the claim amount may be lower than the large loss threshold. However, if it had been higher than the threshold at any time in the past then it would still be removed (even though it is no longer classified as a large claim). This question was repeated in April 2012 so have a look at ASET for a fuller discussion of the advantages and disadvantages of each of the six approaches. Coralie
