"Looking at a plan doc prepared by another. Calendar year plan.

Eligibility for the 401(k) component is 6 months in which at least 1,000 hours of service are required, with the 401(k) component's entry date being the first month following completion of 6 months. Can a 401(k) plan require 1,000 hours of service in a 6-month period, for the 401(k) component?

For the employer's profit-sharing contribution componennt, the participant must have 12 months with 1,000 hours, so that seems fine. (Entry date is dual entry, 1st and 7th months.)"
