29 C.F.R. § 2509.75-2
On February 6, 1975, the Department of Labor issued an interpretive bulletin, ERISA IB 75-2, with respect to whether a party in interest has engaged in a prohibited transaction with an employee benefit plan where the party in interest has engaged in a transaction with a corporation or partnership (within the meaning of section 7701 of the Internal Revenue Code of 1954) in which the plan has invested.
On November 13, 1986 the Department published a final regulation dealing with the definition of "plan assets". See § 2510.3-101 of this title. Under that regulation, the assets of certain entities in which plans invest would include "plan assets" for purposes of the fiduciary responsibility provisions of the Act. Section 2510.3-101 applies only for purposes of identifying plan assets on or after the effective date of that section, however, and § 2510.3-101 does not apply to plan investments in certain entities that qualify for the transitional relief provided for in paragraph (k) of that section. The principles discussed in paragraph (a) of this Interpretive Bulletin continue to be applicable for purposes of identifying assets of a plan for periods prior to the effective date of § 2510.3-101 and for investments that are subject to the transitional rule in § 2510.3-101(k) . Paragraphs (b) and (c) of this Interpretive Bulletin, however, relate to matters outside the scope of § 2510.3-101 , and nothing in that section affects the continuing application of the principles discussed in those parts.
For example, where a plan acquires a security of a corporation or a limited partnership interest in a partnership, a subsequent lease or sale of property between such corporation or partnership and a party in interest will not be a prohibited transaction solely by reason of the plan's investment in the corporation or partnership.
This general proposition, as applied to corporations and partnerships, is consistent with section 401(b)(1) of the Act, relating to plan investments in investment companies registered under the Investment Company Act of 1940. Under section 401(b)(1), an investment by a plan in securities of such an investment company may be made without causing, solely by reason of such investment, any of the assets of the investment company to be considered to be assets of the plan.
Thus, for example, if there is an arrangement under which a plan invests in, or retains its investment in, an investment company and as part of the arrangement it is expected that the investment company will purchase securities from a party in interest, such arrangement is a prohibited transaction.
Similarly, the purchase by a plan of an insurance policy pursuant to an arrangement under which it is expected that the insurance company will make a loan to a party in interest is a prohibited transaction.
Moreover, notwithstanding the foregoing, if a transaction between a party in interest and a plan would be a prohibited transaction, then such a transaction between a party in interest and such corporation or partnership will ordinarily be a prohibited transaction if the plan may, by itself, require the corporation or partnership to engage in such transaction.
Similarly, if a transaction between a party in interest and a plan would be a prohibited transaction, then such a transaction between a party in interest and such corporation or partnership will ordinarily be a prohibited transaction if such party in interest, together with one or more persons who are parties in interest by reason of such persons' relationship (within the meaning of section 3(14)(E) through (I)) to such party in interest may, with the aid of the plan but without the aid of any other persons, require the corporation or partnership to engage in such a transaction. However, the preceding sentence does not apply if the parties in interest engaging in the transaction, together with one or more persons who are parties in interest by reason of such persons' relationship (within the meaning of section 3(14)(E) through (I)) to such party in interest, may, by themselves, require the corporation or partnership to engage in the transaction.
Further, the Department of Labor emphasizes that it would consider a fiduciary who makes or retains an investment in a corporation or partnership for the purpose of avoiding the application of the fiduciary responsibility provisions of the Act to be in contravention of the provisions of section 404(a) of the Act.
