I provide services, including document drafting, to a pre-ERISA MPPP with a 401k feature that has been grandfathered passed the prohibition of a 401k feature being in a MPPP. The employer is a local governmental entity. So this plan is grandfathered in the additional aspect that a governmental employer has a plan with a 401k feature.
In the past, I've prepared documents for this plan by preparing an MPP (NS) adoption agreement to a DC prototype, then adding the 401k feature provisions by way of a contemporaneous amendment--making the plan individually designed. We applied for and received a GUST II d-letter.
For EGTRRA, I dropped the MPP prototype and now have just a 401k PS prototype (NS). Rather than draft an individually designed plan document, I am considering adopting the plan preparing an adoption agreement to the EGTRRA 401k PS prototype (NS) that preserves the QJSA/QPSA as the default form of payout and not allowing hardships or any other in-service distributions. In the SPD, I'd also specify the fixed contribution obligation that has been part of the MPPP, despite the new governing plan documents reserving annual discretion to the employer as to what contributions to make.
My prototype was approved with language about governmental plans using it not being subject to the minimum coverage requirement provisions or the nondiscriminatory allocation provisions, and being subject to the minimum vesting provisions only to the extent not varied by an addendum to the adoption agreement.
My question is whether changing the type of plan from MPP to PS would jeopardize the grandfathering of the governmental employer having a plan with a 401k feature?
Any other concerns?
