(1) The terms “employee welfare benefit plan” and “welfare plan” mean any plan, fund, or program which was heretofore or is hereafter established or maintained by an employer or by an employee organization, or by both, to the extent that such plan, fund, or program was established or is maintained for the purpose of providing for its participants or their beneficiaries, through the purchase of insurance or otherwise, (A) medical, surgical, or hospital care or benefits, or benefits in the event of sickness, accident, disability, death or unemployment, or vacation benefits, apprenticeship or other training programs, or day care centers, scholarship funds, or prepaid legal services, or (B) any benefit described in section 186(c) of this title (other than pensions on retirement or death, and insurance to provide such pensions).

Except as provided in subparagraph (B), the terms “employee pension benefit plan” and “pension plan” mean any plan, fund, or program which was heretofore or is hereafter established or maintained by an employer or by an employee organization, or by both, to the extent that by its express terms or as a result of surrounding circumstances such plan, fund, or program—

A distribution from a plan, fund, or program shall not be treated as made in a form other than retirement income or as a distribution prior to termination of covered employment solely because such distribution is made to an employee who has attained age 62 and who is not separated from employment at the time of such distribution.

(B) The Secretary may by regulation prescribe rules consistent with the standards and purposes of this chapter providing one or more exempt categories under which— (i) severance pay arrangements, and (ii) supplemental retirement income payments, under which the pension benefits of retirees or their beneficiaries are supplemented to take into account some portion or all of the increases in the cost of living (as determined by the Secretary of Labor) since retirement, shall, for purposes of this subchapter, be treated as welfare plans rather than pension plans. In the case of any arrangement or payment a principal effect of which is the evasion of the standards or purposes of this chapter applicable to pension plans, such arrangement or payment shall be treated as a pension plan.

For purposes of determinations pursuant to this paragraph, the value of any equity interest held by a person (other than such a benefit plan investor) who has discretionary authority or control with respect to the assets of the entity or any person who provides investment advice for a fee (direct or indirect) with respect to such assets, or any affiliate of such a person, shall be disregarded for purposes of calculating the 25 percent threshold. An entity shall be considered to hold plan assets only to the extent of the percentage of the equity interest held by benefit plan investors. For purposes of this paragraph, the term “benefit plan investor” means an employee benefit plan subject to part 4,[6] any plan to which section 4975 of title 26 applies, and any entity whose underlying assets include plan assets by reason of a plan’s investment in such entity.
