Suspension of Benefits amenment question

I'd appreciate any advice on this:



A plan doesn't have actuarially-increased late retirement benefits nor Suspension Notice language (just continued accrual). The plan is now amending to have: suspended benefits, no AE increase (until 70.5) and does the Notices from now on.



questions:

Assume amendment adopted at participant age 60, retire at 66, Notice given.



1. What benefit must be provided in the future until 70.5?

Max [AE of Accr Ben(60), Accr ben(ret. age)] or

sum of AE of AB(60) + accruals since 60

or?



2. Is the plan free to adopt AE rates, for late retirement increases, less generous than the optional form AE rates? The early retirement rates are not AE type.



thanks.
