S2000 plss assist- IPS confusion!

I came across another question, where they asked pre tax return. This time I stuck to after tax salary - after tax expense… however this time around they did it pre tax, and obviously our final answers too didnt match… whats the catch here…

An example question here - http://www.analystforum.com/forums/cfa-forums/cfa-level-iii-forum/91332684


I’ll look at it Monday afternoon if I have a chance; I’m swamped with last-minute tutoring this week.

ok thanks, great if you could assist with this

From what I’ve seen in the exams is if they ask for after-tax have all your inputs after tax. If they ask for pre-tax, adjust all you inputs to pre-tax. I don’t think I remeber any answers that adjusted the return from after-tax to pre-tax.

they did the reverse here,


also this is an EOC
