A complete or partial withdrawal of an employer (hereinafter in this section referred to as the “seller”) under this section does not occur solely because, as a result of a bona fide, arm’s-length sale of assets to an unrelated party (hereinafter in this section referred to as the “purchaser”), the seller ceases covered operations or ceases to have an obligation to contribute for such operations, if—

A complete or partial withdrawal of an employer (hereinafter in this section referred to as the “seller”) under this section does not occur solely because, as a result of a bona fide, arm’s-length sale of assets to an unrelated party (hereinafter in this section referred to as the “purchaser”), the seller ceases covered operations or ceases to have an obligation to contribute for such operations, if—

(A) the purchaser has an obligation to contribute to the plan with respect to the operations for substantially the same number of contribution base units for which the seller had an obligation to contribute to the plan;

(B) the purchaser provides to the plan for a period of 5 plan years commencing with the first plan year beginning after the sale of assets, a bond issued by a corporate surety company that is an acceptable surety for purposes of section 1112 of this title, or an amount held in escrow by a bank or similar financial institution satisfactory to the plan, in an amount equal to the greater of— (i) the average annual contribution required to be made by the seller with respect to the operations under the plan for the 3 plan years preceding the plan year in which the sale of the employer’s assets occurs, or (ii) the annual contribution that the seller was required to make with respect to the operations under the plan for the last plan year before the plan year in which the sale of the assets occurs, which bond or escrow shall be paid to the plan if the purchaser withdraws from the plan, or fails to make a contribution to the plan when due, at any time during the first 5 plan years beginning after the sale; and

(C) the contract for sale provides that, if the purchaser withdraws in a complete withdrawal, or a partial withdrawal with respect to operations, during such first 5 plan years, the seller is secondarily liable for any withdrawal liability it would have had to the plan with respect to the operations (but for this section) if the liability of the purchaser with respect to the plan is not paid.

If the purchaser—

(A) withdraws before the last day of the fifth plan year beginning after the sale, and

(B) fails to make any withdrawal liability payment when due,

If all, or substantially all, of the seller’s assets are distributed, or if the seller is liquidated before the end of the 5 plan year period described in paragraph (1)(C), then the seller shall provide a bond or amount in escrow equal to the present value of the withdrawal liability the seller would have had but for this subsection.

(A) If all, or substantially all, of the seller’s assets are distributed, or if the seller is liquidated before the end of the 5 plan year period described in paragraph (1)(C), then the seller shall provide a bond or amount in escrow equal to the present value of the withdrawal liability the seller would have had but for this subsection.

(B) If only a portion of the seller’s assets are distributed during such period, then a bond or escrow shall be required, in accordance with regulations prescribed by the corporation, in a manner consistent with subparagraph (A).

(4) The liability of the party furnishing a bond or escrow under this subsection shall be reduced, upon payment of the bond or escrow to the plan, by the amount thereof.

For the purposes of this part, the liability of the purchaser shall be determined as if the purchaser had been required to contribute to the plan in the year of the sale and the 4 plan years preceding the sale the amount the seller was required to contribute for such operations for such 5 plan years.

(1) For the purposes of this part, the liability of the purchaser shall be determined as if the purchaser had been required to contribute to the plan in the year of the sale and the 4 plan years preceding the sale the amount the seller was required to contribute for such operations for such 5 plan years.

(2) If the plan is in reorganization in the plan year in which the sale of assets occurs, the purchaser shall furnish a bond or escrow in an amount equal to 200 percent of the amount described in subsection (a)(1)(B).

The corporation may by regulation vary the standards in subparagraphs (B) and (C) of subsection (a)(1) if the variance would more effectively or equitably carry out the purposes of this subchapter. Before it promulgates such regulations, the corporation may grant individual or class variances or exemptions from the requirements of such subparagraphs if the particular case warrants it. Before granting such an individual or class variance or exemption, the corporation—

(1) shall publish notice in the Federal Register of the pendency of the variance or exemption,

(2) shall require that adequate notice be given to interested persons, and

(3) shall afford interested persons an opportunity to present their views.

For purposes of this section, the term “unrelated party” means a purchaser or seller who does not bear a relationship to the seller or purchaser, as the case may be, that is described in section 267(b) of title 26, or that is described in regulations prescribed by the corporation applying principles similar to the principles of such section.
