(2) in the case of a vested participant who dies before the annuity starting date and who has a surviving spouse, a qualified preretirement survivor annuity shall be provided to the surviving spouse of such participant.

This section shall apply to—

This section shall apply to—

(A) any defined benefit plan,

(B) any individual account plan which is subject to the funding standards of section 1082 of this title, and

(C) any participant under any other individual account plan unless— (i) such plan provides that the participant’s nonforfeitable accrued benefit (reduced by any security interest held by the plan by reason of a loan outstanding to such participant) is payable in full, on the death of the participant, to the participant’s surviving spouse (or, if there is no surviving spouse or the surviving spouse consents in the manner required under subsection (c)(2), to a designated beneficiary), (ii) such participant does not elect the payment of benefits in the form of a life annuity, and (iii) with respect to such participant, such plan is not a direct or indirect transferee (in a transfer after December 31, 1984) of a plan which is described in subparagraph (A) or (B) or to which this clause applied with respect to the participant.

In the case of—

(A) In the case of— (i) a tax credit employee stock ownership plan (as defined in section 409(a) of title 26), or (ii) an employee stock ownership plan (as defined in section 4975(e)(7) of title 26), subsection (a) shall not apply to that portion of the employee’s accrued benefit to which the requirements of section 409(h) of title 26 apply.

(B) Subparagraph (A) shall not apply with respect to any participant unless the requirements of clause [1] (i), (ii), and (iii) of paragraph (1)(C) are met with respect to such participant.

(4)  [2] This section shall not apply to a plan which the Secretary of the Treasury or his delegate has determined is a plan described in section 404(c) of title 26 (or a continuation thereof) in which participation is substantially limited to individuals who, before January 1, 1976, ceased employment covered by the plan.

(4)  2 A plan shall not be treated as failing to meet the requirements of paragraph (1)(C) or (2) merely because the plan provides that benefits will not be payable to the surviving spouse of the participant unless the participant and such spouse had been married throughout the 1-year period ending on the earlier of the participant’s annuity starting date or the date of the participant’s death.

A plan meets the requirements of this section only if—

A plan meets the requirements of this section only if—

(B) requirements comparable to the requirements of paragraph (2) are met with respect to such consent.

The requirements of this subsection shall not apply with respect to the qualified joint and survivor annuity form of benefit or the qualified preretirement survivor annuity form of benefit, as the case may be, if such benefit may not be waived (or another beneficiary selected) and if the plan fully subsidizes the costs of such benefit.

(A) The requirements of this subsection shall not apply with respect to the qualified joint and survivor annuity form of benefit or the qualified preretirement survivor annuity form of benefit, as the case may be, if such benefit may not be waived (or another beneficiary selected) and if the plan fully subsidizes the costs of such benefit.

(B) For purposes of subparagraph (A), a plan fully subsidizes the costs of a benefit if under the plan the failure to waive such benefit by a participant would not result in a decrease in any plan benefits with respect to such participant and would not result in increased contributions from such participant.

(A) relying on a consent or revocation referred to in paragraph (1)(A), or

(B) making a determination under paragraph (2),

In any case to which this subparagraph applies, the applicable election period under paragraph (7) shall not end before the 30th day after the date on which such explanation is provided. (ii) The Secretary of the Treasury may by regulations limit the application of clause (i), except that such regulations may not limit the period of time by which the annuity starting date precedes the provision of the written explanation other than by providing that the annuity starting date may not be earlier than termination of employment.

(B) A plan may permit a participant to elect (with any applicable spousal consent) to waive any requirement that the written explanation be provided at least 30 days before the annuity starting date (or to waive the 30-day requirement under subparagraph (A)) if the distribution commences more than 7 days after such explanation is provided.
