Fixed Expense Provision

[Nut]

I noticed one of the TIA solutions used

"Projected Fixed Expense per exposure (with trend)" / "Projected Trended Premium at Current Rate Level."

While I think this removes the trend and rate bias, I "think" we can just take

Fixed Expense Prov = "Fixed Expenses / Premium" -- at least from what I read from Werner page 135. Is this correct?

I'm confused because I have seen solutions go both ways. In the appendix, pg A-21 of Werner, they just take Fix Expense/Premium. Same with TIA Quiz 6#1 (although there was enough info to do it the other way using trending and on-level premiums). And, in the TIA Quiz 10 Q1, they project the Fixed expense (as would in the Exposure based method) and then divide it by the Projected on-level trended premium.

Many Thanks for the last second clarification!

the first thing you quoted is the policy/exposure based projection method, converted into a % of premium (this is in W&M as well, maybe 2-3 pages after opage 135). The second one, and what was used in appendix A, is the premium based projection method.

Thanks, but Werner says Werner says on page 135 "However, some companies trend the fixed expense ratio, which implies that average fixed expenses are changing at a different rate than average premium. For the purpose of this text, the fixed expense provision calculated using that methodology is not trended."

Hence, I probably won't trend fixed expenses or used on-level trended premium to calc the Fixed Expense provision, unless it is specifically requested to do that.
