How often courts cite this section
Court decisions citing this, by year.Markers show enactment, consequential amendments, and circuit splits over this section — watch for a citation surge after a change or a disagreement. The dip in the last several years is a data-coverage gap, not a real trend — our corpus holds fewer opinions from the most recent years, so recent citations are undercounted.
Except in the case of a plan amended under subsection (b) of this section, the amount of the unfunded vested benefits allocable under section 1391 of this title to an employer who withdraws from a plan shall be reduced by the smaller of—
(1) 3/4 of 1 percent of the plan's unfunded vested obligations (determined as of the end of the plan year ending before the date of withdrawal), or
(2) $50,000,
reduced by the amount, if any, by which the unfunded vested benefits allowable to the employer, determined without regard to this subsection, exceeds $100,000.
A plan may be amended to provide for the reduction of the amount determined under section 1391 of this title by not more than the greater of—
(1) the amount determined under subsection (a) of this section, or
(2) the lesser of—
(A) the amount determined under subsection (a)(1) of this section, or
(B) $100,000,
reduced by the amount, if any, by which the amount determined under section 1391 of this title for the employer, determined without regard to this subsection, exceeds $150,000.
This section does not apply—
(1) to an employer who withdraws in a plan year in which substantially all employers withdraw from the plan, or
(2) in any case in which substantially all employers withdraw from the plan during a period of one or more plan years pursuant to an agreement or arrangement to withdraw, to an employer who withdraws pursuant to such agreement or arrangement.
In any action or proceeding to determine or collect withdrawal liability, if substantially all employers have withdrawn from a plan within a period of 3 plan years, an employer who has withdrawn from such plan during such period shall be presumed to have withdrawn from the plan pursuant to an agreement or arrangement, unless the employer proves otherwise by a preponderance of the evidence.
