1. It seems to me that if you are testing a DB/DC combo, which you indicated that you are, and the DC plan preceded 2004, then your measurement period does not necessarily have to be the current plan year. I think you could use years benefiting under either plan.
2. If you are trying to average 1 year of accrual over three years of compensation, even if the person only worked 2.5 years, then it is not clear to me whether or not that is permitted. I think not.
1.401(a)(4)-3(e)(2)(i) says that the employees compensation history must be "no shorter than the averaging period". I think that paragraph can be interpreted to prohibit what you want to do. But it is not entirely clear. Absent anything else, I would not do that if you need it to pass.
3. You asked a couple of questions:
QUOTE
Is not my testing service limited to 1 for 2004 whether the measurement period is cur yr or current and all prior yrs?
Not necessarily. See 1 above. Also, clearly no if the DB granted past service.
QUOTE
Does the accrual based on participation limit the use of a historical ave comp for determining the EBAR?
No.
QUOTE
What I am trying to do is to take the current year accrual based on current year comp (participation comp) and divide that by the 3 yr ave sal described in the prior post. In that case I suppose the measurement period would be the current yr plus all prior years
No, I do not agree. The comp averaging period does not define the measurement period. The measurement period may affect your options regarding the comp averaging period, however.
