Reserving & close: Triangles, IBNR, and the quarterly cycle

The triangle is squared before you sit down.

Point the study at last quarter and the methods come with it: your factors, your tail, your selected ultimates, carried forward rather than rebuilt. The quarter opens on the newest diagonal and whether it moved.

What that afternoon is made of.

Our own timings, from running this work ourselves. Nobody has audited them and no customer has been asked to stand behind them. Measure them against your own close rather than against ours.

Every base rate, factor, credit and trend number carries the page and cell it came from. So you can defend the number in the room, instead of going away to work out where it came from. An audit agent regrades the whole analysis against the CAS Statements of Principles before anybody on the committee sees it.

Distributions fitted with credibility weighting, the segments broken out, and the memo written the way a memo gets written.

Last quarter, linked as the predecessor

The selections you made last time come across with the study, so actual-versus-expected is on the screen, not on somebody’s list of things to rebuild.
