When this issue is left as an open administrative function, we typically ask the contact at the firm to have the affected HCE call us for discussion. In that discussion we outline options and expected impact, directing that person call their tax advisor for counsel and then get back to us with a decision. Of course, a deadline is set for response, and a follow-up email is sent immediately after the call, covering what was discussed. If this approach is not allowed by time, or the person fails to get back to us, we discuss the issue with the Plan Administrator and make a decision on default application. Prorata is probably the safest way in the absence of a decision from the participant. Another method is in proportion to the contribution division of that person. We also have plans that are expected to fail send out a "warning notice" to the HCE, asking for them to define their preference.
