We have a client, Company A, who sponsored a safe harbor match 401(k) plan. The plan is top heavy for 2019. On 10/01/2019 Company A sold all Company A's assets to Company B. All the owners of Company A became employees of Company B and have no ownership in Company B. Effective with the assets sale on 10/01/2019, Company B took over sponsorship of Company A's 401(k) plan. Going into 2020 Company B would like to amend eligibility to be immediate upon date of hire for salary deferrals but still require 1 year of service to receive the safe harbor match. Would the plan be considered top heavy for 2020 requiring that participants eligible to defer but not eligible for the safe harbor match be given a top heavy benefit?
