2010 Form 5500-EZ instructions
The form and instructions are very similar to the ones from prior years. One subtle difference is that there is an explicit instruction that information for both the DB and DC components of an “eligible combined plan” [i.e., a DB(k) plan under IRC 414(x)] should be reported on the same filing.
