Weighted-Average for Control Group

[Guest skim401k]

We have a new 401(k) plan just joined(as of 07/01/2011) the exciting control group that was permissively aggregated in 2010. They are all prior year testing method plans and aggregated % are 3.05(ADP)/2.06(ACP). Since a new plan is using prior year testng method, we use"deemed 3%" for their first plan year. I think that the new plan's "deemed 3%" will NOT effect 2011 weighted-average aggregated % since # of NHCE from prior year is 0(new plan as of 07/01/2011). Do we need to calculate weighted-average aggregated % for 2011 because of the new plan?

I'm confused with your fact pattern; is this a successor plan?

No, it's not a successor plan. A brand new plan just joined the excisting control group.
