Key takeaways

  • Termination follows the plan document and applicable law.
  • Excess 401(h) assets are governed by specific statutory rules.
  • Participants must be informed appropriately.
  • ERISA counsel and the actuary lead the process.

Why sponsors terminate

Sale of the business, change in benefit philosophy, or restructuring of the underlying qualified plan all can trigger termination of the 401(h) feature. The reason shapes the process.

Handling sub-account assets

Statutory rules govern what happens to assets that exceed obligations on termination. Coordination with the actuary and ERISA counsel is essential — improvisation here is expensive.

Communications and reporting

Participants and beneficiaries need clear notice. Form 5500 and related reporting should reflect the termination accurately.

Frequently asked questions

Reversion is governed by specific statutory rules and is not the default outcome. Counsel-driven.
