A wave of roughly 100 lawsuits has been moving through the federal courts over a corner of 401(k) plumbing most savers have never heard of: what happens to employer match dollars left behind by workers who quit before vesting. On May 12, 2026, the first of them reached a federal appeals court — and the decision is a useful reminder that the money in dispute only exists because someone walked away from it.
What the Cases Are Actually About
When an employee leaves before the employer match fully vests, the unvested dollars are forfeited back to the plan. They do not vanish, and they do not go back into the company's operating account. The plan then uses them one of two ways: to pay the plan's administrative expenses, or to offset the employer's future matching contributions.
Plaintiffs across these suits argue that choosing the second option breaches ERISA's fiduciary duty, because paying expenses out of forfeitures would lower costs for the remaining participants, while offsetting contributions mainly benefits the employer. The Department of Labor has taken the employers' side, filing an amicus brief urging dismissal.
The Eighth Circuit Ruling
In Matula v. Wells Fargo & Co., the Eighth Circuit affirmed dismissal — but on standing, not on the merits. Wells Fargo matches up to 6% of pay, vesting over three years; employees who leave earlier forfeit the unvested portion. The court found that the plaintiff never alleged the company's handling of forfeitures caused any injury to his own account, a gap his attorney acknowledged at oral argument. The dismissal was without prejudice, leaving room to replead.
So the central legal question is still open. Hutchins v. HP Inc. was argued before the Ninth Circuit in May, and Cain v. Siemens Corp. is pending in the Third. If those courts disagree, the Supreme Court could eventually take it up. Meanwhile, district courts have mostly sided with employers — Donelson v. Meijer was dismissed in part because the plan document expressly permitted either use, which is how most plans are written.
What This Means for Your Own Account
The honest answer is that the outcome will barely move any individual balance. Forfeiture money is spread across a whole plan; even a win for participants shows up as marginally lower recordkeeping fees, not a deposit. The far larger number is the match you forfeit yourself by leaving early — and that one is entirely within your control.
Practical takeaways:
- Read your vesting schedule before you read the headlines. It is in your Summary Plan Description. Cliff vesting means you get 0% until a date and 100% after it — leaving one month early can cost the entire match. Graded vesting releases the money in slices, typically over three to six years.
- Your own contributions are always 100% yours. Only employer match and profit-sharing dollars can be forfeited. Nothing you deferred from your paycheck is ever at risk.
- Time a job change around the vesting date when you can. If you are weeks away from a cliff, negotiating a later start date is often worth more than a signing bonus.
- A rollover cannot recover forfeited money. Once unvested dollars go back to the plan, rolling your balance to an IRA or a new 401(k) does not bring them along.
- Returning to a former employer may restore service credit. Many plans count prior service toward vesting after a rehire. If you are boomeranging back, ask before you assume the clock restarted.
Watch the Ninth and Third Circuits for the legal resolution. Watch your Summary Plan Description for the part that affects your money.
