2006 #34 and 2002#17

[actuariallady]

For 2006 #34 part c, the solution says 500/(1-26.7%-11.3%)=806.45
why not use 500*(1+11.3%)/(1-26.7%) ?

For 2002#17 part b, the solution just simply rerate the policy with rate after the change, why not use the parallelogram method to calculate the on-level factor and apply it to the earned premium?

THanks a lot !~

Are you sure you provided the correct problem for this?

What is the 11.3% for?

Time yourself on how long it'd take you to calculate the on-level factors vs. calculating 200*132 + 100*112.20. (or 200*120*1.1 + 100*120*1.1*0.85).



Also, see my sig line--it might answer your first question as well.

Agree with VA. The first problem I can't find so maybe you're mixing problems up. The second problem they give you exposures which should be the tip that parallelogram method is not the way to go here. If the gave you earned premium instead of exposures, then your method would be the right - and only - way to go.

Sorry . . . needed to correct this.

Not true if they give either the exposures or the base rate.

You get my point. Besides, I have yet to see an exam problem (pre-2008) that has enough information to let you choose which method you want to use to on-level premium i.e. there is always a very clear, "quick" way to on-level premium.

You should see Future Fellows article on changes in direction on the types of problems Exam writers are being asked to write . . . I'll see if I can find the link.

Bottom line - just know your [stuff].

Thank you guys so much for the quick replies.
For the first question, it is on the TIA chapter 7 page 168, oh, it said ``revised``, that`s why it is not the same as the old exam question.
Basicly, for part a) it is asking the fixed expense ratio F=11.3%
part b) asking for the VPLR=73.3%
then part c), asking for the overall indicated ave premium, the solution used 500/(1-26.7%-11.3%)=806.45
but why not use 500*(1+11.3%)/(1-26.7%) ?
which is consistent with the pure premium formula.
