§ 4211.31 Allocation of unfunded vested benefits following the merger of plans.
(a) General rule. Except as provided in paragraphs (b) through (d) of this section, when two or more multiemployer plans merge, the merged plan shall adopt one of the statutory allocation methods, in accordance with subpart B of this part, or one of the allocation methods prescribed in §§ 4211.32 through 4211.35, and the method adopted shall apply to all employer withdrawals occurring after the initial plan year. Alternatively, a merged plan may adopt its own allocation method in accordance with subpart C of this part. If a merged plan fails to adopt an allocation method pursuant to this subpart or subpart B or C, it shall use the presumptive allocation method prescribed in § 4211.32. In addition, a merged plan may adopt any of the modifications prescribed in § 4211.36 or in subpart B of this part.
