Sec. 1.401(k)-2  ADP test.

    (a) Actual deferral percentage (ADP) test--(1) In general--(i) ADP 
test formula. A cash or deferred arrangement satisfies the ADP test for 
a plan year only if--
    (A) The ADP for the eligible HCEs for the plan year is not more than 
the ADP for the eligible NHCEs for the applicable year multiplied by 
1.25; or
    (B) The excess of the ADP for the eligible HCEs for the plan year 
over the ADP for the eligible NHCEs for the applicable year is not more 
than 2 percentage points, and the ADP for the eligible HCEs for the plan 
year is not more than the ADP for the eligible NHCEs for the applicable 
year multiplied by 2.
    (ii) HCEs as sole eligible employees. If, for the applicable year 
for determining the ADP of the NHCEs for a plan year, there are no 
eligible NHCEs (i.e., all of the eligible employees under the cash or 
deferred arrangement for the applicable year are HCEs), the arrangement 
is deemed to satisfy the ADP test for the plan year.
    (iii) Special rule for early participation. If a cash or deferred 
arrangement provides that employees are eligible to participate before 
they have completed the minimum age and service requirements of section 
410(a)(1)(A), and if the plan applies section 410(b)(4)(B) in 
determining whether the cash or deferred arrangement meets the 
requirements of section 410(b)(1), then in determining whether the 
arrangement meets the requirements under paragraph (a)(1) of this 
section, either--
    (A) Pursuant to section 401(k)(3)(F), the ADP test is performed 
under the plan (determined without regard to disaggregation under Sec. 
1.410(b)-7(c)(3)), using the ADP for all eligible HCEs for the plan year 
and the ADP of eligible NHCEs for the applicable year, disregarding all 
NHCEs who have not met the minimum age and service requirements of 
section 410(a)(1)(A); or
    (B) Pursuant to Sec. 1.401(k)-1(b)(4), the plan is disaggregated 
into separate plans and the ADP test is performed separately for all 
eligible employees who have completed the minimum age and service 
requirements of section 410(a)(1)(A) and for all eligible employees who 
have not completed the minimum age and service requirements of section 
410(a)(1)(A).
    (2) Determination of ADP--(i) General rule. The ADP for a group of 
eligible employees (either eligible HCEs or eligible NHCEs) for a plan 
year or applicable year is the average of the ADRs of the eligible 
employees in that group for that year. The ADP for a group of eligible 
employees is calculated to the nearest hundredth of a percentage point.
    (ii) Determination of applicable year under current year and prior 
year testing method. The ADP test is applied using the prior year 
testing method or the current year testing method. Under the prior year 
testing method, the applicable year for determining the ADP for the 
eligible NHCEs is the plan year immediately preceding the plan year for 
which the ADP test is being performed. Under the prior year testing 
method, the ADP for the eligible NHCEs is determined using the ADRs for 
the eligible employees who were NHCEs in that

[[Page 321]]

preceding plan year, regardless of whether those NHCEs are eligible 
employees or NHCEs in the plan year for which the ADP test is being 
calculated. Under the current year testing method, the applicable year 
for determining the ADP for the eligible NHCEs is the same plan year as 
the plan year for which the ADP test is being performed. Under either 
method, the ADP for eligible HCEs is the average of the ADRs of the 
eligible HCEs for the plan year for which the ADP test is being 
performed. See paragraph (c) of this section for additional rules for 
the prior year testing method.
    (3) Determination of ADR--(i) General rule. The ADR of an eligible 
employee for a plan year or applicable year is the sum of the employee's 
elective contributions taken into account with respect to such employee 
for the year, determined under the rules of paragraphs (a)(4) and (5) of 
this section, and the qualified nonelective contributions and qualified 
matching contributions taken into account with respect to such employee 
under paragraph (a)(6) of this section for the year, divided by the 
employee's compensation taken into account for the year. The ADR is 
calculated to the nearest hundredth of a percentage point. If no 
elective contributions, qualified nonelective contributions, or 
qualified matching contributions are taken into account under this 
section with respect to an eligible employee for the year, the ADR of 
the employee is zero.
    (ii) ADR of HCEs eligible under more than one arrangement--(A) 
General rule. Pursuant to section 401(k)(3)(A), the ADR of an HCE who is 
an eligible employee in more than one cash or deferred arrangement of 
the same employer is calculated by treating all contributions with 
respect to such HCE under any such arrangement as being made under the 
cash or deferred arrangement being tested. Thus, the ADR for such an HCE 
is calculated by accumulating all contributions under any cash or 
deferred arrangement (other than a cash or deferred arrangement 
described in paragraph (a)(3)(ii)(B) of this section) that would be 
taken into account under this section for the plan year, if the cash or 
deferred arrangement under which the contribution was made applied this 
section and had the same plan year. For example, in the case of a plan 
with a 12-month plan year, the ADR for the plan year of that plan for an 
HCE who participates in multiple cash or deferred arrangements of the 
same employer is the sum of all contributions during such 12-month 
period that would be taken into account with respect to the HCE under 
all such arrangements in which the HCE is an eligible employee, divided 
by the HCE's compensation for that 12-month period (determined using the 
compensation definition for the plan being tested), without regard to 
the plan year of the other plans and whether those plans are satisfying 
this section or Sec. 1.401(k)-3.
    (B) Plans not permitted to be aggregated. Cash or deferred 
arrangements under plans that are not permitted to be aggregated under 
Sec. 1.401(k)-1(b)(4) (determined without regard to the prohibition on 
aggregating plans with inconsistent testing methods set forth in Sec. 
1.401(k)-1(b)(4)(iii)(B) and the prohibition on aggregating plans with 
different plan years set forth in Sec. 1.410(b)-7(d)(5)) are not 
aggregated under this paragraph (a)(3)(ii).
    (iii) Examples. The following examples illustrate the application of 
this paragraph (a)(3):

    Example 1. (i) Employee A, an HCE with compensation of $120,000, is 
eligible to make elective contributions under Plan S and Plan T, two 
profit-sharing plans maintained by Employer H with calendar year plan 
years, each of which includes a cash or deferred arrangement. During the 
current plan year, Employee A makes elective contributions of $6,000 to 
Plan S and $4,000 to Plan T.
    (ii) Under each plan, the ADR for Employee A is determined by 
dividing Employee A's total elective contributions under both 
arrangements by Employee A's compensation taken into account under the 
plan for the year. Therefore, Employee A's ADR under each plan is 8.33% 
($10,000/$120,000).
    Example 2. (i) The facts are the same as in Example 1, except that 
Plan T defines compensation (for deferral and testing purposes) to 
exclude all bonuses paid to an employee. Plan S defines compensation 
(for deferral and testing purposes) to include bonuses paid to an 
employee. During the current year, Employee A's compensation included a 
$10,000 bonus. Therefore, Employee A's compensation under Plan T is 
$110,000 and Employee A's compensation under Plan S is $120,000.

[[Page 322]]

    (ii) Employee A's ADR under Plan T is 9.09% ($10,000/$110,000) and 
under Plan S, Employee A's ADR is 8.33% ($10,000/$120,000).
    Example 3. (i) Employer J sponsors two profit-sharing plans, Plan U 
and Plan V, each of which includes a cash or deferred arrangement. Plan 
U's plan year begins on July 1 and ends on June 30. Plan V has a 
calendar year plan year. Compensation under both plans is limited to the 
participant's compensation during the period of participation. Employee 
B is an HCE who participates in both plans. Employee B's monthly 
compensation and elective contributions to each plan for the 2005 and 
2006 calendar years are as follows:

------------------------------------------------------------------------
                                                 Monthly       Monthly
                                   Monthly      elective      elective
         Calendar year          compensation  contribution  contribution
                                                to Plan U     to Plan V
------------------------------------------------------------------------
2005..........................      $10,000          $500          $400
2006..........................       11,500           700           550
------------------------------------------------------------------------

    (ii) Under Plan U, Employee B's ADR for the plan year ended June 30, 
2006, is equal to Employee B's total elective contributions under Plan U 
and Plan V for the plan year ending June 30, 2006, divided by Employee 
B's compensation for that period. Therefore, Employee B's ADR under Plan 
U for the plan year ending June 30, 2006, is (($900 x 6) + ($1,250 x 6)) 
/ (($10,000 x 6) + ($11,500 x 6)), or 10%.
    (iii) Under Plan V, Employee B's ADR for the plan year ended 
December 31, 2005, is equal to total elective contributions under Plan U 
and V for the plan year ending December 31, 2005, divided by Employee 
B's compensation for that period. Therefore, Employee B's ADR under Plan 
V for the plan year ending December 31, 2005, is ($10,800/$120,000), or 
9%.
    Example 4. (i) The facts are the same as Example 3, except that 
Employee B first becomes eligible to participate in Plan U on January 1, 
2006.
    (ii) Under Plan U, Employee B's ADR for the plan year ended June 30, 
2006, is equal to Employee B's total elective contributions under Plan U 
and V for the plan year ending June 30, 2006, divided by Employee B's 
compensation for that period. Therefore, Employee B's ADR under Plan U 
for the plan year ending June 30, 2006, is (($400 x 6) + ($1,250 x 6)) / 
(($10,000 x 6) + ($11,500 x 6)), or 7.67%.

    (4) Elective contributions taken into account under the ADP test--
(i) General rule. An elective contribution is taken into account in 
determining the ADR for an eligible employee for a plan year or 
applicable year only if each of the following requirements is 
satisfied--
    (A) The elective contribution is allocated to the eligible 
employee's account under the plan as of a date within that year. For 
purposes of this rule, an elective contribution is considered allocated 
as of a date within a year only if--
    (1) The allocation is not contingent on the employee's participation 
in the plan or performance of services on any date subsequent to that 
date; and
    (2) The elective contribution is actually paid to the trust no later 
than the end of the 12-month period immediately following the year to 
which the contribution relates.
    (B) The elective contribution relates to compensation that either--
    (1) Would have been received by the employee in the year but for the 
employee's election to defer under the arrangement; or
    (2) Is attributable to services performed by the employee in the 
year and, but for the employee's election to defer, would have been 
received by the employee within 2\1/2\ months after the close of the 
year, but only if the plan provides for elective contributions that 
relate to compensation that would have been received after the close of 
a year to be allocated to such prior year rather than the year in which 
the compensation would have been received.
    (ii) Elective contributions for partners and self-employed 
individuals. For purposes of this paragraph (a)(4), a partner's 
distributive share of partnership income is treated as received on the 
last day of the partnership taxable year and a sole proprietor's 
compensation is treated as received on the last day of the individual's 
taxable year. Thus, an elective contribution made on behalf of a partner 
or sole proprietor is treated as allocated to the partner's account for 
the plan year that includes the last day of the partnership taxable 
year, provided the requirements of paragraph (a)(4)(i) of this section 
are met.
    (iii) Elective contributions for HCEs. Elective contributions of an 
HCE must include any excess deferrals, as described in Sec. 1.402(g)-
1(a), even if those excess deferrals are distributed, pursuant to Sec. 
1.402(g)-1(e).
    (5) Elective contributions not taken into account under the ADP 
test--(i) General

[[Page 323]]

rule. Elective contributions that do not satisfy the requirements of 
paragraph (a)(4)(i) of this section may not be taken into account in 
determining the ADR of an eligible employee for the plan year or 
applicable year with respect to which the contributions were made, or 
for any other plan year. Instead, the amount of the elective 
contributions must satisfy the requirements of section 401(a)(4) 
(without regard to the ADP test) for the plan year for which they are 
allocated under the plan as if they were nonelective contributions and 
were the only nonelective contributions for that year. See Sec. Sec. 
1.401(a)(4)-1(b)(2)(ii)(B) and 1.410(b)-7(c)(1).
    (ii) Elective contributions for NHCEs. Elective contributions of an 
NHCE shall not include any excess deferrals, as described in Sec. 
1.402(g)-1(a), to the extent the excess deferrals are prohibited under 
section 401(a)(30). However, to the extent that the excess deferrals are 
not prohibited under section 401(a)(30), they are included in elective 
contributions even if distributed pursuant to Sec. 1.402(g)-1(e).
    (iii) Elective contributions treated as catch-up contributions. 
Elective contributions that are treated as catch-up contributions under 
section 414(v) because they exceed a statutory limit or employer-
provided limit (within the meaning of Sec. 1.414(v)-1(b)(1)) are not 
taken into account under paragraph (a)(4) of this section for the plan 
year for which the contributions were made, or for any other plan year.
    (iv) Elective contributions used to satisfy the ACP test. Except to 
the extent necessary to demonstrate satisfaction of the requirement of 
Sec. 1.401(m)-2(a)(6)(ii), elective contributions taken into account 
for the ACP test under Sec. 1.401(m)-2(a)(6) are not taken into account 
under paragraph (a)(4) of this section.
    (v) Additional elective contributions pursuant to section 414(u). 
Additional elective contributions made pursuant to section 414(u) by 
reason of an eligible employee's qualified military service are not 
taken into account under paragraph (a)(4) of this section for the plan 
year for which the contributions are made, or for any other plan year.
    (6) Qualified nonelective contributions and qualified matching 
contributions that may be taken into account under the ADP test. 
Qualified nonelective contributions and qualified matching contributions 
may be taken into account in determining the ADR for an eligible 
employee for a plan year or applicable year but only to the extent the 
contributions satisfy the following requirements--
    (i) Timing of allocation. The qualified nonelective contribution or 
qualified matching contribution is allocated to the employee's account 
as of a date within that year within the meaning of paragraph 
(a)(4)(i)(A) of this section. Consequently, under the prior year testing 
method, in order to be taken into account in calculating the ADP for the 
eligible NHCEs for the applicable year, a qualified nonelective 
contribution or qualified matching contribution must be contributed no 
later than the end of the 12-month period immediately following the 
applicable year even though the applicable year is different than the 
plan year being tested.
    (ii) Requirement that amount satisfy section 401(a)(4). The amount 
of nonelective contributions, including those qualified nonelective 
contributions taken into account under this paragraph (a)(6) and those 
qualified nonelective contributions taken into account for the ACP test 
of section 401(m)(2) under Sec. 1.401(m)-2(a)(6), satisfies the 
requirements of section 401(a)(4). See Sec. 1.401(a)(4)-1(b)(2). The 
amount of nonelective contributions, excluding those qualified 
nonelective contributions taken into account under this paragraph (a)(6) 
and those qualified nonelective contributions taken into account for the 
ACP test of section 401(m)(2) under Sec. 1.401(m)-2(a)(6), satisfies 
the requirements of section 401(a)(4). See Sec. 1.401(a)(4)-1(b)(2). In 
the case of an employer that is applying the special rule for employer-
wide plans in Sec. 1.414(r)-1(c)(2)(ii) with respect to the cash or 
deferred arrangement, the determination of whether the qualified 
nonelective contributions satisfy the requirements of this paragraph 
(a)(6)(ii) must be made on an employer-wide basis regardless of whether 
the

[[Page 324]]

plans to which the qualified nonelective contributions are made are 
satisfying the requirements of section 410(b) on an employer-wide basis. 
Conversely, in the case of an employer that is treated as operating 
qualified separate lines of business, and does not apply the special 
rule for employer-wide plans in Sec. 1.414(r)-1(c)(2)(ii) with respect 
to the cash or deferred arrangement, then the determination of whether 
the qualified nonelective contributions satisfy the requirements of this 
paragraph (a)(6)(ii) is not permitted to be made on an employer-wide 
basis regardless of whether the plans to which the qualified nonelective 
contributions are made are satisfying the requirements of section 410(b) 
on that basis.
    (iii) Aggregation must be permitted. The plan that contains the cash 
or deferred arrangement and the plan or plans to which the qualified 
nonelective contributions or qualified matching contributions are made, 
are plans that would be permitted to be aggregated under Sec. 1.401(k)-
1(b)(4). If the plan year of the plan that contains the cash or deferred 
arrangement is changed to satisfy the requirement under Sec. 1.410(b)-
7(d)(5) that aggregated plans have the same plan year, qualified 
nonelective contributions and qualified matching contributions may be 
taken into account in the resulting short plan year only if such 
qualified nonelective contributions and qualified matching contributions 
could have been taken into account under an ADP test for a plan with the 
same short plan year.
    (iv) Disproportionate contributions not taken into account--(A) 
General rule. Qualified nonelective contributions cannot be taken into 
account for a plan year for an NHCE to the extent such contributions 
exceed the product of that NHCE's compensation and the greater of 5% or 
two times the plan's representative contribution rate. Any qualified 
nonelective contribution taken into account under an ACP test under 
Sec. 1.401(m)-2(a)(6) (including the determination of the 
representative contribution rate for purposes of Sec. 1.401(m)-
2(a)(6)(v)(B)), is not permitted to be taken into account for purposes 
of this paragraph (a)(6) (including the determination of the 
representative contribution rate under paragraph (a)(6)(iv)(B) of this 
section).
    (B) Definition of representative contribution rate. For purposes of 
this paragraph (a)(6)(iv), the plan's representative contribution rate 
is the lowest applicable contribution rate of any eligible NHCE among a 
group of eligible NHCEs that consists of half of all eligible NHCEs for 
the plan year (or, if greater, the lowest applicable contribution rate 
of any eligible NHCE in the group of all eligible NHCEs for the plan 
year and who is employed by the employer on the last day of the plan 
year).
    (C) Definition of applicable contribution rate. For purposes of this 
paragraph (a)(6)(iv), the applicable contribution rate for an eligible 
NHCE is the sum of the qualified matching contributions taken into 
account under this paragraph (a)(6) for the eligible NHCE for the plan 
year and the qualified nonelective contributions made for the eligible 
NHCE for the plan year, divided by the eligible NHCE's compensation for 
the same period.
    (D) Special rule for prevailing wage contributions. Notwithstanding 
paragraph (a)(6)(iv)(A) of this section, qualified nonelective 
contributions that are made in connection with an employer's obligation 
to pay prevailing wages under the Davis-Bacon Act (46 Stat. 1494), 
Public Law 71-798, Service Contract Act of 1965 (79 Stat. 1965), Public 
Law 89-286, or similar legislation can be taken into account for a plan 
year for an NHCE to the extent such contributions do not exceed 10 
percent of that NHCE's compensation.
    (v) Qualified matching contributions. Qualified matching 
contributions satisfy this paragraph (a)(6) only to the extent that such 
qualified matching contributions are matching contributions that are not 
precluded from being taken into account under the ACP test for the plan 
year under the rules of Sec. 1.401(m)-2(a)(5)(ii).
    (vi) Contributions only used once. Qualified nonelective 
contributions and qualified matching contributions cannot be taken into 
account under this paragraph (a)(6) to the extent such contributions are 
taken into account for purposes of satisfying any other

[[Page 325]]

ADP test, any ACP test, or the requirements of Sec. 1.401(k)-3, 
1.401(m)-3 or 1.401(k)-4. Thus, for example, matching contributions that 
are made pursuant to Sec. 1.401(k)-3(c) cannot be taken into account 
under the ADP test. Similarly, if a plan switches from the current year 
testing method to the prior year testing method pursuant to Sec. 
1.401(k)-2(c), qualified nonelective contributions that are taken into 
account under the current year testing method for a year may not be 
taken into account under the prior year testing method for the next 
year.
    (7) Examples. The following examples illustrate the application of 
this paragraph (a):

    Example 1. (i) Employer X has three employees, A, B, and C. Employer 
X sponsors a profit-sharing plan (Plan Z) that includes a cash or 
deferred arrangement. Each year, Employer X determines a bonus 
attributable to the prior year. Under the cash or deferred arrangement, 
each eligible employee may elect to receive none, all or any part of the 
bonus in cash. X contributes the remainder to Plan Z. The portion of the 
bonus paid in cash, if any, is paid 2 months after the end of the plan 
year and thus is included in compensation for the following plan year. 
Employee A is an HCE, while Employees B and C are NHCEs. The plan uses 
the current year testing method and defines compensation to include 
elective contributions and bonuses paid during each plan year. In 
February of 2005, Employer X determined that no bonuses will be paid for 
2004. In February of 2006, Employer X provided a bonus for each employee 
equal to 10% of regular compensation for 2005. For the 2005 plan year, 
A, B, and C have the following compensation and make the following 
elections:

------------------------------------------------------------------------
                                                             Elective
                Employee                   Compensation    contribution
------------------------------------------------------------------------
A.......................................        $100,000          $4,340
B.......................................          60,000           2,860
C.......................................          45,000           1,250
------------------------------------------------------------------------

    (ii) For each employee, the ratio of elective contributions to the 
employee's compensation for the plan year is:

------------------------------------------------------------------------
                                          Ratio of elective
                Employee                   contribution to       ADR
                                             compensation     (percent)
------------------------------------------------------------------------
A.......................................    $4,340/$100,000         4.34
B.......................................       2,860/60,000         4.77
C.......................................       1,250/45,000         2.78
------------------------------------------------------------------------

    (iii) The ADP for the HCEs (Employee A) is 4.34%. The ADP for the 
NHCEs is 3.78% ((4.77% + 2.78%)/2). Because 4.34% is less than 4.73% 
(3.78% multiplied by 1.25), the plan satisfies the ADP test under 
paragraph (a)(1)(i) of this section.
    Example 2. (i) The facts are the same as in Example 1, except that 
elective contributions are made pursuant to a salary reduction agreement 
throughout the plan year, and no bonuses are paid. As provided by 
section 414(s)(2), Employer X includes elective contributions in 
compensation. During the year, B and C defer the same amount as in 
Example 1, but A defers $5,770. Thus, the compensation and elective 
contributions for A, B, and C are:

----------------------------------------------------------------------------------------------------------------
                                                                                        Elective         ADR
                              Employee                                Compensation    contributions   (percent)
----------------------------------------------------------------------------------------------------------------
A..................................................................        $100,000          $5,770         5.77
B..................................................................          60,000           2,860         4.77
C..................................................................          45,000           1,250         2.78

    (ii) The ADP for the HCEs (Employee A) is 5.77%. The ADP for the 
NHCEs is 3.78% ((4.77% + 2.78%)/2). Because 5.77% exceeds 4.73% (3.78% x 
1.25), the plan does not satisfy the ADP test under paragraph (a)(1)(i) 
of this section. However, because the ADP for the HCEs does not exceed 
the ADP for the NHCEs by more than 2 percentage points and the ADP for 
the HCEs does not exceed the ADP for the NHCEs multiplied by 2 (3.78% x 
2 = 7.56%), the plan satisfies the ADP test under paragraph (a)(1)(ii) 
of this section.
    Example 3. (i) Employees D through L are eligible employees in Plan 
T, a profit-sharing plan that contains a cash or deferred arrangement. 
The plan is a calendar year plan that uses the prior year testing 
method. Plan T provides that elective contributions are included in 
compensation (as provided under section 414(s)(2)). Each eligible 
employee may elect to defer up to 6% of compensation under the cash or 
deferred arrangement. Employees D and E are HCEs. The compensation, 
elective contributions, and ADRs of Employees D and E for the 2006 plan 
year are shown below:

                                                                                     Elective

----------------------------------------------------------------------------------------------------------------

    (ii) During the 2005 plan year, Employees F through L were eligible 
NHCEs. The compensation, elective contributions and ADRs of Employees F 
through L for the 2005 plan year are shown in the following table:

----------------------------------------------------------------------------------------------------------------
                                                                                     Elective
                                                                   Compensation    contributions   ADR for 2005

----------------------------------------------------------------------------------------------------------------

    (iii) The ADP for 2006 for the HCEs is 7.5%. Because Plan T is using 
the prior year testing method, the applicable year for determining the 
NHCE ADP is the prior plan year (i.e., 2005). The NHCE ADP is determined 
using the ADRs for NHCEs eligible during the prior plan year (without 
regard to whether they are eligible under the plan during the plan 
year). The ADP for the NHCEs is 3.71% (the sum of the individual ADRs, 
26%, divided by 7 employees). Because 7.5% exceeds 4.64% (3.71% x 1.25), 
Plan T does not satisfy the ADP test under paragraph (a)(1)(i) of this 
section. In addition, because the ADP for the HCEs exceeds the ADP for 
the NHCEs by more than 2 percentage points, Plan T does not satisfy the 
ADP test under paragraph (a)(1)(ii) of this section. Therefore, the cash 
or deferred arrangement fails to be a qualified cash or deferred 
arrangement unless the ADP failure is corrected under paragraph (b) of 
this section.
    Example 4. (i) Plan U is a calendar year profit-sharing plan that 
contains a cash or deferred arrangement and uses the current year 
testing method. Plan U provides that elective contributions are included 
in compensation (as provided under section 414(s)(2)). The following 
amounts are contributed under Plan U for the 2006 plan year: QNECs equal 
to 2% of each employee's compensation; Contributions equal to 6% of each 
employee's compensation that are not immediately vested under the terms 
of the plan; 3% of each employee's compensation that the employee may 
elect to receive as cash or to defer under the plan. Both types of 
nonelective contributions are made for the HCEs (employees M and N) and 
the NHCEs (employees O through S) for the plan year and are contributed 
after the end of the plan year and before the end of the following plan 
year. In addition, neither type of nonelective contributions is used for 
any other ADP or ACP test.
    (ii) For the 2006 plan year, the compensation, elective 
contributions, and actual deferral ratios of employees M through S are 
shown in the following table:

----------------------------------------------------------------------------------------------------------------
                                                                                                      Actual
                            Employee                               Compensation      Elective     deferral ratio
                                                                                   contributions     (percent)
----------------------------------------------------------------------------------------------------------------
M...............................................................        $100,000          $3,000               3
N...............................................................         100,000           2,000               2
O...............................................................          60,000           1,800               3
P...............................................................          40,000               0               0
Q...............................................................          30,000               0               0
R...............................................................           5,000               0               0
S...............................................................          20,000               0               0
----------------------------------------------------------------------------------------------------------------

    (iii) The elective contributions alone do not satisfy the ADP test 
of section 401(k)(3) and paragraph (a)(1) of this section because the 
ADP for the HCEs, consisting of employees M and N, is 2.5% and the ADP 
for the NHCEs is 0.6%.
    (iv) The 2% QNECs satisfies the timing requirement of paragraph 
(a)(6)(i) of this section because it is paid within 12-month after the 
plan year for which allocated. All nonelective contributions also 
satisfy the requirements relating to section 401(a)(4) set forth in 
paragraph (a)(6)(ii) of this section (because all employees receive an 
8% nonelective contribution and the nonelective contributions excluding 
the QNECs is 6% for all employees). In addition, the QNECs are not 
disproportionate under paragraph (a)(6)(iv) of this section because no 
QNEC for an NHCE exceeds the product of the plan's applicable 
contribution rate (2%) and that NHCE's compensation.
    (v) Because the rules of paragraph (a)(6) of this section are 
satisfied, the 2% QNECs may be taken into account in applying the ADP 
test of section 401(k)(3) and paragraph (a)(1) of this section. The 6% 
nonelective contributions, however, may not be taken into account 
because they are not QNECs.
    (vi) If the 2% QNECs are taken into account, the ADP for the HCEs is 
4.5%, and the actual deferral percentage for the NHCEs is 2.6%. Because 
4.5% is not more than two percentage points greater than 2.6 percent, 
and not more than two times 2.6, the cash or deferred arrangement 
satisfies the ADP test of section 401(k)(3) under paragraph (a)(1)(ii) 
of this section.
    Example 5. (i) The facts are the same as Example 4, except the plan 
uses the prior year testing method. In addition, the NHCE ADP for the 
2005 plan year (the prior plan year) is 0.8% and no QNECs are 
contributed for the 2005 plan year during 2005 or 2006.
    (ii) In 2007, it is determined that the elective contributions alone 
do not satisfy the ADP test of section 401(k)(3) and paragraph (a)(1) of 
this section for 2006 because the 2006 ADP for the eligible HCEs, 
consisting of employees M and N, is 2.5% and the 2005 ADP for the 
eligible NHCEs is 0.8%. An additional QNEC of 2% of compensation is made 
for each eligible NHCE in 2007 and allocated for 2005.
    (iii) The 2% QNECs that are made in 2007 and allocated for the 2005 
plan year do not satisfy the timing requirement of paragraph (a)(6)(i) 
of this section for the applicable year for the 2005 plan year because 
they were not contributed before the last day of the 2006 plan year. 
Accordingly, the 2% QNECs do not satisfy the rules of paragraph (a)(6) 
of this section and may not be taken into account in applying the ADP 
test of section 401(k)(3) and paragraph (a)(1) of this section for the 
2006 plan year. The cash or deferred arrangement fails to be a qualified 
cash or

[[Page 327]]

deferred arrangement unless the ADP failure is corrected under paragraph 
(b) of this section.
    Example 6. (i) The facts are the same as Example 4, except that the 
ADP for the HCEs is 4.6% and there is no 6% nonelective contribution 
under the plan. The employer would like to take into account the 2% QNEC 
in determining the ADP for the NHCEs but not in determining the ADP for 
the HCEs.
    (ii) The elective contributions alone fail the requirements of 
section 401(k) and paragraph (a)(1) of this section because the HCE ADP 
for the plan year (4.6%) exceeds 0.75% (0.6% x 1.25) and 1.2% (0.6% x 
2).
    (iii) The 2% QNECs may not be taken into account in determining the 
ADP of the NHCEs because they fail to satisfy the requirements relating 
to section 401(a)(4) set forth in paragraph (a)(6)(ii) of this section. 
This is because the amount of nonelective contributions, excluding those 
QNECs that would be taken into account under the ADP test, would be 2% 
of compensation for the HCEs and 0% for the NHCEs. Therefore, the cash 
or deferred arrangement fails to be a qualified cash or deferred 
arrangement unless the ADP failure is corrected under paragraph (b) of 
this section.
    Example 7. (i) The facts are the same as Example 6, except that 
Employee R receives a QNEC in an amount of $500 and no QNECs are made on 
behalf of the other employees.
    (ii) If the QNEC could be taken into account under paragraph (a)(6) 
of this section, the ADP for the NHCEs would be 2.6% and the plan would 
satisfy the ADP test. The QNEC is disproportionate under paragraph 
(a)(6)(iv) of this section, and cannot be taken into account under 
paragraph (a)(6) of this section, to the extent it exceeds the greater 
of 5% and two times the plan's representative contribution rate (0%), 
multiplied by Employee R's compensation. The plan's representative 
contribution rate is 0% because it is the lowest applicable contribution 
rate among a group of NHCEs that is at least half of all NHCEs, or all 
the NHCEs who are employed on the last day of the plan year. Therefore, 
the QNEC may be taken into account under the ADP test only to the extent 
it does not exceed 5% times Employee R's compensation (or $250) and the 
cash or deferred arrangement fails to satisfy the ADP test and must 
correct under paragraph (b) of this section.
    Example 8. (i) The facts are the same as in Example 4 except that 
the plan changes from the current year testing method to the prior year 
testing method for the following plan year (2007 plan year). The ADP for 
the HCEs for the 2007 plan year is 3.5%.
    (ii) The 2% QNECs may not be taken into account in determining the 
ADP for the NHCEs for the applicable year (2006 plan year) in satisfying 
the ADP test for the 2007 plan year because they were taken into account 
in satisfying the ADP test for the 2006 plan year. Accordingly, the NHCE 
ADP for the applicable year is 0.6%. The elective contributions for the 
plan year fail the requirements of section 401(k) and paragraph (a)(1) 
of this section because the HCE ADP for the plan year (3.5%) exceeds the 
ADP limit of 1.2% (the greater of 0.75% (0.6% x 1.25) and 1.2% (0.6% x 
2)), determined using the applicable year ADP for the NHCEs. Therefore, 
the cash or deferred arrangement fails to be a qualified cash or 
deferred arrangement unless the ADP failure is corrected under paragraph 
(b) of this section.
    Example 9. (i)(A) Employer N maintains Plan X, a profit sharing plan 
that contains a cash or deferred arrangement and that uses the current 
year testing method. Plan X provides for employee contributions, 
elective contributions, and matching contributions. Matching 
contributions on behalf of NHCEs are qualified matching contributions 
(QMACs) and are contributed during the 2005 plan year. Matching 
contributions on behalf of HCEs are not QMACs, because they fail to 
satisfy the nonforfeitability requirement of Sec. 1.401(k)-1(c). The 
elective contributions and matching contributions with respect to HCEs 
for the 2005 plan year are shown in the following table:

----------------------------------------------------------------------------------------------------------------
                                                                                            Matching
                                                            Elective     Total matching   contributions
                                                          contributions   contributions   that are not    QMACs
                                                                                              QMACs
----------------------------------------------------------------------------------------------------------------
Highly compensated employees...........................             15%              5%              5%       0%
----------------------------------------------------------------------------------------------------------------

    (B) The elective contributions and matching contributions with 
respect to the NHCEs for the 2005 plan year are shown in the following 
table:

----------------------------------------------------------------------------------------------------------------
                                                                                            Matching
                                                            Elective     Total matching   contributions
                                                          contributions   contributions   that are not    QMACs
                                                                                              QMACs
----------------------------------------------------------------------------------------------------------------
Nonhighly compensated employees........................             11%              4%              0%       4%
----------------------------------------------------------------------------------------------------------------


[[Page 328]]

    (ii) The plan fails to satisfy the ADP test of section 401(k)(3)(A) 
and paragraph (a)(1) of this section because the ADP for HCEs (15%) is 
more than 125% of the ADP for NHCEs (11%), and more than 2 percentage 
points greater than 11%. However, the plan provides that QMACs may be 
used to meet the requirements of section 401(k)(3)(A)(ii) provided that 
they are not used for any other ADP or ACP test. QMACs equal to 1% of 
compensation are taken into account for each NHCE in applying the ADP 
test. After this adjustment, the applicable ADP and ACP (taking into 
account the provisions of Sec. 1.401(m)-2(a)(5)(ii)) for the plan year 
are as follows:

------------------------------------------------------------------------
                                              Actual          Actual
                                             deferral      contribution
                                            percentage      percentage
------------------------------------------------------------------------
HCEs....................................              15               5
Nonhighly compensated employees.........              12               3
------------------------------------------------------------------------

    (iii) The elective contributions and QMACs taken into account for 
purposes of the ADP test of section 401(k)(3) satisfy the requirements 
of section 401(k)(3)(A)(ii) under paragraph (a)(1)(ii) of this section 
because the ADP for HCEs (15%) is not more than the ADP for NHCEs 
multiplied by 1.25 (12% x 1.25 = 15%).

    (b) Correction of excess contributions--(1) Permissible correction 
methods--(i) In general. A cash or deferred arrangement does not fail to 
satisfy the requirements of section 401(k)(3) and paragraph (a)(1) of 
this section if the employer, in accordance with the terms of the plan 
that includes the cash or deferred arrangement, uses any of the 
following correction methods--
    (A) Qualified nonelective contributions or qualified matching 
contributions. The employer makes qualified nonelective contributions or 
qualified matching contributions that are taken into account under this 
section and, in combination with other amounts taken into account under 
paragraph (a) of this section, allow the cash or deferred arrangement to 
satisfy the requirements of paragraph (a)(1) of this section.
    (B) Excess contributions distributed. Excess contributions are 
distributed in accordance with paragraph (b)(2) of this section.
    (C) Excess contributions recharacterized. Excess contributions are 
recharacterized in accordance with paragraph (b)(3) of this section.
    (ii) Combination of correction methods. A plan may provide for the 
use of any of the correction methods described in paragraph (b)(1)(i) of 
this section, may limit elective contributions in a manner designed to 
prevent excess contributions from being made, or may use a combination 
of these methods, to avoid or correct excess contributions. A plan may 
permit an HCE to elect whether any excess contributions are to be 
recharacterized or distributed. Similarly, a plan may permit an HCE with 
elective contributions for a year that includes both pre-tax elective 
contributions and designated Roth contributions to elect whether the 
excess contributions are to be attributed to pre-tax elective 
contributions or designated Roth contributions. If the plan uses a 
combination of correction methods, any contribution made under paragraph 
(b)(1)(i)(A) of this section must be taken into account before 
application of the correction methods in paragraph (b)(1)(i)(B) or (C) 
of this section.
    (iii) Exclusive means of correction. A failure to satisfy the 
requirements of paragraph (a)(1) of this section may not be corrected 
using any method other than the ones described in paragraphs (b)(1)(i) 
and (ii) of this section. Thus, excess contributions for a plan year may 
not remain unallocated or be allocated to a suspense account for 
allocation to one or more employees in any future year. In addition, 
excess contributions may not be corrected using the retroactive 
correction rules of Sec. 1.401(a)(4)-11(g). See Sec. 1.401(a)(4)-
11(g)(3)(vii) and (5).
    (2) Corrections through distribution--(i) General rule. This 
paragraph (b)(2) contains the rules for correction of excess 
contributions through a distribution from the plan. Correction through a 
distribution generally involves a 4-step process. First, the plan must 
determine, in accordance with paragraph (b)(2)(ii) of this section, the 
total amount of excess contributions that must be distributed under the 
plan. Second, the plan must apportion the total amount of excess 
contributions among HCEs in accordance with paragraph (b)(2)(iii) of 
this section. Third, the plan must determine the income allocable to 
excess contributions in accordance with paragraph (b)(2)(iv) of

[[Page 329]]

this section. Finally, the plan must distribute the apportioned excess 
contributions and allocable income in accordance with paragraph 
(b)(2)(v) of this section. Paragraph (b)(2)(vi) of this section provides 
rules relating to the tax treatment of these distributions. Paragraph 
(b)(2)(vii) provides other rules relating to these distributions.
    (ii) Calculation of total amount to be distributed. The following 
procedures must be used to determine the total amount of the excess 
contributions to be distributed--
    (A) Calculate the dollar amount of excess contributions for each 
HCE. The amount of excess contributions attributable to a given HCE for 
a plan year is the amount (if any) by which the HCE's contributions 
taken into account under this section must be reduced for the HCE's ADR 
to equal the highest permitted ADR under the plan. To calculate the 
highest permitted ADR under a plan, the ADR of the HCE with the highest 
ADR is reduced by the amount required to cause that HCE's ADR to equal 
the ADR of the HCE with the next highest ADR. If a lesser reduction 
would enable the arrangement to satisfy the requirements of paragraph 
(b)(2)(ii)(C) of this section, only this lesser reduction is used in 
determining the highest permitted ADR.
    (B) Determination of the total amount of excess contributions. The 
process described in paragraph (b)(2)(ii)(A) of this section must be 
repeated until the arrangement would satisfy the requirements of 
paragraph (b)(2)(ii)(C) of this section. The sum of all reductions for 
all HCEs determined under paragraph (b)(2)(ii)(A) of this section is the 
total amount of excess contributions for the plan year.
    (C) Satisfaction of ADP. A cash or deferred arrangement satisfies 
this paragraph (b)(2)(ii)(C) if the arrangement would satisfy the 
requirements of paragraph (a)(1)(ii) of this section if the ADR for each 
HCE were determined after the reductions described in paragraph 
(b)(2)(ii)(A) of this section.
    (iii) Apportionment of total amount of excess contributions among 
the HCEs. The following procedures must be used in apportioning the 
total amount of excess contributions determined under paragraph 
(b)(2)(ii) of this section among the HCEs:
    (A) Calculate the dollar amount of excess contributions for each 
HCE. The contributions of the HCE with the highest dollar amount of 
contributions taken into account under this section are reduced by the 
amount required to cause that HCE's contributions to equal the dollar 
amount of the contributions taken into account under this section for 
the HCE with the next highest dollar amount of contributions taken into 
account under this section. If a lesser apportionment to the HCE would 
enable the plan to apportion the total amount of excess contributions, 
only the lesser apportionment would apply.
    (B) Limit on amount apportioned to any individual. For purposes of 
this paragraph (b)(2)(iii), the amount of contributions taken into 
account under this section with respect to an HCE who is an eligible 
employee in more than one plan of an employer is determined by taking 
into account all contributions otherwise taken into account with respect 
to such HCE under any plan of the employer during the plan year of the 
plan being tested as being made under the plan being tested. However, 
the amount of excess contributions apportioned for a plan year with 
respect to any HCE must not exceed the amount of contributions actually 
contributed to the plan for the HCE for the plan year. Thus, in the case 
of an HCE who is an eligible employee in more than one plan of the same 
employer to which elective contributions are made and whose ADR is 
calculated in accordance with paragraph (a)(3)(ii) of this section, the 
amount required to be distributed under this paragraph (b)(2)(iii) shall 
not exceed the contributions actually contributed to the plan and taken 
into account under this section for the plan year.
    (C) Apportionment to additional HCEs. The procedure in paragraph 
(b)(2)(iii)(A) of this section must be repeated until the total amount 
of excess contributions determined under paragraph (b)(2)(ii) of this 
section has been apportioned.
    (iv) Income allocable to excess contributions--(A) General rule. The 
income allocable to excess contributions is equal

[[Page 330]]

to the sum of the allocable gain or loss for the plan year and, to the 
extent the excess contributions are or will be credited with gain or 
loss for the gap period (i.e., the period after the close of the plan 
year and prior to the distribution) if the total account were to be 
distributed, the allocable gain or loss during that period.
    (B) Method of allocating income. A plan may use any reasonable 
method for computing the income allocable to excess contributions, 
provided that the method does not violate section 401(a)(4), is used 
consistently for all participants and for all corrective distributions 
under the plan for the plan year, and is used by the plan for allocating 
income to participant's accounts. See Sec. 1.401(a)(4)-1(c)(8). A plan 
will not fail to use a reasonable method for computing the income 
allocable to excess contributions merely because the income allocable to 
excess contributions is determined on a date that is no more than 7 days 
before the distribution.
    (C) Alternative method of allocating plan year income. A plan may 
allocate income to excess contributions for the plan year by multiplying 
the income for the plan year allocable to the elective contributions and 
other amounts taken into account under this section (including 
contributions made for the plan year), by a fraction, the numerator of 
which is the excess contributions for the employee for the plan year, 
and the denominator of which is the sum of the--
    (1) Account balance attributable to elective contributions and other 
contributions taken into account under this section as of the beginning 
of the plan year, and
    (2) Any additional amount of such contributions made for the plan 
year.
    (D) Safe harbor method of allocating gap period income. A plan may 
use the safe harbor method in this paragraph (b)(2)(iv)(D) to determine 
income on excess contributions for the gap period. Under this safe 
harbor method, income on excess contributions for the gap period is 
equal to 10% of the income allocable to excess contributions for the 
plan year that would be determined under paragraph (b)(2)(iv)(C) of this 
section, multiplied by the number of calendar months that have elapsed 
since the end of the plan year. For purposes of calculating the number 
of calendar months that have elapsed under the safe harbor method, a 
corrective distribution that is made on or before the fifteenth day of a 
month is treated as made on the last day of the preceding month and a 
distribution made after the fifteenth day of a month is treated as made 
on the last day of the month.
    (E) Alternative method for allocating plan year and gap period 
income. A plan may determine the allocable gain or loss for the 
aggregate of the plan year and the gap period by applying the 
alternative method provided by paragraph (b)(2)(iv)(C) of this section 
to this aggregate period. This is accomplished by substituting the 
income for the plan year and the gap period for the income for the plan 
year and by substituting the contributions taken into account under this 
section for the plan year and the gap period for the contributions taken 
into account under this section for the plan year in determining the 
fraction that is multiplied by that income.
    (v) Distribution. Within 12 months after the close of the plan year 
in which the excess contribution arose, the plan must distribute to each 
HCE the excess contributions apportioned to such HCE under paragraph 
(b)(2)(iii) of this section and the allocable income. Except as 
otherwise provided in this paragraph (b)(2)(v) and paragraph (b)(4)(i) 
of this section, a distribution of excess contributions must be in 
addition to any other distributions made during the year and must be 
designated as a corrective distribution by the employer. In the event of 
a complete termination of the plan during the plan year in which an 
excess contribution arose, the corrective distribution must be made as 
soon as administratively feasible after the date of termination of the 
plan, but in no event later than 12 months after the date of 
termination. If the entire account balance of an HCE is distributed 
prior to when the plan makes a distribution of excess contributions in 
accordance with this paragraph (b)(2), the distribution is deemed to 
have been a corrective distribution of excess contributions (and

[[Page 331]]

income) to the extent that a corrective distribution would otherwise 
have been required.
    (vi) Tax treatment of corrective distributions--(A) General rule. 
Except as provided in this paragraph (b)(2)(vi), a corrective 
distribution of excess contributions (and income) that is made within 
2\1/2\ months after the end of the plan year for which the excess 
contributions were made is includible in the employee's gross income on 
the dates the elective contributions would have been received by the 
employee had the employee originally elected to receive the amounts in 
cash, treating the excess contributions that are being distributed as 
the first elective contributions for the plan year. A corrective 
distribution of excess contributions (and income) that is made more than 
2\1/2\ months after the end of the plan year for which the contributions 
were made is includible in the employee's gross income in the employee's 
taxable year in which distributed. Regardless of when the corrective 
distribution is made, it is not subject to the early distribution tax of 
section 72(t). See also paragraph (b)(4) of this section for additional 
rules relating to the employer excise tax on amounts distributed more 
than 2\1/2\ months after the end of the plan year. See also Sec. 
1.402(c)-2, A-4 for restrictions on rolling over distributions that are 
excess contributions.
    (B) Rule for de minimis distributions. If the total amount of excess 
contributions, determined under this paragraph (b)(2), and excess 
aggregate contributions determined under Sec. 1.401(m)-2(b)(2) 
distributed to a recipient under a plan for any plan year is less than 
$100 (excluding income), a corrective distribution of excess 
contributions (and income) is includible in the gross income of the 
recipient in the taxable year of the recipient in which the corrective 
distribution is made, except to the extent provided in paragraph 
(b)(2)(vi)(C) of this section.
    (C) Corrective distributions attributable to designated Roth 
contributions. Notwithstanding paragraphs (b)(2)(vi)(A) and (B) of this 
section, a distribution of excess contributions is not includible in 
gross income to the extent it represents a distribution of designated 
Roth contributions. However, the income allocable to a corrective 
distribution of excess contributions that are designated Roth 
contributions is included in gross income in accordance with paragraph 
(b)(2)(vi)(A) or (B) of this section (i.e., in the same manner as income 
allocable to a corrective distribution of excess contributions that are 
pre-tax elective contributions).
    (vii) Other rules--(A) No employee or spousal consent required. A 
corrective distribution of excess contributions (and income) may be made 
under the terms of the plan without regard to any notice or consent 
otherwise required under sections 411(a)(11) and 417.
    (B) Treatment of corrective distributions as elective contributions. 
Excess contributions are treated as employer contributions for purposes 
of sections 404 and 415 even if distributed from the plan.
    (C) No reduction of required minimum distribution. A distribution of 
excess contributions (and income) is not treated as a distribution for 
purposes of determining whether the plan satisfies the minimum 
distribution requirements of section 401(a)(9). See Sec. 1.401(a)(9)-5, 
A-9(b).
    (D) Partial distributions. Any distribution of less than the entire 
amount of excess contributions (and allocable income) with respect to 
any HCE is treated as a pro rata distribution of excess contributions 
and allocable income.
    (viii) Examples. The following examples illustrate the application 
of this paragraph (b)(2). For purposes of these examples, none of the 
plans provide for catch-up contributions under section 414(v). The 
examples are as follows:

    Example 1. (i) Plan P, a calendar year profit-sharing plan that 
includes a cash or deferred arrangement, provides for distribution of 
excess contributions to HCEs to the extent necessary to satisfy the ADP 
test. For the 2006 plan year, Employee A, an HCE, has elective 
contributions of $12,000 and $200,000 in compensation, for an ADR of 6%, 
and Employee B, a second HCE, has elective contributions of $8,960 and 
compensation of $128,000, for an ADR of 7%. The ADP for the NHCEs is 3% 
for the 2006 plan year. Under the ADP test, the ADP of the two HCEs 
under the plan may not exceed 5% (i.e., 2 percentage points more than 
the ADP of the NHCEs under the plan). The ADP for the 2 HCEs under the 
plan is 6.5%. Therefore,

[[Page 332]]

there must be a correction of excess contributions for the 2006 plan 
year.
    (ii) The total amount of excess contributions for the HCEs is 
determined under paragraph (b)(2)(ii) of this section as follows: the 
elective contributions of Employee B (the HCE with the highest ADR) are 
reduced by $1,280 in order to reduce his ADR to 6% ($7,680/$128,000), 
which is the ADR of Employee A.
    (iii) Because the ADP of the HCEs determined after the $1,280 
reduction to Employee B still exceeds 5%, further reductions in elective 
contributions are necessary in order to reduce the ADP of the HCEs to 
5%. The elective contributions of Employee A and Employee B are each 
reduced by 1% of compensation ($2,000 and $1,280 respectively). Because 
the ADP of the HCEs determined after the reductions equals 5%, the plan 
would satisfy the requirements of (a)(1)(ii) of this section.
    (iv) The total amount of excess contributions ($4,560 = 
$1,280+$2,000+$1,280) is apportioned among the HCEs under paragraph 
(b)(2)(iii) of this section first to the HCE with the highest amount of 
elective contributions. Therefore, Employee A is apportioned $3,040 (the 
amount required to cause Employee A's elective contributions to equal 
the next highest dollar amount of elective contributions).
    (v) Because the total amount of excess contributions has not been 
apportioned, further apportionment is necessary. The balance ($1,520) of 
the total amount of excess contributions is apportioned equally among 
Employee A and Employee B ($760 to each).
    (vi) Therefore, the cash or deferred arrangement will satisfy the 
requirements of paragraph (a)(1) of this section if, by the end of the 
12 month period following the end of the 2006 plan year, Employee A 
receives a corrective distribution of excess contributions equal to 
$3,800 ($3,040 + $760) and allocable income and Employee B receives a 
corrective distribution of $760 and allocable income.
    Example 2. (i) The facts are the same as in Example 1, except 
Employee A's ADR is based on $3,000 of elective contributions to this 
plan and $9,000 of elective contributions to another plan of the 
employer.
    (ii) The total amount of excess contributions ($4,560 = 
$1,280+$2,000+$1,280) is apportioned among the HCEs under paragraph 
(b)(2)(iii) of this section first to the HCE with the highest amount of 
elective contributions. The amount of elective contributions for 
Employee A is $12,000. Therefore, Employee A is apportioned $3,040 (the 
amount required to cause Employee A's elective contributions to equal 
the next highest dollar amount of elective contributions). However, 
pursuant to paragraph (b)(2)(iii)(B) of this section, no more than the 
amount actually contributed to the plan may be apportioned to an HCE. 
Accordingly, no more than $3,000 may be apportioned to Employee A. 
Therefore, the remaining $1,560 must be apportioned to Employee B.
    (iii) The cash or deferred arrangement will satisfy the requirements 
of paragraph (a)(1) of this section if, by the end of the 12 month 
period following the end of the 2006 plan year, Employee A receives a 
corrective distribution of excess contributions equal to $3,000 (total 
amount of elective contributions actually contributed to the plan for 
Employee A) and allocable income and Employee B receives a corrective 
distribution of $1,560 and allocable income.
    Example 3. (i) The facts are the same as in Example 1. The plan 
allocates income on a daily basis. The corrective distributions are made 
in February 2007. The excess contribution that must be distributed to 
Employee A as a corrective distribution is $3,800. This amount must be 
increased (or decreased) to reflect gains (or losses) allocable to that 
amount during the 2006 plan year. The plan uses a reasonable method that 
satisfies paragraph (b)(2)(iv)(B) of this section to determine the gain 
during the 2006 plan year allocable to the $3,800 as $145. Therefore, as 
of the end of the 2006 plan year, the amount of corrective distribution 
that is required would be $3,945.
    (ii) Because the plan allocates income on a daily basis, excess 
contributions are credited with gain or loss during the gap period. 
Therefore, the corrective distribution must include income allocable to 
$3,945 through the date of distribution. For the period from January 1 
through the date of distribution (or if the plan provides 7 days before 
the date of distribution), the income allocable to $3,945 is $105. 
Therefore, the plan will satisfy the requirements of paragraph (a)(1) of 
this section if Employee A receives a corrective distribution of $4,050.
    Example 4. (i) The facts are the same as in Example 1. The plan 
determines plan year income using the alternative method for calculating 
income provided in paragraph (b)(2)(iv)(C) of this section and using the 
portion of the participant's account attributable to elective 
contributions, including elective contributions made for the plan year. 
The plan uses the safe harbor method provided in paragraph (b)(2)(iv)(D) 
of this section for allocating gap period income. The corrective 
distribution is made during the last week of February 2007. At the 
beginning of the 2006 plan year, $100,000 of Employee A's plan account 
represents elective contributions plus attributable earnings. During the 
2006 plan year, $10,000 in elective contributions were contributed to 
the plan for Employee A. The income allocable to Employee A's account 
attributable to elective contributions for the 2006 plan year is $8,000.
    (ii) Therefore, the plan year income allocable to the $3,800 
corrective distribution for

[[Page 333]]

Employee A is $266.65 ($8,000 multiplied by $3,800 divided by $110,000). 
Therefore, as of the end of the 2006 plan year, the amount of corrective 
distribution that is required is $4,066.65. This amount must be 
increased by the gap period income of $53.32 (10% multiplied by $266.65 
(2006 plan year income attributable to the excess contribution) 
multiplied by 2 (number of calendar months since end of 2006 plan year). 
Therefore, the plan will satisfy the requirements of paragraph (a)(1) of 
this section if Employee A receives a corrective distribution of 
$4,119.97.
    Example 5. (i) The facts are the same as in Example 4, except that 
the plan provides for quarterly valuations based on the account balance 
at the end of the quarter.
    (ii) Because the plan's method for allocating income does not 
allocate any income to amounts distributed during the quarter, Employee 
A will not be credited with an allocation of income with respect to the 
amount distributed. Accordingly, Plan P need not plan adjust the 
distribution of excess contribution for income during the gap period and 
thus satisfies paragraph (a)(1) of this section if Employee A receives a 
corrective distribution of $4,066.65.

    (3) Recharacterization of excess contributions--(i) General rule. 
Excess contributions are recharacterized in accordance with this 
paragraph (b)(3) only if the excess contributions that would have to be 
distributed under (b)(2) of this section if the plan was correcting 
through distribution of excess contributions are recharacterized as 
described in paragraph (b)(3)(ii) of this section, and all of the 
conditions set forth in paragraph (b)(3)(iii) of this section are 
satisfied.
    (ii) Treatment of recharacterized excess contributions. 
Recharacterized excess contributions are includible in the employee's 
gross income as if such amounts were distributed under paragraph (b)(2) 
of this section. The recharacterized excess contributions are treated as 
employee contributions for purposes of section 72, sections 401(a)(4), 
401(m), Sec. 1.401(k)-1(d) and Sec. 1.401(k)-2. This requirement is 
not treated as satisfied unless the payor or plan administrator reports 
the recharacterized excess contributions as employee contributions to 
the Internal Revenue Service and the employee by timely providing such 
Federal tax forms and accompanying instructions and timely taking such 
other action as is prescribed by the Commissioner in revenue rulings, 
notices and other guidance published in the Internal Revenue Bulletin 
(see Sec. 601.601(d)(2) of this chapter) as well as the applicable 
Federal tax forms and accompanying instructions.
    (iii) Additional rules--(A) Time of recharacterization. Excess 
contributions may not be recharacterized under this paragraph (b)(3) 
after 2\1/2\ months after the close of the plan year to which the 
recharacterization relates. Recharacterization is deemed to have 
occurred on the date on which the last of those HCEs with excess 
contributions to be recharacterized is notified in accordance with 
paragraph (b)(3)(ii) of this section.
    (B) Employee contributions must be permitted under plan. The amount 
of recharacterized excess contributions, in combination with the 
employee contributions actually made by the HCE, may not exceed the 
maximum amount of employee contributions (determined without regard to 
the ACP test of section 401(m)(2)) permitted under the provisions of the 
plan as in effect on the first day of the plan year.
    (C) Treatment of recharacterized excess contributions. 
Recharacterized excess contributions continue to be treated as employer 
contributions for all purposes under the Internal Revenue Code (other 
than those specified in paragraph (b)(3)(ii) of this section), including 
section 401(a) and sections 404, 409, 411, 412, 415, 416, and 417. Thus, 
for example, recharacterized excess contributions remain subject to the 
requirements of Sec. 1.401(k)-1(c); must be deducted under section 404; 
and are treated as employer contributions described in section 
415(c)(2)(A).
    (4) Rules applicable to all corrections--(i) Coordination with 
distribution of excess deferrals--(A) Treatment of excess deferrals that 
reduce excess contributions. The amount of excess contributions (and 
allocable income) to be distributed under paragraph (b)(2) of this 
section or the amount of excess contributions recharacterized under 
paragraph (b)(3) of this section with respect to an employee for a plan 
year, is reduced by any amounts previously distributed to the employee 
from the plan to correct excess deferrals for the employee's taxable 
year ending with or within the

[[Page 334]]

plan year in accordance with section 402(g)(2).
    (B) Treatment of excess contributions that reduce excess deferrals. 
Under Sec. 1.402(g)-1(e), the amount required to be distributed to 
correct an excess deferral to an employee for a taxable year is reduced 
by any excess contributions (and allocable income) previously 
distributed or excess contributions recharacterized with respect to the 
employee for the plan year beginning with or within the taxable year. 
The amount of excess contributions includible in the gross income of the 
employee, and the amount of excess contributions reported by the payer 
or plan administrator as includible in the gross income of the employee, 
does not include the amount of any reduction under Sec. 1.402(g)-
1(e)(6).
    (ii) Forfeiture of match on distributed excess contributions. A 
matching contribution is taken into account under section 401(a)(4) even 
if the match is with respect to an elective contribution that is 
distributed or recharacterized under this paragraph (b). This requires 
that, after correction of excess contributions, each level of matching 
contributions be currently and effectively available to a group of 
employees that satisfies section 410(b). See Sec. 1.401(a)(4)-
4(e)(3)(iii)(G). Thus, a plan that provides the same rate of matching 
contributions to all employees will not meet the requirements of section 
401(a)(4) if elective contributions are distributed under this paragraph 
(b) to HCEs to the extent needed to meet the requirements of section 
401(k)(3), while matching contributions attributable to those elective 
contributions remain allocated to the HCEs' accounts. Under section 
411(a)(3)(G) and Sec. 1.411(a)-4(b)(7), a plan may forfeit matching 
contributions attributable to excess contributions, excess aggregate 
contributions or excess deferrals to avoid a violation of section 
401(a)(4). See also Sec. 1.401(a)(4)-11(g)(3)(vii)(B) regarding the use 
of additional allocations to the accounts of NHCEs for the purpose of 
correcting a discriminatory rate of matching contributions.
    (iii) Permitted forfeiture of QMAC. Pursuant to section 
401(k)(8)(E), a qualified matching contribution is not treated as 
forfeitable under Sec. 1.401(k)-1(c) merely because under the plan it 
is forfeited in accordance with paragraph (b)(4)(ii) of this section.
    (iv) No requirement for recalculation. If excess contributions are 
distributed or recharacterized in accordance with paragraphs (b)(2) and 
(3) of this section, the cash or deferred arrangement is treated as 
meeting the nondiscrimination test of section 401(k)(3) regardless of 
whether the ADP for the HCEs, if recalculated after the distributions or 
recharacterizations, would satisfy section 401(k)(3).
    (v) Treatment of excess contributions that are catch-up 
contributions. A cash or deferred arrangement does not fail to meet the 
requirements of section 401(k)(3) and paragraph (a)(1) of this section 
merely because excess contributions that are catch-up contributions 
because they exceed the ADP limit, as described in Sec. 1.414(v)-
1(b)(1)(iii), are not corrected in accordance with this paragraph (b).
    (5) Failure to timely correct--(i) Failure to correct within 2\1/2\ 
months after end of plan year. If a plan does not correct excess 
contributions within 2\1/2\ months after the close of the plan year for 
which the excess contributions are made, the employer will be liable for 
a 10% excise tax on the amount of the excess contributions. See section 
4979 and Sec. 54.4979-1 of this chapter. Qualified nonelective 
contributions and qualified matching contributions properly taken into 
account under paragraph (a)(6) of this section for a plan year may 
enable a plan to avoid having excess contributions, even if the 
contributions are made after the close of the 2\1/2\ month period.
    (ii) Failure to correct within 12 months after end of plan year. If 
excess contributions are not corrected within 12 months after the close 
of the plan year for which they were made, the cash or deferred 
arrangement will fail to satisfy the requirements of section 401(k)(3) 
for the plan year for which the excess contributions are made and all 
subsequent plan years during which the excess contributions remain in 
the trust.
    (c) Additional rules for prior year testing method--(1) Rules for 
change in testing method--(i) General rule. A plan is permitted to 
change from the prior

[[Page 335]]

year testing method to the current year testing method for any plan 
year. A plan is permitted to change from the current year testing method 
to the prior year testing method only in situations described in 
paragraph (c)(1)(ii) of this section. For purposes of this paragraph 
(c)(1), a plan that uses the safe harbor method described in Sec. 
1.401(k)-3 or a SIMPLE 401(k) plan is treated as using the current year 
testing method for that plan year.
    (ii) Situations permitting a change to the prior year testing 
method. The situations described in this paragraph (c)(1)(ii) are:
    (A) The plan is not the result of the aggregation of two or more 
plans, and the current year testing method was used under the plan for 
each of the 5 plan years preceding the plan year of the change (or if 
lesser, the number of plan years the plan has been in existence, 
including years in which the plan was a portion of another plan).
    (B) The plan is the result of the aggregation of two or more plans, 
and for each of the plans that are being aggregated (the aggregating 
plans), the current year testing method was used for each of the 5 plan 
years preceding the plan year of the change (or if lesser, the number of 
plan years since that aggregating plan has been in existence, including 
years in which the aggregating plan was a portion of another plan).
    (C) A transaction described in section 410(b)(6)(C)(i) and Sec. 
1.410(b)-2(f) occurs and--
    (1) As a result of the transaction, the employer maintains both a 
plan using the prior year testing method and a plan using the current 
year testing method; and
    (2) The change from the current year testing method to the prior 
year testing method occurs within the transition period described in 
section 410(b)(6)(C)(ii).
    (2) Calculation of ADP under the prior year testing method for the 
first plan year--(i) Plans that are not successor plans. If, for the 
first plan year of any plan (other than a successor plan), the plan uses 
the prior year testing method, the plan is permitted to use either that 
first plan year as the applicable year for determining the ADP for 
eligible NHCEs, or use 3% as the ADP for eligible NHCEs, for applying 
the ADP test for that first plan year. A plan (other than a successor 
plan) that uses the prior year testing method but has elected for its 
first plan year to use that year as the applicable year is not treated 
as changing its testing method in the second plan year and is not 
subject to the limitations on double counting on QNECs under paragraph 
(a)(6)(vi) of this section for the second plan year.
    (ii) First plan year defined. For purposes of this paragraph (c)(2), 
the first plan year of any plan is the first year in which the plan 
provides for elective contributions. Thus, the rules of this paragraph 
(c)(2) do not apply to a plan (within the meaning of Sec. 1.410(b)-
7(b)) for a plan year if for such plan year the plan is aggregated under 
Sec. 1.401(k)-1(b)(4) with any other plan that provided for elective 
contributions in the prior year.
    (iii) Successor plans. A plan is a successor plan if 50% or more of 
the eligible employees for the first plan year were eligible employees 
under a qualified cash or deferred arrangement maintained by the 
employer in the prior year. If a plan that is a successor plan uses the 
prior year testing method for its first plan year, the ADP for the group 
of NHCEs for the applicable year must be determined under paragraph 
(c)(4) of this section.
    (3) Plans using different testing methods for the ADP and ACP test. 
Except as otherwise provided in this paragraph (c)(3), a plan may use 
the current year testing method or prior year testing method for the ADP 
test for a plan year without regard to whether the current year testing 
method or prior year testing method is used for the ACP test for that 
year. For example, a plan may use the prior year testing method for the 
ADP test and the current year testing method for its ACP test for the 
plan year. However, plans that use different testing methods under this 
paragraph (c)(3) cannot use--
    (i) The recharacterization method of paragraph (b)(3) of this 
section to correct excess contributions for a plan year;

[[Page 336]]

    (ii) The rules of Sec. 1.401(m)-2(a)(6)(ii) to take elective 
contributions into account under the ACP test (rather than the ADP 
test); or
    (iii) The rules of paragraph (a)(6)(v) of this section to take 
qualified matching contributions into account under the ADP test (rather 
than the ACP test).
    (4) Rules for plan coverage changes--(i) In general. A plan that 
uses the prior year testing method and experiences a plan coverage 
change during a plan year satisfies the requirements of this section for 
that year only if the plan provides that the ADP for the NHCEs for the 
plan year is the weighted average of the ADPs for the prior year 
subgroups.
    (ii) Optional rule for minor plan coverage changes. If a plan 
coverage change occurs and 90% or more of the total number of the NHCEs 
from all prior year subgroups are from a single prior year subgroup, 
then, in lieu of using the weighted averages described in paragraph 
(c)(4)(i) of this section, the plan may provide that the ADP for the 
group of eligible NHCEs for the prior year under the plan is the ADP of 
the NHCEs for the prior year of the plan under which that single prior 
year subgroup was eligible.
    (iii) Definitions. The following definitions apply for purposes of 
this paragraph (c)(4):
    (A) Plan coverage change. The term plan coverage change means a 
change in the group or groups of eligible employees under a plan on 
account of--
    (1) The establishment or amendment of a plan;
    (2) A plan merger or spinoff under section 414(l);
    (3) A change in the way plans (within the meaning of Sec. 1.410(b)-
7(b)) are combined or separated for purposes of Sec. 1.401(k)-1(b)(4) 
(e.g., permissively aggregating plans not previously aggregated under 
Sec. 1.410(b)-7(d), or ceasing to permissively aggregate plans under 
Sec. 1.410(b)-7(d));
    (4) A reclassification of a substantial group of employees that has 
the same effect as amending the plan (e.g., a transfer of a substantial 
group of employees from one division to another division); or
    (5) A combination of any of paragraphs (c)(4)(iii)(A)(1) through (4) 
of this section.
    (B) Prior year subgroup. The term prior year subgroup means all 
NHCEs for the prior plan year who, in the prior year, were eligible 
employees under a specific plan maintained by the employer that included 
a qualified cash or deferred arrangement and who would have been 
eligible employees in the prior year under the plan being tested if the 
plan coverage change had first been effective as of the first day of the 
prior plan year instead of first being effective during the plan year. 
The determination of whether an NHCE is a member of a prior year 
subgroup is made without regard to whether the NHCE terminated 
employment during the prior year.
    (C) Weighted average of the ADPs for the prior year subgroups. The 
term weighted average of the ADPs for the prior year subgroups means the 
sum, for all prior year subgroups, of the adjusted ADPs for the plan 
year. The term adjusted ADP with respect to a prior year subgroup means 
the ADP for the prior plan year of the specific plan under which the 
members of the prior year subgroup were eligible employees on the first 
day of the prior plan year, multiplied by a fraction, the numerator of 
which is the number of NHCEs in the prior year subgroup and denominator 
of which is the total number of NHCEs in all prior year subgroups.
    (iv) Examples. The following examples illustrate the application of 
this paragraph (c)(4):
    Example 1. (i) Employer B maintains two calendar year plans, Plan O 
and Plan P, each of which includes a cash or deferred arrangement. The 
plans were not permissively aggregated under Sec. 1.410(b)-7(d) for the 
2005 plan year. Both plans use the prior year testing method. Plan O had 
300 eligible employees who were NHCEs for the 2005 plan year, and their 
ADP for that year was 6%. Sixty of the eligible employees who were NHCEs 
for the 2005 plan year under Plan O, terminated their employment during 
that year. Plan P had 100 eligible employees who were NHCEs for 2005, 
and the ADP for those NHCEs for that plan was 4%. Plan O and Plan P are 
permissively aggregated under Sec. 1.410(b)-7(d) for the 2006 plan 
year.
    (ii) The permissive aggregation of Plan O and Plan P for the 2006 
plan year under Sec. 1.410(b)-7(d) is a plan coverage change that

[[Page 337]]

results in treating the plans as one plan (Plan OP) for purposes of 
Sec. 1.401(k)-1(b)(4). Therefore, the prior year ADP for the NHCEs 
under Plan OP for the 2006 plan year is the weighted average of the ADPs 
for the prior year subgroups: the Plan O prior year subgroup and the 
Plan P prior year subgroup.
    (iii) The Plan O prior year subgroup consists of the 300 employees 
who, in the 2005 plan year, were eligible NHCEs under Plan O and who 
would have been eligible under Plan OP for the 2005 plan year if Plan O 
and Plan P had been permissively aggregated for that plan year. The Plan 
P prior year subgroup consists of the 100 employees who, in the 2005 
plan year, were eligible NHCEs under Plan P and would have been eligible 
under Plan OP for the 2005 plan year if Plan O and Plan P had been 
permissively aggregated for that plan year.
    (iv) The weighted average of the ADPs for the prior year subgroups 
is the sum of the adjusted ADP for the Plan O prior year subgroup and 
the adjusted ADP for the Plan P prior year subgroup. The adjusted ADP 
for the Plan O prior year subgroup is 4.5%, calculated as follows: 6% 
(the ADP for the NHCEs under Plan O for the 2005 plan year) x 300/400 
(the number of NHCEs in the Plan O prior year subgroup divided by the 
total number of NHCEs in all prior year subgroups). The adjusted ADP for 
the Plan P prior year subgroup is 1%, calculated as follows: 4% (the ADP 
for the NHCEs under Plan P for the 2005 plan year) x 100/400 (the number 
of NHCEs in the Plan P prior year subgroup divided by the total number 
of NHCEs in all prior year subgroups). Thus, the prior year ADP for 
NHCEs under Plan OP for the 2006 plan year is 5.5% (the sum of adjusted 
ADPs for the prior year subgroups, 4.5% plus 1%).
    (v) As provided in paragraph (c)(4)(iii)(B) of this section, the 
determination of whether an NHCE is a member of a prior year subgroup is 
made without regard to whether that NHCE terminated employment during 
the prior year. Thus, the prior ADP for the NHCEs under Plan OP for the 
2006 plan year is unaffected by the termination of the 60 NHCEs covered 
by Plan O during the 2005 plan year.
    Example 2. (i) The facts are the same as Example 1, except that the 
60 employees who terminated employment during the 2005 plan are instead 
spun-off to another plan.
    (ii) The permissive aggregation of Plan O and Plan P for the 2006 
plan year under Sec. 1.410(b)-7(d) is a plan coverage change that 
results in treating the plans as one plan (Plan OP) for purposes of 
Sec. 1.401(k)-1(b)(4) and the spin-off of the 60 employees is a plan 
coverage change. Therefore, the prior year ADP for the NHCEs under Plan 
OP for the 2006 plan year is the weighted average of the ADPs for the 
prior year subgroups: the Plan O prior year subgroup and the Plan P 
prior year subgroup.
    (iii) For purposes of determining the prior year subgroups, the 
employees who would have been eligible employees in the prior year under 
the plan being tested are determined as if both plan coverage changes 
had first been effective as of the first day of the prior plan year. The 
Plan O prior year subgroup consists of the 240 employees who, in the 
2005 plan year, were eligible NHCEs under Plan O and would have been 
eligible under Plan OP for the 2005 plan year if the spin-off had 
occurred at the beginning of the 2005 plan year and Plan O and Plan P 
had been permissively aggregated under Sec. 1.410(b)-7(d) for that plan 
year. The Plan P prior year subgroup consists of the 100 employees who, 
in the 2005 plan year, were eligible NHCEs under Plan P and would have 
been eligible under Plan OP for the 2005 plan year if Plan O and Plan P 
had been permissively aggregated under Sec. 1.410(b)-7(d) for that plan 
year.
    (iv) The weighted average of the ADPs for the prior year subgroups 
is the sum of the adjusted ADP with respect to the prior year subgroup 
consisting of eligible NHCEs from Plan O and the adjusted ADP with 
respect to the prior year subgroup consisting of eligible NHCEs from 
Plan P. The adjusted ADP for the prior year subgroup consisting of 
eligible NHCEs under Plan O is 4.23%, calculated as follows: 6% (the ADP 
for the NHCEs under Plan O for the 2005 plan year) x 240/340 (the number 
of NHCEs in that prior year subgroup divided by the total number of 
NHCEs in all prior year subgroups). The adjusted ADP for the prior year 
subgroup consisting of the eligible NHCEs from Plan P is 1.18%, 
calculated as follows: 4% (the ADP for the NHCEs under Plan P for the 
2005 plan year) x 100/340 (the number of NHCEs in that prior year 
subgroup divided by the total number of NHCEs in all prior year 
subgroups). Thus, the prior year ADP for NHCEs under Plan OP for the 
2006 plan year is 5.41% (the sum of adjusted ADPs for the prior year 
subgroups, 4.23% plus 1.18%).
    Example 3. (i) The facts are the same as in Example 1, except that 
instead of Plan O and Plan P being permissively aggregated for the 2006 
plan year, 200 of the employees eligible under Plan O were spun-off from 
Plan O and merged into Plan P.
    (ii) The spin-off from Plan O and merger to Plan P for the 2006 plan 
year are plan coverage changes for Plan P. Therefore, the prior year ADP 
for the NHCEs under Plan P for the 2006 plan year is the weighted 
average of the ADPs for the prior year subgroups under Plan P. There are 
2 subgroups under Plan P for the 2006 plan year. The Plan O prior year 
subgroup consists of the 200 employees who, in the 2005 plan year, were 
eligible NHCEs under Plan O and who would have been eligible under Plan 
P for the 2005 plan year if the spin-off and merger had occurred on the 
first day of the 2005 plan year. The

[[Page 338]]

Plan P prior year subgroup consists of the 100 employees who, in the 
2005 plan year, were eligible NHCEs under Plan P for the 2005 plan year.
    (iii) The weighted average of the ADPs for the prior year subgroups 
is the sum of the adjusted ADP for the Plan O prior year subgroup and 
the adjusted ADP for the Plan P prior year subgroup. The adjusted ADP 
for the Plan O prior year subgroup is 4.0%, calculated as follows: 6% 
(the ADP for the NHCEs under Plan O for the 2005 plan year) x 200/300 
(the number of NHCEs in the Plan O prior year subgroup divided by the 
total number of NHCEs in all prior year subgroups). The adjusted ADP for 
the Plan P prior year subgroup is 1.33%, calculated as follows: 4% (the 
ADP for the NHCEs under Plan P for the 2005 plan year) x 100/300 (the 
number of NHCEs in the Plan P prior year subgroup divided by the total 
number of NHCEs in all prior year subgroups). Thus, the prior year ADP 
for NHCEs under Plan P for the 2006 plan year is 5.33% (the sum of 
adjusted ADPs for the 2 prior year subgroups, 4.0% plus 1.33%).
    (iv) The spin-off from Plan O for the 2006 plan year is a plan 
coverage change for Plan O. Therefore, the prior year ADP for the NHCEs 
under Plan O for the 2006 plan year is the weighted average of the ADPs 
for the prior year subgroups under Plan O. In this case, there is only 
one prior year subgroup under Plan O, the employees who were NHCEs of 
Employer B for the 2005 plan year and who were eligible for the 2005 
plan year under Plan O. Because there is only one prior year subgroup 
under Plan O, the weighted average of the ADPs for the prior year 
subgroup under Plan O is equal to the NHCE ADP for the prior year (2005 
plan year) under Plan O, or 6%.
    Example 4. (i) Employer C maintains a calendar year plan, Plan Q, 
which includes a cash or deferred arrangement that uses the prior year 
testing method. Plan Q covers employees of Division A and Division B. In 
2005, Plan Q had 500 eligible employees who were NHCEs, and the ADP for 
those NHCEs for 2005 was 2%. Effective January 1, 2006, Employer C 
amends the eligibility provisions under Plan Q to exclude employees of 
Division B effective January 1, 2006. In addition, effective on that 
same date, Employer C establishes a new calendar year plan, Plan R, 
which includes a cash or deferred arrangement that uses the prior year 
testing method. The only eligible employees under Plan R are the 100 
employees of Division B who were eligible employees under Plan Q.
    (ii) Plan R is a successor plan, within the meaning of paragraph 
(c)(2)(iii) of this section (because all of the employees were eligible 
employees under Plan Q in the prior year). Therefore, Plan R cannot use 
the first plan year rule set forth in paragraph (c)(2)(i) of this 
section.
    (iii) The amendment to the eligibility provisions of Plan Q and the 
establishment of Plan R are plan coverage changes within the meaning of 
paragraph (c)(4)(iii)(A) of this section for Plan Q and Plan R. 
Accordingly, each plan must determine the NHCE ADP for the 2006 plan 
year under the rules set forth in paragraph (c)(4) of this section.
    (iv) The prior year ADP for NHCEs under Plan Q is the weighted 
average of the ADPs for the prior year subgroups. Plan Q has only one 
prior year subgroup (because the only NHCEs who would have been eligible 
employees under Plan Q for the 2005 plan year if the amendment to the 
Plan Q eligibility provisions had occurred as of the first day of that 
plan year were eligible employees under Plan Q). Therefore, for purposes 
of the 2006 plan year under Plan Q, the ADP for NHCEs for the prior year 
is the weighted average of the ADPs for the prior year subgroups, or 2%, 
the same as if the plan amendment had not occurred.
    (v) Similarly, Plan R has only one prior year subgroup (because the 
only NHCEs who would have been eligible employees under Plan R for the 
2005 plan year if the plan were established as of the first day of that 
plan year were eligible employees under Plan Q). Therefore, for purposes 
of the 2006 testing year under Plan R, the ADP for NHCEs for the prior 
year is the weighted average of the ADPs for the prior year subgroups, 
or 2%, the same as that of Plan Q.
    Example 5. (i) The facts are the same as in Example 4, except that 
the provisions of Plan R extend eligibility to 50 hourly employees who 
previously were not eligible employees under any qualified cash or 
deferred arrangement maintained by Employer C.
    (ii) Plan R is a successor plan (because 100 of Plan R's 150 
eligible employees were eligible employees under another qualified cash 
or deferred arrangement maintained by Employer C in the prior year). 
Therefore, Plan R cannot use the first plan year rule set forth in 
paragraph (c)(2)(i) of this section.
    (iii) The establishment of Plan R is a plan coverage change that 
affects Plan R. Because the 50 hourly employees were not eligible 
employees under any qualified cash or deferred arrangement of Employer C 
for the prior plan year, they do not comprise a prior year subgroup. 
Accordingly, Plan R still has only one prior year subgroup. Therefore, 
for purposes of the 2006 testing year under Plan R, the ADP for NHCEs 
for the prior year is the weighted average of the ADPs for the prior 
year subgroups, or 2%, the same as that of Plan Q.
