Employer Statutory Social Security Allocation in Asset Deals
Statutory social security debts automatically attach to acquired assets, requiring specific completion statement deductions and dedicated long-term escrows.
ERISA Section 4204
Meaning
Statutory safe-harbor provisions under U.S. pension law exempt asset sales from triggering immediate multiemployer pension withdrawal liability for the selling employer. Application of ERISA section 4204 requires the purchaser of corporate assets to assume a continuing obligation to contribute to the pension plan for substantially the same number of base contribution units as the seller had contributed previously. The statutory mechanism replaces the seller with the buyer inside the pension plan contribution structure, preventing an asset sale from being treated as a complete or partial withdrawal.
The statutory exemption fails if the purchaser fails to provide required financial bonds or if the transaction lacks commercial substance outside tax avoidance.
Exemption Requirement
Asset purchase agreements must incorporate specific statutory conditions to prevent liability assessment against the seller. Reliance on ERISA section 4204 mandates that the buyer commits to ongoing plan contributions and posts an escrow deposit or bank letter of credit to secure potential withdrawal obligations. The sale contract must also state that if the buyer withdraws from the plan within five years following closing, the seller remains secondarily liable for any withdrawal liability assessment.
Purchaser Bond
Securing statutory protection requires the buyer to provide financial collateral to pension plan trustees. Compliance with ERISA section 4204 dictates that the purchaser posts a bond or escrow amount equal to five years of historical plan contributions paid by the seller. This financial assurance remains in place for five plan years following transaction completion, protecting the pension fund against purchaser default.
Variance waivers may be sought from the pension plan if the purchaser demonstrates financial strength satisfying statutory net worth ratios.
Seller Liability
Secondary obligation rules preserve plan recourse against the selling entity during the post-transaction transition window. Under ERISA section 4204, if the buyer defaults on its contribution duties or triggers a plan withdrawal within the initial five-year period, the seller must pay its historical share of withdrawal liability. Transaction documents manage this secondary risk through indemnification clauses and indemnities secured by holdback escrows.
The statutory mechanism protects multiemployer pension plans while enabling corporate asset sales to proceed without immediate withdrawal penalties.
