                       TITLE 26--INTERNAL REVENUE
 
    CHAPTER I--INTERNAL REVENUE SERVICE, DEPARTMENT OF THE TREASURY 
                               (CONTINUED)
 
PART 1_INCOME TAXES--Table of Contents
 
Sec. 1.404(a)-14  Special rules in connection with the Employee 
Retirement Income Security Act of 1974.

    (a) Purpose of this section. This section provides rules for 
determining the deductible limit under section 404(a)(1)(A) of the 
Internal Revenue Code of 1954 for defined benefit plans.
    (b) Definitions. For purposes of this section--
    (1) Section 404(a). The term ``old section 404(a)'' means section 
404(a) as in effect on September 1, 1974. Any reference to section 404 
without the designation ``old'' is a reference to section 404 as amended 
by the Employee Retirement Income Security Act of 1974.
    (2) Ten-year amortization base. The term ``10-year amortization 
base'' means either the past service and other supplementary pension and 
annuity credits described in section 404(a)(1)(A)(iii) or any base 
established in accordance with paragraph (g) of this section. A plan may 
have several 10-year amortization bases to reflect

[[Page 452]]

different plan amendments, changes in actuarial assumptions, changes in 
funding method, and experience gains and losses of previous years.
    (3) Limit adjustment. The term ``limit adjustment'' with respect to 
any 10-year amortization base is the lesser of--
    (i) The level annual amount necessary to amortize the base over 10 
years using the valuation rate, or
    (ii) The unamortized balance of the base,

in each case using absolute values (solely for the purpose of 
determining which is the lesser). To compute the level amortization 
amount, the base may be divided by the present value of an annuity of 
one dollar, obtained from standard annuity tables on the basis of a 
given interest rate (the valuation rate) and a known period (the 
amortization period).
    (4) Absolute value. The term ``absolute value'' for any number is 
the value of that number, treating negative numbers as if they were 
positive numbers. For example, the absolute value of 5 is 5 and the 
absolute value of minus 3 is 3. On the other hand, the true value of 
minus 3 is minus 3. This term is relevant to the computation of the 
limit adjustment described in paragraph (b)(3) and the remaining 
amortization period of combined bases described in paragraph (i)(3) of 
this section.
    (5) Valuation rate. The term ``valuation rate'' means the assumed 
interest rate used to value plan liabilities.
    (c) Use of plan in determining deductible limit for employer's 
taxable year. Although the deductible limit applies for an employer's 
taxable year, the deductible limit is determined on the basis of a plan 
year. If the employer's taxable year coincides with the plan year, the 
deductible limit for the taxable year is the deductible limit for the 
plan year that coincides with that year. If the employer's taxable year 
does not coincide with the plan year, the deductible limit under section 
404(a)(1)(A) (i), (ii), or (iii) for a given taxable year of the 
employer is one of the following alternatives:
    (1) The deductible limit determined for the plan year commencing 
within the taxable year.
    (2) The deductible limit determined for the plan year ending within 
the taxable year, or
    (3) A weighted average of alternatives (1) and (2). Such an average 
may be based, for example, upon the number of months of each plan year 
falling within the taxable year.

The employer must use the same alternative for each taxable year unless 
consent to change is obtained from the Commissioner under section 446 
(e).
    (d) Computation of deductible limit for a plan year--(1) General 
rules. The computation of the deductible limit for a plan year is based 
on the funding methods, actuarial assumptions, and benefit structure 
used for purposes of section 412, determined without regard to section 
412(g) (relating to the alternative minimum funding standard), for the 
plan year. The method of valuing assets for purposes of section 404 must 
be the same method of valuing assets used for purposes of section 412.
    (2) Special adjustments of computations under section 412. To apply 
the rules of this section (i.e., rules regarding the computation of 
normal cost with aggregate type funding methods, unfunded liabilities, 
and the full funding limitation described in paragraph (k) of the 
section, where applicable) with respect to a given plan year in 
computing deductible limits under section 404 (a)(1)(A), the following 
adjustments must be made:
    (i) There must be excluded from the total assets of the plan the 
amount of any plan contribution for a plan year for which the plan was 
qualified under section 401(a), 403(a) or 405(a) that has not been 
previously deducted, even though that amount may have been credited to 
the funding standard account under section 412(b)(3). In the case of a 
plan using a spread gain funding method which maintains an unfunded 
liability (e.g., the frozen initial liability method, but not the 
aggregate method), the amount described in the preceding sentence must 
be included in the unfunded liability of the plan.
    (ii) There must be included in the total assets of the plan for a 
plan year the amount of any plan contribution that has been deducted 
with respect to a prior plan year, even though that amount is considered 
under section 412

[[Page 453]]

to be contributed in a plan year subsequent to that prior plan year. In 
the case of a plan using a spread gain funding method which does not 
maintain an unfunded liability, the amount described in the preceding 
sentence must be excluded from the unfunded liability of the plan.

The special adjustments described in paragraph (d)(2) (i) and (ii) of 
this section apply on a year-by-year basis for purposes of section 
404(a)(1)(A) only. Thus, the adjustments have no effect on the 
computation of the minimum funding requirement under section 412.
    (e) Special computation rules under section 404(a)(1)(A)(i)--(1) In 
general. For purposes of determining the deductible limit under section 
404(a)(1)(A)(i), the deductible limit with respect to a plan year is the 
sum of--
    (i) The amount required to satisfy the minimum funding standard of 
section 412(a) (determined without regard to section 412(g)) for the 
plan year and
    (ii) An amount equal to the includible employer contributions. The 
term ``includible employer contributions'' means employer contributions 
which were required by section 412 for the plan year immediately 
preceding such plan year, and which were not deductible under section 
404(a) for the prior taxable year of the employer solely because they 
were not contributed during the prior taxable year (determine with 
regard to section 404(a)(6)).
    (2) Rule for an employer using alternative minimum funding standard 
account and computing its deduction under section 404(a)(1)(A)(i). This 
paragraph (e)(2) applies if the minimum funding requirements for the 
plan are determined under the alternative minimum funding standard 
described in section 412(g) for both the current plan year and the 
immediately preceding plan year. In that case, the deductible limit 
under section 404(a)(1)(A)(i) (regarding the minimum funding requirement 
of section 412) for the current year is the sum of the amount determined 
under the rules of paragraph (e)(1) of this section.
    (i) Plus the charge under section 412(b)(2)(D), and
    (ii) Less the credit under section 412(b)(3)(D),

that would be required if in the current plan year the use of the 
alternative method were discontinued.
    (f) Special computation rules under section 404(a)(1)(A) (ii) and 
(iii)--(1) In general. Subject to the full funding limitation described 
in paragraph (k) of this section, the deductible limit under section 
404(a)(1)(A)(ii) and (iii) is the normal cost of the plan (determined in 
accordance with paragraph (d) of this section).
    (2) Adjustments in calculating limit under section 404 
(a)(1)(A)(iii). In calculating the deductible limit under section 
404(a)(1)(A)(iii), the normal cost of the plan is--
    (i) Decreased by the limit adjustments to any unamortized bases 
required by paragraph (g) of this section, for example, bases that are 
due to a net experience gain, a change in actuarial assumptions, a 
change in funding method, or a plan provision or amendment which 
decreases the accrued liability of the plan, and
    (ii) Increased by the limit adjustments of any unamortized 10-year 
amortization bases required by paragraph (g) or (j) of this section, for 
example, bases that are due to a net experience loss, a change in 
actuarial assumptions, a change in funding method, or a plan provision 
or amendment which increases the accrued liability.
    (3) Timing for computations and interest adjustments under section 
404(a)(1)(A) (ii) and (iii). Regardless of the actual time when 
contributions are made to a plan, in computing the deductible limit 
under section 404(a)(1)(A) (ii) and (iii) the normal cost and limit 
adjustments shall be computed as of the date when contributions are 
assumed to be made (``the computation date'') and adjusted for interest 
at the valuation rate from the computation date to the earlier of--
    (i) The last day of the plan year used to compute the deductible 
limit for the taxable year, or
    (ii) The last day of that taxable year. For additional provisions 
relating to the timing of computations and interest adjustments, see 
paragraph (h)(6) of this section (relating to the timing of computations 
and interest adjustments

[[Page 454]]

in the maintenance of 10-year amortization bases). For taxable years 
beginning before April 22, 1981, computations under the preceding 
sentence may, as an alternative, be based on prior published positions 
of the Internal Revenue Service under section 404(a).
    (4) Special limit under section 404(a)(1)(A)(ii). If the deduction 
for the plan year is determined solely on the basis of section 
404(a)(1)(A)(ii) (that is, without regard to clauses (i) or (iii)), the 
special limitation contained in section 404(a)(1)(A)(ii), regarding the 
unfunded cost with respect to any three individuals, applies, 
notwithstanding the rules contained in paragraphs (d)(2) and (f)(1) of 
this section.
    (g) Establishment of a 10-year amortization base--(1) Experience 
gains and losses. In the case of a plan valued by the use of a funding 
method which is an immediate gain type of funding method (and therefore 
separately amortizes rather than includes experience gains and losses as 
a part of the normal cost of the plan), a 10-year amortization base must 
be established in any plan year equal to the net experience gain or loss 
required under section 412 to be determined with respect to that plan 
year. The base is to be maintained in accordance with paragraph (h) of 
this section. Such a base must not be established if the deductible 
limit is determined by use of a funding method which is a spread gain 
type of funding method (under which experience gains and losses are 
spread over future periods as a part of the plan's normal cost). 
Examples of the immediate gain type of funding method are the unit 
credit method, entry age normal cost method, and the individual level 
premium cost method. Examples of the spread gain type of funding method 
are the aggregate cost method, frozen initial liability cost method, and 
the attained age normal cost method.
    (2) Change in actuarial assumptions. (i) If the creation of an 
amortization base is required under the rules of section 412(b) 
(2)(B)(v) or (3)(B)(iii) (as applied to the funding method used by the 
plan), a 10-year amortization base must be established at the time of a 
change in actuarial assumptions used to value plan liabilities. The 
amount of the base is the difference between the accrued liability 
calculated on the basis of the new assumptions and the accrued liability 
calculated on the basis of the old assumptions. Both computations of 
accrued liability are made as of the date of the change in assumptions.
    (ii) A plan using a funding method of the spread gain type does not 
directly determine an accrued liability. If a plan using such a method 
is required under section 412(b) (2)(B)(v) or (3)(B)(iii) to create an 
amortization base, it must establish a base as described in paragraph 
(g)(2)(i) of this section for a change in actuarial assumptions by 
determining an accrued liability on the basis of another funding method 
(of the immediate gain type) that does determine an accrued liability. 
(The aggregate method is an example of a funding method that is not 
required under section 412(b) (2)(B)(v) or (3)(B)(iii) to create an 
amortization base.) The funding method chosen to determine the accrued 
liability of the plan in these cases must be the same method used to 
establish all other 10-year amortization bases maintained by the plan, 
if any. These bases must be maintained in accordance with paragraph (h) 
of this section.
    (3) Past service or supplemental credits. A 10-year base must be 
established when a plan is established or amended, if the creation of an 
amortizable base is required under the rules of section 412(b)(2)(B) 
(ii) or (iii), or (b)(3)(B)(i) (as applied to the funding method used by 
the plan). The amount of the base is the accrued liability arising from, 
or the decrease in accrued liability resulting from, the establishment 
or amendment of the plan. The base must be maintained in accordance with 
paragraph (h) of this section.
    (4) Change in funding method. If a change in funding method results 
in an increase or decrease in an unfunded liability required to be 
amortized under section 412, a 10-year base must be established equal to 
the increase or decrease in unfunded liability resulting from the change 
in funding method. The base must be maintained in accordance with 
paragraph (h) of this section.
    (h) Maintenance of 10-year amortization base--(1) In general. Each 
time a 10-year amortization base is established,

[[Page 455]]

whether by a change in funding method, by plan amendment, by change in 
actuarial assumptions, or by experience gains and losses, the base must, 
except as provided in paragraph (i) of this section, be separately 
maintained in order to determine when the unamortized amount of the base 
is zero. The sum of the unamortized balances of all of the 10-year bases 
must equal the plan's unfunded liability with the adjustments described 
in paragraph (d) of this section, if applicable. When the unamortized 
amount of a base is zero, the deductible limit is no longer adjusted to 
reflect the amortization of the base.
    (2) First year's base. See either paragraph (g) or paragraph (i) of 
this section for rules applicable with respect to the first year of a 
base.
    (3) Succeeding year's base. For any plan year after the first year 
of a base, the unamortized amount of the base is equal to--
    (i) The unamortized amount of the base as of the valuation date in 
the prior plan year, plus
    (ii) Interest at the valuation rate from the valuation date in the 
prior plan year to the valuation date in the current plan year on the 
amount described in subdivision (i), minus
    (iii) The contribution described in paragraph (h)(4) of this section 
with respect to the base for the prior plan year.

The valuation date is the date as of which plan liabilities are valued 
under section 412(c)(9). If such a valuation is performed less often 
than annually for purposes of section 412, bases must be adjusted for 
purposes of section 404 each year as of the date on which a section 412 
valuation would be performed were it required on an annual basis. See 
paragraph (b)(3) of this section for the definition of valuation rate.
    (4) Contribution allocation with respect to each base. A portion of 
the total contribution for the prior plan year is allocated to each 
base. Generally, this portion equals the product of--
    (i) The total contribution described in paragraph (h)(6) of this 
section with respect to all bases, and
    (ii) The ratio of the amount described in paragraph (b)(3)(i) of 
this section with respect to the base to the sum (using true rather than 
absolute values) of such amounts with respect to all remaining bases.

However, if the result of this computation with respect to a particular 
base exceeds the amount necessary to amortize such base fully, the 
smaller amount shall be deemed the contribution made with respect to 
such base. The unallocated excess with respect to a now fully amortized 
base shall be allocated among the other bases as indicated above.
    (5) Other allocation methods. The Commissioner may authorize the use 
of methods other than the method described in paragraph (h)(4) of this 
section for allocating contributions to bases.
    (6) Total contribution for all bases. The contribution with respect 
to all bases for the prior plan year (see paragraph (h)(3)(iii) of this 
section) is the difference between--
    (i) The sum of (A) the total deduction (including a carryover 
deduction) for the prior year, (B) interest on the actual contributions 
for the prior year (whether or not deductible) at the valuation rate for 
the period between the dates as of which the contributions are credited 
under section 412 and the valuation date in the current plan year, and 
(C) interest on the carryover described in section 404(a)(1)(D) that is 
available at the beginning of the prior taxable year at the valuation 
rate for the period between the current and prior valuation dates, and
    (ii) The normal cost for the prior plan year and interest on it at 
the valuation rate from the date as of which the normal cost is 
calculated to the current valuation date.
    (7) Effect of failure to contribute normal cost plus interest on 
unamortized amounts. The failure to make a contribution at least equal 
to the sum of the normal cost plus interest on the unamortized amounts 
has the following effects under the preceding rules of this section--
    (i) It does not create a new base.
    (ii) It results in an increase in the unamortized amount of each 
base and consequently extends the time before the base is fully 
amortized.
    (iii) The limit adjustment for any base is not increased (in 
absolute

[[Page 456]]

terms) even if the unamortized amount computed under paragraph (h) of 
this section exceeds the initial 10-year amortization base. Thus, if the 
total unamortized amount of the plan's bases at the beginning of the 
plan year is $100,000 (which is also the unfunded liability of the 
plan), and a required $50,000 normal cost contribution is not made for 
the plan year, the following effects occur. The total unamortized 
balance of the plan's bases increases by the $50,000 normal cost for the 
year (adjusted for interest), plus interest on the $100,000 balance of 
the bases; and, because of that increase, it will take a longer period 
to amortize the remaining balance of the bases. (The annual amortization 
amount does not change.)
    (8) Required adjustment to a 10-year base limit adjustment if 
valuation rate changed. If there is a change in the valuation rate, the 
limit adjustment for all unamortized 10-year amortization bases must be 
changed, in addition to establishing a new base as provided in paragraph 
(g)(2) of this section. The new limit adjustment for any base is the 
level amount necessary to amortize the unamortized amount of the base 
over the remaining amortization period using the new valuation rate. The 
remaining amortization period of the base is the number of years at the 
end of which the unamortized amount of the base would be zero if the 
contribution made with respect to that base equaled the limit adjustment 
each year. This calculation of the remaining period is made on the basis 
of the valuation rate used before the change. Both the remaining 
amortization period and the revised limit adjustment may be determined 
through the use of standard annuity tables. The remaining period may be 
computed in terms of fractional years, or it may be rounded off to a 
full year. The unamortized amount of the base as of the valuation date 
and the remaining amortization period of that base shall not be changed 
by any change in the valuation rate.
    (i) Combining bases--(1) General method. For purposes of section 404 
only, and not for purposes of section 412, different 10-year 
amortization bases may be combined into a single 10-year amortization 
base if such single base satisfies all of the requirements of paragraph 
(i) (2), (3), and (4) of this section at the time of the combining of 
the different bases.
    (2) Unamortized amount. The unamortized amount of the single base 
equals the sum, as of the date the combination is made, of the 
unamortized amount of the bases being combined (treating negative bases 
as having negative unamortized amounts).
    (3) Remaining amortization period. The remaining amortization period 
of the single base is equal to (i) the sum of the separate products of 
(A) the unamortized amount of each of these bases (using absolute 
values) and (B) its remaining amortization period, divided by (ii) the 
sum of the unamortized amounts of each of the bases (using absolute 
values). For purposes of this paragraph (i)(3), the remaining 
amortization period of each base being combined is that number of years 
at the end of which the unamortized amount of the base would be zero if 
the contribution made with respect to that base equaled the limit 
adjustment of that base in each year. This number may be determined 
through the use of standard annuity tables. The remaining amortization 
period described in this paragraph may be computed in terms of 
fractional years, or it may be rounded off to a whole year.
    (4) Limit adjustment. The limit adjustment for the single base is 
the level amount necessary to amortize the unamortized amount of the 
combined base over the remaining amortization period described in 
paragraph (i)(3) of this section, using the valuation rate. This amount 
may be determined through the use of standard annuity tables.
    (5) Fresh start alternative. In lieu of combining different 10-year 
amortization bases, a plan may replace all existing bases with one new 
10-year amortization base equal to the unfunded liability of the plan as 
of the time the new base is being established. This unfunded liability 
must be determined in accordance with the general rules of paragraphs 
(d) and (f) of this section. The unamortized amount of the base and the 
limit adjustment for the base will be determined as though the base were 
newly established.

[[Page 457]]

    (j) Initial 10-year amortization base for existing plan--(1) In 
general. In the case of a plan in existence before the effective date of 
section 404(a), the 10-year amortization base on the effective date of 
section 404(a) is the sum of all 10 percent bases existing immediately 
before section 404(a) became effective for the plan, determined under 
the rules of old section 404(a).
    (2) Limit adjustment. The limit adjustment for the initial base is 
the lesser of the unamortized amount of such base or the sum of the 
amounts determined under paragraph (b)(3) of this section using the 
original balances of the remaining bases (under old section 404(a) 
rules) as the amount to be amortized.
    (3) Unamortized amount. The employer may choose either to establish 
a single initial base reflecting both all prior 10-percent bases and the 
experience gain or loss for the immediately preceding actuarial period, 
or to establish a separate base for the prior 10-percent bases and 
another for the experience gain or loss for the immediately preceding 
period. If the initial 10-year amortization base reflects the net 
experience gain or loss from the immediately preceding actuarial period, 
the unamortized amount of the initial base shall equal the total 
unfunded liability on the effective date of section 404(a) determined in 
accordance with the general rules of paragraphs (d) and (f) of this 
section. If, however, a separate base will be used to reflect that gain 
or loss, the unamortized amount of the initial base shall equal such 
unfunded liability on the effective date of section 404(a), reduced by 
the net experience loss or increased by the net experience gain for the 
immediately preceding actuarial period. In this case, a separate 10-year 
amortization base must be established on the effective date equal to the 
net experience gain or loss. Thus, if the effective date unfunded 
liability is $100,000 and an experience loss of $15,000 is recognized on 
that date, and if the loss is to be treated as a separate base, the 
unamortized balances of the two bases would be $85,000 and $15,000. If 
the unfunded liability were the same $100,000, but a gain of $15,000 
instead of a loss were recognized on that date, the unamortized balances 
of the two bases would be $115,000 and a credit base of $15,000. In both 
cases, if only one 10-year base is to be established on the effective 
date, its unamortized balance would be $100,000 (the unfunded liability 
of the plan). See paragraphs (d) and (f) for rules for determining the 
unfunded liability of the plan.
    (k) Effect of full funding limit on 10-year-amortization bases. The 
amount deductible under section 404(a)(1)(A) (i), (ii), or (iii) for a 
plan year may not exceed the full funding limitation for that year. See 
section 412 and paragraphs (d), (e), and (f) of this section for rules 
to be used in the computation of the full funding limitation. If the 
total deductible contribution (including carryover) for a plan year 
equals or exceeds the full funding limitation for the year, all 10-year 
amortization bases maintained by the plan will be considered fully 
amortized, and the deductible limit for subsequent plan years will not 
be adjusted to reflect the amortization of these bases.
    (l) Transitional rules--(1) Plan years beginning before April 22, 
1981. In determining the deductible limit for plan years beginning 
before April 22, 1981, a contribution will be deductible under section 
404(a)(1)(A) if the computation of the deductible limit is based on an 
interpretation of section 404(a)(1)(A) that is reasonable when 
considered with prior published positions of the Internal Revenue 
Service. A computation of the deductible limit may satisfy the preceding 
sentence even if it does not satisfy the rules contained in paragraphs 
(c) through (i) of this section.
    (2) Transitional approaches. The deductible limit determined for the 
first plan year with respect to which a plan applies the rules contained 
in paragraphs (c) through (i) of this section must be computed using one 
of the following approaches--
    (i) The plan (whether or not in existence before the effective date 
of section 404(a)) may apply the rules of paragraph (j) for establishing 
the initial base for an existing plan, treating 10-year bases (if any) 
as 10 percent bases in adding bases.
    (ii) The plan may apply the fresh start alternative for combining 
bases under paragraph (i)(5).
    (iii) The plan may retroactively establish 10-year amortization 
bases for

[[Page 458]]

years with respect to which section 404(a)(1)(A) and the rules of this 
section would have applied but for the transition rule contained in 
paragraph (l)(1) of this section. Contributions actually deducted are 
used in retroactively establishing and maintaining these bases under 
paragraph (h). However, a deduction already taken shall not be 
recomputed because of the retroactive establishment of a base.
    (m) Effective date of section 404(a). In the case of a plan which 
was in existence on January 1, 1974, section 404(a) generally applies 
for contributions on account of taxable years of an employer ending with 
or within plan years beginning after December 31, 1974. In the case of a 
plan not in existence on January 1, 1974, section 404(a) generally 
applies for contributions on account of taxable years of an employer 
ending with or within plan years beginning after September 4, 1974. See 
Sec. 1.410(a)-2(c) for rules concerning the time of plan existence. See 
also Sec. 1.410(a)-2(d), which provides that a plan in existence on 
January 1, 1974, may elect to have certain provisions, including the 
amendments to section 404(a) contained in section 1013 of the Employee 
Retirement Income Security Act of 1974, apply to a plan year beginning 
after September 2, 1974, and before the otherwise applicable effective 
date contained in that section.
