29 CFR § 4010.12 - Alternative method of compliance for certain sponsors of multiple employer plans.
(a) In general. Subject to paragraph (b) of this section, an eligible contributing sponsor (as defined in paragraph (c) of this section) of a multiple employer plan satisfies the requirements of this part for an information year if any contributing sponsor of the multiple employer plan provides a timely filing under this part for an information year that coincides with or overlaps with the eligible contributing sponsor's information year.
(b) PBGC request for additional information. PBGC may request some or all of the information that would otherwise be required under this part from an eligible contributing sponsor that uses the alternative method of compliance in this section. PBGC will make such a request no earlier than the date the information would otherwise have been due. The eligible contributing sponsor must provide the requested information no later than 30 days after PBGC makes the request. The requested information need not be submitted electronically.
(c) Eligible contributing sponsor. For purposes of this section, an eligible contributing sponsor of a multiple employer plan is a contributing sponsor that would not be subject to reporting if the plan were disregarded in applying the gateway tests in § 4010.4(a).
