on page 194 of CFA curriculum there is a blue box that asks who has the less conservative healthcare costs.
CNH shows initial trend at 9% then ultimate trend 5%
Caterpillar shows initial trend 7% and ultimate trend 5%
The answer says Caterpillar appears LESS conservative as its heathcare cost increase of 7% is significantly lower than CNH.
Because it is lower does this not mean that Caterpillar has in fact MORE conservative assumptions?
A bit confused.
