### §1321. Coverage

#### (a) Plans covered

Except as provided in subsection (b), this subchapter applies to any plan (including a successor plan) which, for a plan year—

(1) is an employee pension benefit plan (as defined in paragraph (2) of section 1002 of this title) established or maintained—

(A) by an employer engaged in commerce or in any industry or activity affecting commerce, or

(B) by any employee organization, or organization representing employees, engaged in commerce or in any industry or activity affecting commerce, or

(C) by both,

which has, in practice, met the requirements of part I of subchapter D of chapter 1 of title 26 (as in effect for the preceding 5 plan years of the plan) applicable to the plans described in paragraph (2) for the preceding 5 plan years; or

(2) is, or has been determined by the Secretary of the Treasury to be, a plan described in section 401(a) of title 26, or which meets, or has been determined by the Secretary of the Treasury to meet, the requirements of section 404(a)(2) of title 26.

For purposes of this subchapter, a successor plan is considered to be a continuation of a predecessor plan. For this purpose, unless otherwise specifically indicated in this subchapter, a successor plan is a plan which covers a group of employees which includes substantially the same employees as a previously established plan, and provides substantially the same benefits as that plan provided.

#### (b) Plans not covered

(4)(A) established and maintained by a society, order, or association described in section 501(c)(8) or (9) of title 26, if no part of the contributions to or under the plan is made by employers of participants in the plan, or

(B) of which a trust described in section 501(c)(18) of title 26 is a part;

(5) which has not at any time after September 2, 1974, provided for employer contributions;

(6) which is unfunded and which is maintained by an employer primarily for the purpose of providing deferred compensation for a select group of management or highly compensated employees;

(8) which is maintained by an employer solely for the purpose of providing benefits for certain employees in excess of the limitations on contributions and benefits imposed by section 415 of title 26 on plans to which that section applies, without regard to whether the plan is funded, and, to the extent that a separable part of a plan (as determined by the corporation) maintained by an employer is maintained for such purpose, that part shall be treated for purposes of this subchapter, as a separate plan which is an excess benefit plan;

(9) which is established and maintained exclusively for substantial owners;

(10) of an international organization which is exempt from taxation under the International Organizations Immunities Act [22 U.S.C. 288 et seq.];

(11) maintained solely for the purpose of complying with applicable workmen's compensation laws or unemployment compensation or disability insurance laws;
