when to file for an initial determination

[Gudgergirl]

Company sponsored an individually designed target benefit plan - (set to amended for EGTRRA in 2011). They decided they wanted to switch to a profit-sharing plan. So they signed a volume submitter document profit-sharing document (with a minor variance from the specimen document) and merged the target benefit plan (individually designed) into the profit-sharing plan (VS)

The profit-sharing plan was effective beginning 7/1/09. I would like to get a determination letter since there is a variance from the specimen plan, but am unclear whether I need to do so by 4/30/10 (the deadline for EGTRRA Restatements for M&P and VS plans).

Can anyone point me in the right direction?
