Treatment of employers failing to meet requirements of plan

In the case of a plan maintained by more than 1 employer, this subsection shall not be treated as failing to apply to an annuity contract held under such plan merely because of one or more employers failing to meet the requirements of this subsection if such plan satisfies rules similar to the rules of section 413(e)(2) with respect to any such employer failure.

A plan shall not be treated as meeting the requirements of this subparagraph unless the plan satisfies rules similar to the rules of subparagraph (A) or (B) of section 413(e)(1), except in the case of a multiple employer plan maintained solely by any of the following: A State, a political subdivision of a State, or an agency or instrumentality of any one or more of the foregoing.
