This is a very basic question as I'm not familiar with the terms or context here.
In the Loss Ratio method (Table 1 pg 222) showing the calculation for a single policy - can someone explain the columns?
Specifically

column (3) ELR - didn't Seiwert say the loss ratio used is that which was used to price each policy - i.e. the excess LR for the excess layer priced, if so what is the Excess Ratio used for?

If it's the full coverage LR that he mentions that we can get from industry experience, thus apply the excess ratio to get the portion ABOVE the deductible why is it named "Deductible" Loss Charge?

Lastly, what is the Aggregate Loss Limit Charge? We apply it to the full coverage (ground up) losses - the excess losses (?) col(6) - i.e. this is losses BELOW the deductible.
Shouldn't it be applied to losses above the deductible (i.e. subject to the agg. loss limit)?

Now, assuming that it is applied to the excess losses, does this mean it (e.g. 2%) is saying that we expect 2% of excess losses to be capped by the agg. loss limit. So does this mean that the amount in column (8) is an amount that we want to EXCLUDE from losses (then why is it called a "charge").

Sorry for so many questions, mostly it seems there's a prerequisite knowledge base necessary in order to understand what's going on in this paper.

I don't have the article in front of me, so I can't answer all the questions. However, I think you are confused about the aggregate in this case. The aggregate Siewert is referring to is an aggregate payed by the insured. In other words, they will pay a $5,000 deductible per claim, with a $100,000 aggregate. This means they will pay up to $5000 for each claim they have until they have payed $100,000 and then the deductible no longer applies for the remainder of the policy term. It is not an aggregate payed by the insurance company.

Two threads on this paper already. Both define Aggregate Loss Charge:
