Iowa Code Title XIII. Commerce [Chs. 505-554D] § 508C.8A. Principal place of business--determination

1. The principal place of business of a plan sponsor or a person other than a natural person shall be determined by the association in its reasonable judgment by considering all of the following factors:

2. In the case of a benefit plan sponsored by affiliated companies comprising a consolidated corporation, the principal place of business of the entity shall be deemed to be the state in which the holding company or controlling affiliate has its principal place of business as determined by the association using the factors enumerated in subsection 1. However, if more than fifty percent of the participants in the benefit plan are employed in a single state, that state shall be determined to be the principal place of business of the entity.

3. In the case of a benefit plan established or maintained by two or more employers, or jointly by one or more employers and one or more employee organizations, the principal place of business of the entity shall be deemed to be the principal place of business of the association, committee, joint board of trustees, or other similar group of representatives of the parties who establish or maintain the benefit plan. In lieu of a specific or clear designation of the principal place of business of the entity under this subsection, the principal place of business of the entity shall be deemed to be the principal place of business of the employer or employee organization that has the largest investment in the benefit plan in question.
