cross testing and gateway

[Gary]

A company sponsors:

1. 401k with discretionary match plan

2. new profit sharing plan

3. new db plan

required aggregation group

401k passes discrimination on its own

db and ps plans combined and cross tested to pass discrimination.

say it is a TH group and thus the 401k plan provides TH to those only in 401k plan.

However, since 401k plan not being tested with other plans for non discrimination should they provide gateway?

I dont think so.

thanks
