Sec. 1.412(c)(3)-1  Reasonable funding methods.

    (a) Introduction--(1) In general. This section prescribes rules for 
determining whether or not, in the case of an ongoing plan, a funding 
method is reasonable for purposes of section 412(c)(3). A method is 
unreasonable only if it is found to be inconsistent with a rule 
prescribed in this section. The term ``reasonable funding method'' under 
this section has the same meaning as the term ``acceptable actuarial 
cost method'' under section 3(31) of the Employee Retirement Income 
Security Act of 1974 (ERISA).
    (2) Computations included in method. See Sec. 1.412(c)(1)-1(b) for 
a discussion of matters that are, and are not, included in the funding 
method of a plan.
    (3) Plans using shortfall. The shortfall method is a method of 
determining charges to the funding standard account by adapting the 
underlying funding method of certain collectively bargained plans in the 
manner described in Sec. 1.412(c)(1)-2. As such, the shortfall method 
is a funding method. The underlying method of a plan that uses the 
shortfall method must be a reasonable funding method under this section. 
The rules contained in this section, relating to cost under a reasonable 
funding method, apply in the shortfall method to the annual computation 
charge under Sec. 1.412(c)(1)-2(d).
    (4) Scope of funding method. Except for the shortfall method, a 
reasonable funding method is applied to the computation of--
    (i) The normal cost of a plan for a plan year; and, if applicable,
    (ii) The bases established under section 412(b)(2)(B), (C), and (D), 
and (3) (B) (``amortizable bases'').
    (b) General rules for reasonable funding methods--(1) Basic funding 
formula. At any time, except as provided by the Commissioner, the 
present value of future benefits under a reasonable funding method must 
equal the sum of the following amounts:
    (i) The present value of normal costs (taking into account future 
mandatory employee contributions, within the meaning of section 
411(c)(2)(C), in the case of a contributory plan) over the future 
working lifetime of participants;
    (ii) The sum of the unamortized portions of amortizable bases, if 
any, treating credit bases under section 412(b)(3)(B) as negative 
numbers; and
    (iii) The plan assets, decreased by a credit balance (and increased 
by a debit balance) in the funding standard account under section 
412(b).
    (2) Normal cost. Normal cost under a reasonable funding method must 
be expressed as--
    (i) A level dollar amount, or a level percentage of pay, that is 
computed from year to year on either an individual basis or an aggregate 
basis; or
    (ii) An amount equal to the present value of benefits accruing under 
the method for a particular plan year.
    (3) Application to shortfall. Paragraph (b)(2) will not fail to be 
satisfied merely because an amount described in (i) or (ii) is expressed 
as permitted under the shortfall method.
    (c) Additional requirements--(1) Inclusion of all liabilities. Under 
a reasonable funding method, all liabilities of the plan for benefits, 
whether vested or not, must be taken into account.
    (2) Production of experience gains and losses. If each actuarial 
assumption is exactly realized under a reasonable funding method, no 
experience gains or losses are produced.
    (3) Plan population--(i) In general. Under a reasonable funding 
method, the plan population must include three classes of individuals: 
participants currently employed in the service of the

[[Page 666]]

employer; former participants who either terminated service with the 
employer, or retired, under the plan; and all other individuals 
currently entitled to benefits under the plan. See Sec. 1.412(c)(3)-
1(d)(2) for rules concerning anticipated future participants.
    (ii) Limited exclusion for certain recent participants. Under a 
reasonable funding method, certain individuals may be excluded from the 
first class of individuals described in paragraph (c)(3)(i) of this 
section unless otherwise provided by the Commissioner. The excludable 
individuals are participants who would be excluded from participation by 
the minimum age or service requirement of section 410 but who, under the 
terms of the plan, participate immediately upon entering the service of 
the employer.
    (iii) Special exclusion for ``rule of parity'' cases. Under a 
reasonable funding method, certain individuals may be excluded from the 
second class of individuals described in paragraph (c)(3)(i) of this 
section. The excludable individuals are those former participants who 
have terminated service with the employer without vested benefits and 
whose service might be taken into account in future years because the 
``rule of parity'' of section 411(a)(6)(D) does not permit that service 
to be disregarded. However if the plan's experience as to separated 
employees' returning to service has been such that the exclusion 
described in this subparagraph would be unreasonable, the exclusion 
would no longer apply.
    (4) Use of salary scale--(i) General acceptability. The use of a 
salary scale assumption is not inappropriate merely because of the 
funding method with which it is used. Therefore, in determining whether 
actuarial assumptions are reasonable, a salary scale will not be 
considered to be prohibited merely because a particular funding method 
is being used.
    (ii) Projection to appropriate salary. Under a reasonable funding 
method, salary scales reflected in projected benefits must be the 
expected salary on which benefits would be based under the plan at the 
age when the receipt of benefits is expected to begin.
    (5) Treatment of allocable items. Under a reasonable funding method 
that allocates assets to individual participants to determine costs, the 
allocation of assets among participants must be reasonable. An initial 
allocation of assets among participants will be considered reasonable 
only if it is in proportion to related liabilities. However, the 
Commissioner may determine, based on the facts and circumstances, that 
it is unreasonable to continue to allocate assets on this basis beyond 
the initial year. Under a reasonable funding method that allocates 
liabilities among different elements of past and future service, the 
allocation of liabilities must be reasonable.
    (d) Prohibited considerations under a reasonable funding method--(1) 
Anticipated benefit changes--(i) In general. Except as otherwise 
provided by the Commissioner, a reasonable funding method does not 
anticipate changes in plan benefits that become effective, whether or 
not retroactively, in a future plan year or that become effective after 
the first day of, but during, a current plan year.
    (ii) Exception for collectively bargained plans. A collectively 
bargained plan described in section 413(a) may on a consistent basis 
anticipate benefit increases scheduled to take effect during the term of 
the collective-bargaining agreement applicable to the plan. A plan's 
treatment of benefit increases scheduled in a collective bargaining 
agreement is part of its funding method. Accordingly, a change in a 
plan's treatment of such benefit increases (for example, ignoring 
anticipated increases after taking them into account) is a change of 
funding method.
    (2) Anticipated future participants. A reasonable funding method 
must not anticipate the affiliation with the plan of future participants 
not employed in the service of the employer on the plan valuation date. 
However, a reasonable funding method may anticipate the affiliation with 
the plan of current employees who have not satisfied the participation 
requirements of the plan.
    (e) Special rules for certain funding methods--(1) Applicability of 
special rules. Paragraph (e) of this section applies to a funding method 
that determines normal cost under paragraph (b)(2)(ii) of this section.

[[Page 667]]

    (2) Use of salary scale. For rules relating to use of a salary scale 
assumption, see paragraph (c)(4) of this section.
    (3) Allocation of liabilities. In determining a plan's normal cost 
and accrued liability for a particular plan year, the projected benefits 
of the plan must be allocated between past years and future years. 
Except in the case of a career average pay plan, this allocation must be 
in proportion to the applicable rates of benefit accrual under the plan. 
Thus, the allocation to past years is effected by multiplying the 
projected benefit by a fraction. The numerator of the fraction is the 
participant's credited years of service. The denominator is the 
participant's total credited years of service at the anticipated benefit 
commencement date. Adjustments are made to account for changes in the 
rate of benefit accrual. An allocation based on compensation is not 
permitted. In the case of a career average pay plan, an allocation 
between past and future service benefits must be reasonable.
    (f) Treatment of ancillary benefit costs--(1) General rule. Under a 
reasonable funding method, except as otherwise provided by this 
paragraph (f), ancillary benefit costs must be computed by using the 
same method used to compute retirement benefit costs under a plan.
    (2) Ancillary benefit defined. For purposes of this paragraph an 
ancillary benefit is a benefit that is paid as a result of a specified 
event which--
    (i) Occurs not later than a participant's separation from service, 
and
    (ii) Was detrimental to the participant's health.


Thus, for example, benefits payable if a participant dies or becomes 
disabled prior to separation from service are ancillary benefits because 
the events giving rise to the benefits are detrimental to the 
participant's health. However, an early retirement benefit, a social 
security supplement (as defined in Sec. 1.411(a)-7(c)(4)(ii)), and the 
vesting of plan benefits (even if more rapid than is required by section 
411) are not ancillary benefits because those benefits do not result 
from an event which is detrimental to the participant's health.
    (3) Exception for certain insurance contracts. Under a reasonable 
funding method, regardless of the method used to compute retirement 
benefit costs, the cost of an ancillary benefit may equal the premium 
paid for that benefit under an insurance contract if--
    (i) The ancillary benefit is provided under the contract, and
    (ii) The benefit is guaranteed under the contract.
    (4) Exception for 1-year term funding and other approved methods. 
[Reserved]
    (5) Section 401(h) benefits. Section 412 does not apply to benefits 
that are described in section 401(h) and for which a separate account is 
maintained.
    (g) Examples. The principles of this section are illustrated by the 
following examples:

    Example (1). Assume that a plan, using funding method A, is in its 
first year. No contributions have been made to the plan, other than a 
nominal contribution to establish a corpus for the plan's trust. There 
is no past service liability, and the normal cost is a constant 
percentage of an annually determined amount. The constant percentage is 
99 percent, and the annually determined amount is the excess of the 
present value of future benefits over plan assets. The present value of 
future benefits is $10,000. Under paragraph (b)(1) of this section, the 
present value of future benefits must equal the present value of future 
normal costs plus plan assets. (No amortizable bases exist, nor are 
there credit or debit balances.) Under method A, the present value of 
future normal costs would equal the sum of a series of annually 
decreasing amounts. Because of the constant percentage factor, the 
present value of future normal costs over the years can never equal 
$10,000, the present value of future benefits. In effect, then, assets 
under method A can never equal the present value of future benefits if 
all assumptions are exactly realized. Therefore, method A is not a 
reasonable funding method.
    Example (2). Assume that a plan, using funding method B, determines 
normal cost by computing the present value of benefits expected to be 
accrued under the plan by the end of 10 years after the valuation date 
and adding to this the present value of benefits expected to be paid 
within these 10 years. Plan assets are subtracted from the sum of the 
two present value amounts. The difference then is divided by the present 
value of salaries projected over the 10 years. Under paragraph (c)(1) of 
this section, all liabilities of a plan must be taken into account. 
Because method B takes into account only benefits paid or accrued by the 
end of 10 years, it is not a reasonable funding method.

[[Page 668]]

    Example (3). Assume that a plan, using funding method C, determines 
normal cost as a constant percentage of compensation. (This percentage 
is determined as follows: The excess of projected benefits over accrued 
benefits is computed. Then the present value of this excess is divided 
by the present value of future salaries.) However, the accrued liability 
is computed each year as the present value of accrued benefits. (This 
computation does not reflect normal cost as a constant percentage of 
compensation. Thus, normal cost under the plan does not link accrued 
liabilities under the plan for consecutive years as would be the case, 
for example, under a unit credit cost method.) In determining gains and 
losses, method C compares the actual unfunded liability (the accrued 
liability less assets) with the expected unfunded liability (the sum of 
the actual unfunded liability in the previous year and the normal cost 
for the previous year less the contribution made for the previous year, 
all adjusted for interest). Under paragraph (c)(2) of this section, if 
actuarial assumptions are exactly realized, experience gains and losses 
must not be produced. Under method C, the use of a constant percentage 
in computing normal cost (and the expected unfunded liability) coupled 
with the manner of computing the accrued liability (and the actual 
unfunded liability) generally produces gains in the earlier years and 
losses in the later years if each actuarial assumption is exactly 
realized. Therefore, method C is not a reasonable funding method.
    Example (4). Assume that a plan, using funding method D, bases 
benefits on final average pay. Under method D, the past service 
liability on any date equals the present value of the accrued benefit on 
that date based on compensation as of that date. The normal cost for any 
year equals the present value of a certain amount. That amount is the 
excess of the projected accrued benefit as of the end of the year over 
the actual accrued benefit at the beginning of the year. Accrued 
benefits, projected as of the end of a year, reflect a 1-year salary 
projection. Under paragraph (c)(4) of this section, salary scales 
reflected in projected benefits must project salaries to the salary on 
which benefits would be based under the plan at the age when the receipt 
of benefits under the plan is expected to begin. Because the plan is not 
a career average pay plan and compensation is projected only 1 year, 
method D is not a reasonable funding method. (Under paragraph (c)(4) of 
this section, the use of a salary scale assumption could be required 
with a unit credit method if, without the use of a salary scale, 
assumptions in the aggregate are unreasonable.)
    Example (5). Assume that a plan, using method E, a unit credit 
funding method, calculates a participant's accrued benefit according to 
the following formula: 2 percent of final salary for the first 10 years 
of service and 1 percent of final salary for the years of service in 
excess of 10. Under the plan, no employee may be credited with more than 
25 years of service. The actuarial assumptions for the valuation include 
a salary scale of 5 percent per year. For a participant at age 40 with 
15 years of service, a current salary of $20,000 and a normal retirement 
age of 65, the accrued liability for the retirement benefit is the 
present value of an annuity of $16,932 per year, commencing at age 65. 
The $16,932 is calculated as follows:
[GRAPHIC] [TIFF OMITTED] TC14NO91.161


(3.3864 is 1.05 raised to the 25th power; the 25th power reflects the 
difference between normal retirement age and attained age (65-40).)
    Salary under this method is projected to the age when the receipt of 
benefits is expected to begin. Therefore, method E meets the requirement 
of paragraph (c)(4) of this section. Also, the allocation of benefits 
under method E between past and future years of service meets the 
requirements of paragraph (e)(3) of this section.
    Example (6). Assume that a plan that has two participants and that 
previously used the unit credit cost method wishes to change the funding 
method at the beginning of the plan year to funding method F, a 
modification of the aggregate cost method. The modification involves 
determining normal cost for each of the two participants under the plan. 
Therefore, it requires an allocation of assets to each participant for 
valuation purposes. The actuary proposes to allocate the assets on hand 
at the beginning of the plan year of the change in funding method in 
proportion to the accrued liabilities calculated under the unit credit 
cost method. The relevant results of the calculations are shown below:

------------------------------------------------------------------------
                                                    Employees
                                                ----------------  Totals
                                                    M       N
------------------------------------------------------------------------
Accrued Liabilities (unit credit method):
  Dollar amount................................   15,670    906   16,576
  Per cent of total............................    94.53   5.47   100.00

[[Page 669]]


Assets:
  Dollar amount................................    7,835    453    8,288
  per cent of total............................    94.53   5.47   100.00
------------------------------------------------------------------------

    The proposed allocation in proportion to the accrued liabilities 
under the unit credit cost method satisfies the requirements of 
paragraph (c)(5) of this section at the beginning of the first plan year 
for which the new method is used.
    Example (7). The facts are the same as in Example (6). However, the 
actuary proposes to allocate all the assets to employee M, the older 
employee. Method F, under these facts, is not an acceptable funding 
method because the allocation is not in proportion to related 
liabilities as required under paragraph (c)(5) of this section.
