All, Don’t mean to add to the confusion, but the formulas we’re being given in Schweser are different that what’s on the CFA text. I’m having a hard time understanding the rationale behind both … I can’t seem to grasp this. Look at problem 33 pg 134 of the FSA book (CFA) This how it is in the CFA text: Econ Pen Exp = Adj change in PBO - Adj change in plan assets, where … Adj delta in PBO = End PBO - Beg PBO + Benefits paid; and Adj delta in plan assets = End plan assets - beg plan assets - employer contributions + benefits paid So in essence, we can look at it this way: Econ Pen Exp = End PBO - Beg PBO - (End plan assets - beg plan assets - employer contributions) … benefits paid would offset each other How is that similar to this? 1. End PBO - Beg PBO + Benefits Paid - Actual Return on Plan Assets 2. End FS - Beg FS - Employer Contributions. 3. Service cost + interest cost + plan amendments - actual return on assets
clama, (End plan assets - beg plan assets - employer contributions) = Actual Return on Plan Assets 
Thanks. I think that’s what I was missing.
