29 C.F.R. § 2510.3-3 — Employee benefit plan.

(b) Plans without employees. For purposes of title I of the Act and this chapter, the term “employee benefit plan” shall not include any plan, fund or program, other than an apprenticeship or other training program, under which no employees are participants covered under the plan, as defined in paragraph (d) of this section. For example, a so-called “Keogh” or “H.R. 10” plan under which only partners or only a sole proprietor are participants covered under the plan will not be covered under title I. However, a Keogh plan under which one or more common law employees, in addition to the self-employed individuals, are participants covered under the plan, will be covered under title I. Similarly, partnership buyout agreements described in section 736 of the Internal Revenue Code of 1954 will not be subject to title I.

(1) Whether the individual is entitled to benefits under the plan, or

(2) The amount of benefits to which the individual is entitled,

whichever results in earlier participation.

(2)

(i) An individual is not a participant covered under an employee welfare plan on the earliest date on which the individual -

(A) Is ineligible to receive any benefit under the plan even if the contingency for which such benefit is provided should occur, and

(B) Is not designated by the plan as a participant.

(2) A contract, policy or certificate describing the benefits to which the individual is entitled under the plan has been issued to the individual; or

(B) The individual has received from the plan a lump-sum distribution or a series of distributions of cash or other property which represents the balance of his or her credit under the plan.

(3)

(i) In the case of an employee pension benefit plan, an individual who, under the terms of the plan, has incurred a one-year break in service after having become a participant covered under the plan, and who has acquired no vested right to a benefit before such break in service is not a participant covered under the plan until the individual has completed a year of service after returning to employment covered by the plan.

(ii) For purposes of paragraph (d)(3)(i) of this section, in the case of an employee pension benefit plan which is subject to section 203 of the Act the term “year of service” shall have the same meaning as in section 203(b)(2)(A) of the Act and any regulations issued under the Act and the term “one-year break in service” shall have the same meaning as in section 203(b)(3)(A) of the Act and any regulations issued under the Act.
