general query about run off triangles

chapter 15 pg 13 ... "we would normally expect origin years to be more developed as they get older..."

When do we say that a year in a triangle is more (or less) developed? as in.. is it called more developed if more number of claims are settled or reported or is there any other criteria?

Thanks in advance,
Anuj

 

general query about runoff triangles

I guess it depends what kind of triangle you're looking at (e.g. a claims reported triangle, or a claims paid triangle etc). It's just saying that older origin years will usually be more developed, i.e. nearer their ultimate position.

This is really just stating the obvious (although I think it goes on to give some examples of situations where this doesn't apply), so I wouldn't over-think this statement.
