Deposit 401(k) contributions in a timely and regular fashion. Depositing funds quickly even once may be viewed as binding by the Department of Labor and become the standard by which all other deposit times are judged for compliance.

Revise distribution forms to reflect any new regulatory requirements. Some plans are currently required to add “relative value” language regarding optional plan distribution alternatives that will require changes in the distribution forms of affected plans.

In the case of health plans, revise the plan procedures and forms to comply with new final COBRA regulations.

Review the procedures followed by the company officials who appoint your plan’s fiduciaries (typically company directors). If necessary, revise them to make sure they comply with the standards the Department of Labor articulated in high-profile cases such as Enron.

Determine whether items on the plan’s form 5500 might raise audit red flags.

Make sure the plan is in a position to impose market-based restrictions on trading if required to do so by the underlying investment or if the plan needs to do so to protect participants’ interests.

Impose and disclose in the plan’s death-benefit-beneficiary forms who the default beneficiary will be if the participant fails to name a beneficiary or if the beneficiary predeceases the participant. Make it clear that only designations contained in the plan-provided form will be reviewed to determine beneficiary status. If the form allows the naming of multiple beneficiaries, make sure it provides a default allocation among those beneficiaries if the participant fails to do so.

Make sure the plan grants the plan administrator sufficient discretion to decide benefit matters, including who is eligible and for what benefit. That way, if a denied claim is challenged in court, the court will review the plan administrator’s denial based on whether the administrator’s decision is reasonable and not on what the court would have done.
