IRIS 11
There's this difference going on, and it's bugging me.
In the Annual Statement > 5 Yr Historical Data > Line 74 = Development of INCURRED. That fits with where the numerator comes from: Sched P Part 2 Column 11. We're measuring the change in ULTIMATE.
But then IRIS calls it RESERVE development, and totally focuses on the reserves.
I think IRIS got it wrong.
Suppose over the year, I pay out all my claims and the reserves drop to 0. I would get IRIS ratio 11 = 0%. The focus is on ultimate devlopment, not reserve development.
Comments
IRIS refers to that same location in Schedule P when it says "reserve development."
