Assuming the year required is 2015, then, i have a solution to derive the expected incurred loss in year 2015, different from the two approaches provided in the examiners' report, as below:
1) calculate IBNR as at 31/12/2015 based on BF, similar with that in (iv), i.e. use Ult.-loss-BF of UWY y - (Ult.-loss-CL of UWY y * % dep. y-1)
2) use the IBNR as at 31/12/2014 - the IBNR as at 31/12/2015 (calculated above), to derive the expected incurred loss in year 2015.
does it make sense? but a little bit difference from the results of the two approaches since UWY 2011 and onwards. not so sure why.
thanks!
