What are the minimum funding standards under ERISA?

A plan shall be treated as satisfying the minimum funding standard for a plan year if:

1.    In the case of a defined benefit plan that is not a multiemployer plan, the employer makes contributions to or under the plan for the plan year that, in the aggregate, are not less than the minimum required contribution determined under IRC Section 430 for the plan for the plan year;

2.    In the case of a money purchase plan that is not a multiemployer plan, the employer makes contributions to or under the plan for the plan year that are required under the terms of the plan;

3.    In the case of a multiemployer plan, the employers make contributions to or under the plan for any plan year that, in the aggregate, are sufficient to ensure that the plan does not have an accumulated funding deficiency under IRC Section 431 as of the end of the plan year.
