(a) Definition. The benefits in priority category 3 are those annuity benefits that were in pay status before the beginning of the 3-year period ending on the termination date, and those annuity benefits that could have been in pay status (then or as of the next payment date under the plan's rules for starting benefit payments) for participants who, before the beginning of the 3-year period ending on the termination date, had reached their Earliest PBGC Retirement Date (as determined under
§ 4022.10 of this chapter based on plan provisions in effect on the day before the beginning of the 3-year period ending on the termination date). Benefit increases that were effective throughout the 5-year period ending on the termination date, including automatic benefit increases during that period to the extent provided in
paragraph (b)(5) of this section, shall be included in determining the priority category 3 benefit. Benefits are primarily basic-type benefits, although nonbasic-type benefits will be included if any portion of a participant's priority category 3 benefit is not guaranteeable under the provisions of subpart A of part 4022 and
§ 4022.21 of this chapter.
