DOL - Blackout periods

[fidu]

In today's Federal register the DOL issued a final rule relating to ERISA plan black out periods.

Anyone able to provide a synopsis/overview on how this effects trustees and custodians of ERISA governed employee benefit plans??

Thanks

[E as in ERISA]

The trustees have to decide whether the plan administrator's compliance with the specific disclosure requirements will also satisfy their fiduciary responsibility to participants in regard to blackouts.

and if for some reason the plan administrators violate these rules and blackout without adequate notice, or for a prohibited timeperiod, whats a trustee to do?

any specific examples would be helpful
