Combo plan testing with otherewise excludable employees

Looking at a DB/DC combo and checking on otherwise excludable (OEX) testing

Do I need to have an HCE in the OEX group for the PS portion? This is for 401a4 only as 410b passes easily without separating the groups (this is NESH plan with 3% mandatory allocation)

It makes a difference in the gateway as I have 5 NHCEs that are OEX.

Thanks

No. You’re not doing component testing. The OEX group is whomever fits that eligibility stratum. 

Perfect, thank you for reminding me about component HCE requirement.

All the best
