COBRA Responsibility in a Business Sale Depends on the Plans That Continue

Determine which plan must provide continuation coverage

The COBRA regulations contain specific rules for mergers, acquisitions, and employer withdrawals. Responsibility can depend on whether the deal is a stock or asset sale, whether the selling group continues a group health plan, and whether the buyer is a successor employer under the applicable rule. Former employees and family members can be M&A qualified beneficiaries even when they are absent from the active employee roster. A transaction should therefore have a separate continuation-coverage analysis before either side terminates its plan.

Give benefits counsel the entity groups, plans, covered people, existing COBRA elections, transaction structure, and proposed coverage dates. Do not assume that the buyer's offer of health insurance to active employees answers every beneficiary's rights. A contract can allocate administrative and economic responsibilities between the parties, but it cannot casually remove the obligations established by the regulation. The seller needs to know which plan continues, who sends notices, and what happens to beneficiaries already receiving coverage at the sale date.

Model the population that does not fit the payroll import

Assume a hypothetical seller transfers 40 active employees but also has six former employees and eight dependents with ongoing or potential continuation rights. A closing checklist covering only the 40 active workers omits fourteen people needing review. If the supported transition requires an assumed $18,000 of administrator, legal, and premium-collection work plus $30,000 of temporary funding before recoveries, the seller's first-stage cash plan needs $48,000, with later receipts tracked separately.

These are illustrative administrative and cash amounts, not COBRA premium limits or statutory liabilities. Benefits counsel and the plan administrator must determine the actual coverage and payment rules. Compare the cost of continuing a seller plan, a qualifying buyer handoff, and other supported structures only after legal responsibility is established. The owner should not approve cancellation of an insurance contract solely because all active employees accepted the buyer's offer. Existing beneficiaries and their timelines can continue beyond the operating handoff.

Reconcile coverage dates and election records

Obtain plan documents, insurance contracts, administrator agreements, employee and dependent census, qualifying-event dates, notices, elections, premium history, and pending claims. Preserve information securely using the benefits team's approved methods. A transaction financial data room is not automatically the right location for participant-level health information. The seller should retain the evidence needed to establish what notices and coverage were provided after its ordinary HR system is no longer accessible.

Prepare a person-level handoff showing the applicable plan, current status, next deadline, responsible administrator, and required completion evidence. Distinguish active coverage, elected continuation, pending elections, and unresolved premiums. A former employee whose election period is still open should not be treated as having waived coverage merely because no payment has arrived at closing. Ask the professionals to review late elections, disputed notices, and retroactive coverage scenarios rather than assuming every beneficiary can be moved on the same effective date.

Keep plan termination and successor analysis connected

The regulation's allocation rules should be applied to the actual plans and groups. If the seller retains another group health plan elsewhere, disclose it. If the buyer changes its structure or coverage immediately after closing, return that change to counsel. A successor conclusion based on an earlier deal draft may no longer fit the final arrangement. Preserve the written analysis and the facts on which it relies, including any agreement that shifts administration without changing underlying legal rights.

Before terminating accounts, verify notices, beneficiary data, payment instructions, and contact information. Assign someone to handle post-closing elections and questions. Reconcile actual premiums, reimbursements, and administrative costs to the reserve, retaining enough cash for unresolved items. The completed sale file should explain the plan responsible for each relevant beneficiary and prove that the handoff occurred. The owner can then distribute proceeds based on known remaining obligations rather than discover months later that terminating the seller's active employee plan left a separate continuation-coverage workstream unfinished.

Review insurer and administrator service boundaries explicitly. A carrier may continue paying claims while expecting the employer or another vendor to issue notices and collect premiums. Obtain written confirmation of the assigned functions, effective dates, and remaining fees so coverage continuity does not conceal an unstaffed administrative task.
