I have a plan where the participants individually invest... and the plan sponsor lets them invest in about everything under the sun (all legal of course)... They get quarterly statements from all their investment companies.... to comply with ppa, do i have to have a combined statement with the PD and vesting language or can i send a notice explaining that they recieve statements from so and so and the newly required language?

You can send a separate notice, or supplemental statement or whatever you want to call it. The DOL Field Assistance Bulletin (2006-03) said multiple statements were OK.
