New Comparability Design and SPD

[Guest LKHartnett]

In a plan with a cross tested design, must the SPD provide a breakout of the employee groupings?

For instance, in the section of the SPD which describes the Non-Elective Contribution, would it be necessary to say that, "Your contribution is based on the relationship of your compensation to the total compensation for all participants in your employee group. Employees are grouped as follows:

Group A doctors

Group B physician assistants

Group C nurses

Group D administrative & clerical

Is that too much information, or is it required?
