Hi, anyone can help me to understand the following point regarding reserving for outwards RI by using method "reserving using data gross and net of reinsurance", one of the disadvantages are "not adequately reflect changes in the gross book of business"? any chance provide an example ? thank you very much
If the gross book has changed, then the development patterns derived from the historical gross triangle may no longer be appropriate for projecting the gross experience into the future.
