§
1.411(c)-1 Allocation of accrued benefits between employer and employee contributions.
(a) Accrued benefit derived from employer contributions. For purposes of section 411 and the regulations thereunder, under section 411(c)(1), an employee's accrued benefit derived from employer contributions under a plan as of any applicable date is the excess, if any, of—
(1) The total accrued benefit under the plan provided for the employee as of such date, over
(2) The accrued benefit provided for the employee, derived from contributions made by the employee under the plan as of such date.
For computation of accrued benefit derived from employee contributions to a defined contribution plan or from voluntary employee contributions to a defined benefit plan, see paragraph (b) of this section. For computation of accrued benefit derived from mandatory employee contributions to a defined benefit plan, see paragraph (c) of this section.
(b) Accrued benefit derived from employee contribution to defined contribution plan, etc. For purposes of section 411 and the regulations thereunder, under section 411(c)(2)(A) the accrued benefit derived from employee contributions to a defined contribution plan is determined under paragraph (b) (1) or (2) of this section, whichever applies. Under section 411(d)(5), the accrued benefit derived from voluntary employee contributions to a defined benefit plan is determined under paragraph (b)(1) of this section.
(1) Separate accounts maintained. If a separate account is maintained with respect to an employee's contributions and all income, expenses, gains, and losses attributable thereto, the accrued benefit determined under this subparagraph as of any applicable date is the balance of such account as of such date.
(2) Separate accounts not maintained. If a separate account is not maintained with respect to an employee's contributions and the income, expenses, gains, and losses attributable thereto, the accrued benefit determined under this subparagraph is the employee's total accrued benefit determined under the plan multiplied by a fraction—
(i) The numerator of which is the total amount of the employee's contributions under the plan less withdrawals, and
(ii) The denominator of which is the sum of (A) the amount described in paragraph (b)(2)(i) of this section, and (B) the total contributions made under the plan by the employer on behalf of the employee less withdrawals.
For purposes of this subparagraph, contributions include all amounts which are contributed to the plan even if such amounts are used to provide ancillary benefits, such as incidental life insurance, health insurance, or death benefits, and withdrawals include only amounts distributed to the employee and do not reflect the cost of any death benefits under the plan.
(c) Accrued benefit derived from mandatory employee contributions to a defined benefit plan—(1) General rule. In the case of a defined benefit plan (as defined in section 414(j)) the accrued benefit derived from contributions made by an employee under the plan as of any applicable date is an annual benefit, in the form of a single life annuity (without ancillary benefits) commencing at normal retirement age, equal to the amount of the employee's accumulated contributions (determined under paragraph (c)(3) of this section) multiplied by the appropriate conversion factor (determined under paragraph (c)(2) of this section). Paragraph (e) of this section provides rules for actuarial adjustments where the benefit is to be determined in a form other than the form described in this paragraph.
(2) Appropriate conversion factor. For purposes of this paragraph, the term “appropriate conversion factor” means the factor necessary to convert an amount equal to the accumulated contributions to a single life annuity (without ancillary benefits) commencing at normal retirement age and shall be 10 percent for a normal retirement age of 65 years. For other normal retirement ages the appropriate conversion factor shall be the factor as determined by the Commissioner.
(3) Accumulated contributions. For purposes of section 411(c) and this section, the term “accumulated contributions” means the total of—
(i) All mandatory contributions made by the employee (determined under paragraph (c)(4) of this section),
(ii) Interest (if any) on such contributions, computed at the rate provided by the plan to the end of the last plan year to which section 411(a)(2) does not apply (by reason of the applicable effective date), and
(iii) Interest on the sum of the amounts determined under paragraphs (c)(3)(i) and (ii) of this section compounded annually at the rate of 5 percent per annum from the beginning of the first plan year to which section 411(a)(2) applies (by reason of the applicable effective date) to the date on which the employee would attain normal retirement age.
For example, if under section 1017 of the Employee Retirement Income Security Act of 1974, section 411(a)(2) of the Code applies for plan years beginning after December 31, 1975, and for plan years beginning before 1975, the plan provided for 3 percent interest on employee contributions, an employee's accumulated contributions would be computed by crediting interest at the rate provided by the plan (3 percent) for plan years beginning before 1976 and by crediting interest at the rate of 5 percent (or another rate prescribed under section 411(c)(2)(D)) thereafter. Section 1017 of the Employee Retirement Income Security Act of 1974 and § 1.411(a)-2 provide the effective dates for the application of section 411(a)(2).
(4) Mandatory contributions. For purposes of section 411(c) and this section the term “mandatory contributions” means amounts contributed to the plan by the employee which are required as a condition of his employment, as a condition of his participation in the plan, or as a condition of obtaining benefits (or additional benefits) under the plan attributable to employer contributions. For example, if the benefit derived from employer contributions depends upon a specified level of employee contributions, employee contributions up to that level would be treated as mandatory contributions. Mandatory contributions, otherwise satisfying the requirements of this subparagraph, include amounts contributed to the plan which are used to provide ancillary benefits such as incidental life insurance, health insurance, or death benefits.
(d) Limitation on accrued benefit. The accrued benefit derived from mandatory employee contributions under a defined benefit plan (determined under paragraph (c) of this section) shall not exceed the greater of—
(1) The accrued benefit of the employee under the plan, or
(2) The accrued benefit derived from employee contributions determined without regard to any interest under section 411(c)(2)(C) (ii) and (iii) and under paragraphs (c)(3) (ii) and (iii) of this section.
(e) Actuarial adjustments for defined benefit plans—(1) Accrued benefit. In the case of a defined benefit plan (as defined in section 414(j)) if an employee's accrued benefit is to be determined as an amount other than an annual benefit commencing at normal retirement age, such benefit (determined under section 411(c)(1) and paragraph (a) of this section) shall be the actuarial equivalent of such benefit, as determined by the Commissioner.
(2) Accrued benefit derived from employee contributions. In the case of a defined benefit plan (as defined in section 414(j) if the accrued benefit derived from mandatory contributions made by an employee is to be determined with respect to a benefit other than an annual benefit in the form of a single life annuity (without ancillary benefits) commencing at normal retirement age, such benefit shall be the actuarial equivalent of such benefit (determined under section 411(c)(2)(B) and paragraph (c) of this section) as determined by the Commissioner.
(f) Suspension of benefits, etc.—(1) Suspensions. No adjustment to an accrued benefit is required on account of any suspension of benefits if such suspension is permitted under section 203(a)(3)(B) of the Employee Retirement Income Security Act of 1974 (88 Stat. 855) (Code section 411(a)(3)(B)).
(2) Employment after retirement. No actuarial adjustment to an accrued benefit is required on account of employment after normal retirement age. For example, if a plan with a normal retirement age of 65 provides a benefit of $400 a month payable at age 65 the same $400 benefit (with no upward adjustment) could be paid to an employee who retires at age 68.
