The reference to AVCs suggests a final salary scheme.
To ensure a like for like comparison ideally it would be useful to see the CEs and scheme booklets.
It is simplistic to assume all final salary schemes are equal (and in fact yours is now a career average scheme)but it would appear that neither is money purchase so there shouldn''t be a huge disparity.
My only other thought is that my s2bx has recently completed her degree course and now the kids are off to uni she will seek to extend her career and seek promotions. This was ''our'' plan previously. That will give increased earning and pension potential.... May be usefull arguements if push comes to shove but my pref would be for it to be done without pension inclusion.
Both pensions may be defined benefit (either final salary, career average earnings or combo) that does not mean that the CETVs are directly comparable. The CETV is the value that the scheme places on the accrued benefits (the benefits built up based on service to date). Each scheme will have it''s own basis for calculating CETVs so you could have identical benefits under two different schemes but the CETVs would differ.
The only way to compare the two pensions on a consistent basis is for an actuary to value both pensions. It is not possible to tell in advance whether this would be to your advantage or your stbx''s.
You should, at the very least ensure that the CETVs are both calculated at or around the same date.
Hope that helps.
