of a weighting factor based on the credibility of the plan’s experience.

(2) Controlled group consistency requirement . The regulations provide certain exceptions to the general rule under § 430(h)(3)(C)(iv) and § 1.430(h)(3)-2(c) (1)(i), under which a plan sponsor may not use substitute mortality tables for any plan for a plan year unless substitute mortality tables are established and used for each other plan subject to § 430 that is maintained by the plan sponsor or a member of the plan sponsor’s controlled group (as defined in § 1.430(h)(3)-2(c)(1)(i)) for that plan year. Under § 1.430(h)(3)-2(c)(1)(ii), the use of substitute mortality tables for one plan is not prohibited merely because another plan maintained by the plan sponsor (or by a member of the plan sponsor’s controlled group) may not use substitute mortality tables because neither the males nor the females under that other plan have credible mortality information for a plan year. In addition, under § 1.430(h)(3)-2(f), the regulations provide a transition period for newly affiliated plans.

(3) Treatment of disabled individuals . If separate mortality tables are used for disabled individuals pursuant to § 430(h) (3)(D), then those individuals are disregarded for all purposes under this revenue procedure.

(4) Treatment of multiple-employer plans . A multiple-employer plan for which the proportion of the plan’s funding target attributable to employees and former employees of the employer and members of the employer’s controlled group is greater than 50 percent is treated as maintained by that employer for purposes of the controlled group consistency requirement pursuant to § 1.430(h)(3)-2(c)(7)(ii). By contrast, any other multiple-employer plan in which the employer or a member of the employer’s controlled group participates is not treated as maintained by the employer for purposes of the controlled group consistency requirement and is disregarded under this revenue procedure.

.03 Amendments to regulations relating to substitute mortality tables . TD 10005 includes amendments to the rules used to construct substitute mortality tables under
