Final answer:
If participant loans in a 401(k) plan are found to be delinquent, the trustee's account administrator should notify the Named Fiduciary who is responsible for administering the loan program.
Step-by-step explanation:
When conducting an audit or compliance review and noticing that several participant loans are delinquent in a 401(k) plan, the correct recommendation for the trustee's account administrator is to notify the Named Fiduciary who administers the loan program.
This step is essential because the Named Fiduciary has the responsibility to address the issue and take appropriate action, which could include restructuring the loan, commencing the collections process, or considering the delinquent loans as taxable distributions if necessary. Handling such matters is part of the fiduciary duties to ensure the plan is operating according to legal requirements and serves the best interests of the participants.
