Was just wondering if I should bother with Panjer at all. Completely forgot it was even something I read about until I saw one of the 2013 questions on it

He calculates it out to $1813, and the Bahnemann math does get that answer even if you don't round anything. It doesn't make any sense to me why I can't just reduce all the excess claims by $5000. I actually did a similar subtraction thing for all of them, without ever using 1- F(x), and got answers very close to his but not quite the same. It seems like a perfectly legitimate way to go about solving the problem.

Maybe I'm just tired...
I thought the same thing, so I'd be curious as well as to why our method wouldn't be reasonable

In other news, TIA #3 has proven definitively that I do not actually understand any of the material on this exam. Any oddly phrased questions I will have to partial credit my way through by making assumptions that make them similar to ways I've seen the information presented in the past.

Also the prospect of being given distributions in Bahnemann instead of being told what things like E[X^2;a] equal is horrifying.

Wait, you want me to determine E[x^2;a] via integration? F***. I haven't done that since P. Next problem.

Also the phrase "Expected aggregate losses limited to $500" is ambiguous. Is that an occurrence limit or an aggregate limit?

Spoiler:
It's an occurrence limit...

Yeah, like, I can calculate Table L charges all day- but ask me to tell you *why* it accounts for things differently than ICRLL or Limited Table M? Yeahhh maybe, but probably just a big nope from me

Anyone have a memory trick for knowing the difference between the PAFs from rules 13B and 13C (for ISO Experience rating). I constantly get them mixed up and anytime I try to understand what they're actually doing I feel like I'm just reading the same words for both of them
