Single Time and Form of Payment Question

[Guest Lane]

I have looked at other posts on this, but welcome feedback on this simple scenario:

1. Plan provides for deferral contributions and matching contributions. Distribution of these amounts can be lump sum or installments, at the participant's election.

2. Plan also provides for employer non-elective contributions. Employer would like to provide that these amounts are only paid in lump sum.

The matching and non-elective contributions are aggregated under the plan aggregation rules.

Can the plan provide the desired "lump sum only" treatment for the non-elective contributions, even though installments are an option for the matching contributions?
