127. An improvement unfunded actuarial liability may be considered to be an initial unfunded actuarial liability if the amendment from which it arises provides only for the crediting of service in respect of a period prior to the effective date of the plan or, in the case of a multi-employer plan, even a plan not considered to be a multi-employer plan pursuant to section 11, in respect of a period prior to the date of coming into force of an amendment to provide for the participation of a new employer. In the latter case, however, the unfunded liability must pertain only to the crediting of service to members who were employed by the new employer.
