There was a movie many years ago called The Butterfly Effect. It talked about the consequences that can flow from something seemingly small. I look at that in this context. We have the existence of black swan events. We have the possibility that many of these factors together could coalesce and do this, or any one of them.
How many scenarios in the existing report is the chief actuary able to envision? It's not just about any one of these as individual.... You also have to look at the overlap between a lot of these things.
