Simple ira Controlled Group

[PFranckowiak]

Company A has a Simple IRA.

Company A owners bought assets only of Company B who had a 401(k) Plan that was not part of the assets purchased/

Can a Simple plan be set up 10/1/10 for Company B with immediate eligiblity (Company A is not immediate)?

How do the limits work between what they contributed in the 401(k) and if they can have a Simple IRA?

Any same desk rule?????

Thanks

Pat
