(a) General. The plan sponsor(s) of one or more plans involved in a merger or transfer, or the duly authorized representative(s) acting on behalf of the plan sponsor(s), may file a request for a determination that the transaction complies with the requirements of section 4231 of ERISA. If the plan sponsor(s) requests a compliance determination, the request must be filed with the notice of merger or transfer under § 4231.3(a)(4), and must contain the information described in paragraph (c) of this section, as applicable.

(b) Single request permitted for all de minimis transactions. A plan sponsor may submit a single request for a compliance determination covering all de minimis mergers or transfers that occur between one plan valuation and the next. However, the plan sponsor must still notify PBGC of each de minimis merger or transfer separately, in accordance with §§ 4231.8 and 4231.9. The single request for a compliance determination may be filed concurrently with any one of the notices of a de minimis merger or transfer.

(c) Contents of request. A request for a compliance determination concerning a merger or transfer that is not de minimis must contain—

(1) A copy of the merger or transfer agreement; and

(2) For each significantly affected plan, other than a plan that is a significantly affected plan only because the merger or transfer involves a plan that has terminated by mass withdrawal under section 4041A(a)(2) of ERISA, copies of all actuarial valuations performed within the 5 years preceding the date of filing the notice required under § 4231.3(a)(4).
