Code of Federal Regulations Title 29. Labor § 29.4211.23 Approval of alternative method

(1) The method or modification allocates a plan's unfunded vested benefits, both for the adoption year and for the five subsequent plan years, to the same extent as any of the statutory allocation methods, or any modification to a statutory allocation method permitted under subpart B.

(2) The method or modification allocates unfunded vested benefits to each employer on the basis of either the employer's share of contributions to the plan or the unfunded vested benefits attributable to each employer. The method or modification may take into account differences in contribution rates paid by different employers and differences in benefits of different employers' employees.

(3) The method or modification fully reallocates among employers that have not withdrawn from the plan all unfunded vested benefits that the plan sponsor has determined cannot be collected from withdrawn employers, or that are not assessed against withdrawn employers because of section 4209, 4219(c)(1)(B) or 4225 of ERISA.
