Rev. Proc. 2007-37

SECTION 1. PURPOSE

The purpose of this revenue procedure is to set forth the procedure by which the
sponsor of a defined benefit plan, other than a multiemployer plan, may request
and obtain approval for the use of plan-specific substitute mortality tables in
accordance with § 430(h)(3)(C) of the Internal Revenue Code (Code) and section
303(h)(3)(C) of the Employee Retirement Income Security Act of 1974, as
amended (ERISA).

SECTION 2. BACKGROUND INFORMATION

.01 Section 412 of the Code provides minimum funding requirements for defined
benefit pension plans. Section 430, which was added by the Pension
Protection Act of 2006, Pub. L. No. 109-280, 120 Stat. 780, specifies the
minimum funding requirements for defined benefit plans other than
multiemployer plans pursuant to § 412 and is generally effective for plan
years beginning on or after January 1, 2008. Section 430(h)(3)(A) sets forth
rules regarding the use of generally applicable mortality tables for purposes of
§ 430. Section 430(h)(3)(C) and section 303(h)(3)(C) of ERISA provide that
the Secretary of the Treasury may approve substitute mortality tables to be
used in determining any present value or making any computation under
those sections for a period not to exceed ten years. Mortality tables meet the
requirements for substitute mortality tables if the pension plan has a sufficient
number of plan participants and the plan has been maintained for a sufficient
period of time in order to have credible mortality experience, and such tables
reflect the actual experience of the plan and projected trends in general
mortality experience of participants in pension plans. Except as provided by
the Secretary, a plan sponsor cannot use substitute mortality tables for any
plan unless substitute mortality tables are established and used for each
other plan subject to § 430 of the Code that is maintained by the plan sponsor
and the plan sponsor’s controlled group.

.02 Proposed regulation § 1.430(h)(3)-1, which sets forth proposed rules
regarding the use of generally applicable mortality tables for purposes of
§ 430, and proposed regulation § 1.430(h)(3)-2, which sets forth proposed

2
rules for the use of substitute mortality tables under § 430(h)(3)(C) (referred
to elsewhere in this revenue procedure as the “proposed regulations”), were
published in the Federal Register on May 29, 2007, at 72 FR 29456. Under
the proposed regulations, substitute mortality tables must reflect the actual
mortality experience of the pension plan maintained by the plan sponsor for
which the tables are to be used and that mortality experience must be
credible. Separate mortality tables must be established for each gender
under the plan, and a substitute mortality table is permitted to be established
for a gender only if the plan has credible mortality experience with respect to
that gender. If the mortality experience for one gender is credible but the
mortality experience for the other gender is not credible, then the substitute
mortality tables are used for the gender that has credible mortality
experience, and the mortality tables under proposed regulation § 1.430(h)(3)-
1 are used for the gender that does not have credible mortality experience. If
separate mortality tables under § 430(h)(3)(D) are used for certain disabled
individuals under a plan, then those individuals are disregarded for all
purposes with respect to substitute mortality tables under § 430(h)(3)(C).
Thus, if the mortality tables under § 430(h)(3)(D) are used for certain disabled
individuals under a plan, mortality experience with respect to those individuals
must be excluded in determining mortality rates for substitute mortality tables
with respect to a plan.

Under the proposed regulations, a substitute mortality table is based on
credible mortality experience for a gender within a plan if and only if the
mortality experience is based on at least 1,000 deaths within that gender over
the period covered by the experience study. The experience study must be
based on mortality experience data over a 2, 3, or 4-consecutive year period,
the last day of which must be less than 3 years before the first day of the first
plan year for which the substitute mortality tables are to apply.

Development of a substitute mortality table under the proposed regulations
requires creation of a base table (Base Table) and identification of a base
year (Base Year), which are then used to determine generational substitute
mortality tables. The Base Table must be developed from a study of the
mortality experience of the plan using amounts-weighted data. The proposed
regulations also set forth rules regarding development of amounts-weighted
mortality rates for an age and the determination of the Base Year. The
proposed regulations provide that amounts-weighted mortality rates may be
derived from amounts-weighted mortality rates for age groups.

The proposed regulations provide that Base Tables may be constructed either
directly through graduation of amounts-weighted mortality rates or indirectly
by applying a level percentage to tables prescribed by § 430(h)(3)(A),
provided that the resulting tables sufficiently reflect the plan’s mortality
experience. The Service may permit the construction of Base Tables through
application of a level percentage to other recognized mortality tables, applying

3
similar standards to ensure that the resulting tables are sufficiently reflective
of the plan’s mortality experience.

As noted above, except as provided by the Secretary, a plan sponsor cannot
use substitute mortality tables for any plan unless substitute mortality tables
are established and used for each other plan subject to § 430 that is
maintained by the plan sponsor and the plan sponsor’s controlled group.
Under the proposed regulations, the use of substitute mortality tables for one
plan would not be prohibited merely because another plan maintained by the
plan sponsor (or by a member of the plan sponsor’s controlled group) cannot
use substitute mortality tables because neither the males nor the females
under that other plan have credible mortality experience for a plan year.
Thus, if a sponsor’s controlled group maintains two pension plans subject to
§ 430, each of which has credible mortality experience for at least one
gender, then either both plans must obtain approval from the Service to use
substitute mortality tables or neither plan may use substitute mortality tables.
By contrast, if, for one of those plans, neither males nor females have
credible mortality experience, then the plan without credible mortality
experience will not interfere with the ability of the plan with credible mortality
experience to use substitute mortality tables.

SECTION 3. GENERAL ADMINISTRATIVE PROCEDURES

.01 Compliance with Regulations
. Until final regulations under § 430(h)(3)(C) are
issued, requests for the use of substitute mortality tables must satisfy the
requirements of proposed regulation § 1.430(h)(3)-2. After those final
regulations are issued, requests must satisfy the requirements of the final
regulations.

.02 Submission
. Requests for the use of substitute mortality tables must be
submitted to:

Internal Revenue Service
Attention: EP Letter Rulings
P.O. Box 27063
McPherson Station
Washington, D.C. 20038

The user fee required by section 6.01(10) (All other letter rulings) of Rev.
Proc. 2007-8, 2007-1 I.R.B. 230, or its successors, must be sent with such
requests.

.03 Necessary Procedural Documents
. A request will not be considered unless it
complies with (1) through (3) below.

4
(1) The request (and any subsequently provided additional information) must be
signed by the employer maintaining the plan(s) (the "applicant") or an
authorized representative of the applicant who must be identified in (a), (b),
(c), (d) or (e) of section 9.02(11) of Rev. Proc. 2007-4, 2007-1 I.R.B. 118, or
its successors. Where an authorized representative signs the request or will
appear before the Service in connection with the request, a properly signed
and dated Form 2848, Power of Attorney and Declaration of Representative,
must be submitted with the request. An individual is not an authorized
representative of the applicant merely on account of being the administrator
or trustee of the plan.

(2) The request also must contain a declaration in the following form: "Under
penalties of perjury, I declare that I have examined this request, or this
modification to the request, including accompanying documents, and, to the
best of my knowledge and belief, the request or the modification contains all
the relevant facts relating to the request, and such facts are true, correct, and
complete." This declaration must be signed by the applicant (e.g., an
authorized officer of a corporation). The signature of an individual with a
power of attorney will not suffice for the declaration. See section 9.02(13) of
Rev. Proc. 2007-4.

(3) Because a request for the use of substitute mortality tables constitutes a
request for a ruling, compliance with § 6110 of the Code is also required.
Section 601.201 of the Statement of Procedural Rules sets forth the
requirements applicable to requests for rulings and determination letters
which are subject to § 6110. Section 601.201(e) furnishes specific
instructions to applicants.

The applicant must provide with the request either a statement of proposed
deletions and the statutory basis for each proposed deletion, or a statement
that no information other than names, addresses, and taxpayer identifying
numbers need be deleted.

.04 Checklist
. A checklist has been provided in Appendix A for the convenience
of the applicant submitting the request. This checklist should be signed, by
the applicant or authorized representative, and dated and placed on top of the
request.

SECTION 4. DEADLINE FOR REQUESTING THE USE OF SUBSTITUTE
MORTALITY TABLES

.01 In General
. A request for the use of substitute mortality tables generally must
be submitted at least 7 months prior to the first day of the first plan year for
which the substitute mortality tables are to apply. Thus, for example, if the
first plan year to which substitute mortality tables are to apply is the plan year
that begins January 1, 2009, then the deadline is June 1, 2008.

5
Notwithstanding the generally applicable deadline, a request to use substitute
mortality tables is timely if it is submitted on or before October 1, 2007.

.02 Incomplete Requests
. Generally, an incomplete request for the use of
substitute mortality tables will be summarily denied absent mutual agreement
of the Service and the applicant to extend the 180-day period specified under
§ 430(h)(3)(C)(v)(II). Except as provided in section 5.06 of this revenue
procedure, the applicant should not assume that the Service will agree to
extend the 180-day period for a request that does not include substantially all
of the applicable information specified in sections 5 through 13 of this revenue
procedure.

SECTION 5. GENERAL RULES

.01 The Service will deny a request if the request fails to meet the requirements
of this revenue procedure or if the Service determines that a substitute
mortality table does not sufficiently reflect the mortality experience of the
applicable plan population.

.02 If separate mortality tables are used for disabled individuals pursuant to
§ 430(h)(3)(D), then those individuals are disregarded for all purposes under
this revenue procedure.

.03 A separate request must be made with respect to each plan (the “Plan”), or
group of plans that are permissively aggregated (the “Permissive Group”), for
which the use of a substitute mortality table or tables is requested. The
request must include a complete copy of the Base Tables that will form the
basis for the substitute mortality tables that will be used. The request must
state the first day of the first plan year for which the substitute mortality tables
are to be applicable (the “Requested Effective Plan Year”) and must state the
term of years (not more than 10) that the tables are requested to be used.
Each request also must identify the Base Year of the Base Tables.

.04 The request must include a description of the populations within the Plan (or
the Permissive Group) for which the use of substitute mortality tables is
requested and a description of the populations, if any, for which the use of
substitute mortality tables is not requested.

For example, if the use of substitute mortality tables is requested for
nondisabled female individuals (but for no other individuals) where separate
mortality tables are used for disabled individuals pursuant to § 430(h)(3)(D),
then the population for whom the use of substitute mortality tables is
requested would be described as “Nondisabled Females” and the population
for whom the use of substitute mortality tables is not requested would be
described as “Nondisabled Males.”

6
Similarly, if the use of substitute mortality tables is requested for male
annuitants (but not male non-annuitants) and for females on a combined
annuitant/nonannuitant basis, in each case including disabled individuals,
then the populations for whom the use of substitute mortality tables is
requested would be described as “Male Annuitants” and “Females”, and the
population for whom the use of substitute mortality tables is not requested
would be described as “Male Nonannuitants.”

.05 The request must include the plan identification information described in
Section 6, the credible mortality experience demonstrations described in
Section 7, the stability demonstrations described in Section 8, the lack of
credible mortality experience demonstrations described in Section 9, the
unadjusted mortality experience described in Section 10, the Base Table
construction methods as set forth in Section 11 or 12, and the demonstrations
with respect to the Base Tables described in Section 13.

.06 If there are other plans subject to § 430 maintained by the applicant, or
members of the applicant’s controlled group, that have credible mortality
experience for which the use of substitute mortality tables will be requested in
a separate request, then the Service will not summarily deny the request for
the use of substitute mortality tables on the grounds that all plans with
credible mortality experience maintained by the applicant would not be using
substitute mortality tables, but only if the applicant requests that the 180-day
review period provided under § 430(h)(3)(C)(v)(II) not begin for the initial
request and any such separate request until the date all such separate
requests have been received, and only if those separate requests are
submitted within 90 days after the receipt of the initial request (and no later
than the deadline that applies to each such separate request under section 4
of this revenue procedure). In the absence of such a request for a delay in
the start of the 180-day review period, or if all such separate requests are not
submitted within 90 days after the receipt of the initial request, the Service will
summarily deny the request for the use of substitute mortality tables on the
grounds that all plans with credible mortality experience maintained by the
applicant would not be using substitute mortality tables.

Example
. Employer E maintains Plans A and B, both of which are calendar
year plans that have each had over 2,500 deaths in each of the last five
years. Employer E submits a request for the use of substitute mortality tables
for Plan A for the 2009 plan year that is received on February 15, 2008 (the
“A Request”). To avoid denial of the A Request on the grounds that all plans
with credible mortality experience maintained by the applicant would not be
using substitute mortality tables, Employer E requests that the 180-day review
period of the A Request not begin until the receipt of a separate request for
the 2009 plan year from Employer E for the use of substitute mortality tables
by Plan B. The Service agrees to defer commencement of the 180-day
period, but will summarily deny the application unless Employer E submits a

7
separate request for the use of substitute mortality tables for Plan B no later
than May 15, 2008.

.07 If two or more plans are permissively aggregated for the purpose of
constructing substitute mortality tables, then such plans are treated as a
single plan for all purposes of this revenue procedure. Accordingly, if two or
more plans are permissively aggregated, then all populations within the plans
must be so aggregated.

Example
. Employer F maintains Plans C, D, and E, each of which had 500
male deaths and 100 female deaths in each of the last five years. Employer
F may request to use one substitute male mortality table and one substitute
female mortality table for the aggregation of Plans C, D, and E. However,
Employer F may not aggregate Plans C, D, and E and request to use one
substitute female mortality table for Plans C, D, and E, and three separate
substitute male mortality tables for Plans C, D, and E.

SECTION 6. IDENTIFICATION OF PLANS

.01 The following plan information must be provided for the Plan (or for each plan
within the Permissive Group) for which the use of substitute mortality tables is
requested:

(1) Plan name;

(2) Plan number;

(3) Plan year (i.e., calendar, or if fiscal, the first and last day);

(4) Employer identification number;

(5) Date of plan establishment; and

(6) Copies of the actuarial valuation reports for each plan year which begins
or ends during the Experience Study Period as defined in section 7.01 of
this revenue procedure.

.02 The following information must be provided for each plan that is subject to
§ 430 maintained by the applicant, or members of the applicant’s controlled
group, for which the use of substitute mortality tables is not requested:

(1) Plan name;

(2) Plan number;

(3) Plan year (i.e., calendar, or if fiscal, the first and last day);

8

(4) Employer identification number;

(5) Date of plan establishment;

(6) If the plan is newly acquired, the date of the merger, acquisition, or similar
transaction described in § 1.410(b)-2(f) of the regulations, and the date
described in § 410(b)(6)(C)(ii)(II); and

(7) The Lack of Credible Mortality Experience Demonstration Period, or, if the
plan is not required to identify such a period, the applicable exception.
(See section 9 of this revenue procedure.)

.03 The following additional information must be provided with respect to each
plan that is subject to § 430 that is maintained by the applicant, or member of
the applicant’s controlled group, that was spun off from another plan that is
maintained by the applicant within the five-year period preceding the date of
the request:

(1) The plan name and the plan number of the spun off plan, and the plan
name and number of the plan from which the spinoff occurred;

(2) The employer identification number of the employer maintaining the spun
off plan and the employer identification number of the employer
maintaining the plan from which the spinoff occurred;

(3) The date of the spinoff;

(4) The approximate number of individuals covered by the spun off plan as of
the date of the spinoff and the approximate number of individuals covered
by the plan from which the spinoff occurred, prior to the spinoff; and

(5) The reason for the spinoff.

SECTION 7. DEMONSTRATIONS OF CREDIBLE MORTALITY EXPERIENCE

.01 The applicant’s request must identify the period of time covered by the
mortality experience study (the “Experience Study Period”) used to develop
the Base Table(s) and must identify the Base Year. Different Experience
Study Periods for different populations within a plan are not permitted.
Except as provided in subsection .02 of this section, different Experience
Study Periods for different plans within the Permissive Group are not
permitted. Thus, a plan that does not have mortality experience for the entire
Experience Study Period may not be included in the Permissive Group.
Similarly, a plan that was acquired subsequent to the first day of the
Experience Study Period may be included in the Permissive Group only if the

9
applicant includes mortality experience for the full Experience Study Period.
Thus, in such cases, the mortality experience study must include mortality
experience that occurred before the date of acquisition.

.02 A plan that came into existence by reason of a spinoff from the Plan (or from
a plan within the Permissive Group) during the Experience Study Period may
be included in the Permissive Group. In such a case, the period of time
covered by the mortality experience study with respect to the spun off plan
will begin as of the date of the spinoff. However, the mortality experience of
the individuals covered by the spun off plan from the first day of the
Experience Study Period to the date of the spinoff would be included as part
of the experience of the single plan that existed before the spinoff.

.03 In order to demonstrate credible mortality experience, the number of deaths
during each year of the Experience Study Period (and, in total, for the entire
Experience Study Period) within each population for which the use of
substitute mortality tables is requested must be provided in tabular form.

SECTION 8. DEMONSTRATION OF STABILITY

.01 The following information must be provided in tabular form for each
population within the Plan (or plans within the Permissive Group) for which
the use of a substitute mortality table is requested, aggregating all plans that
have the same plan year:

(1) The average number of individuals within the population during the
Experience Study Period; and

(2) The number of individuals within the population as of the last day of the
plan year immediately preceding the plan year during which the use of
substitute mortality tables is requested.

A reasonable estimate of the number of plan individuals, such as the
estimated number of participants and beneficiaries used for purposes of
PBGC Form 1-ES, may be used to provide the information requested in
subsection .01(1) of this section.

.02 If the difference between (1) and (2) of subsection .01 of this section within
any population, for any plan year, reflects a difference of 20 percent or more,
then an analysis that shows that the mortality experience during the
Experience Study Period is still accurately predictive of the future mortality of
the population must be submitted.

SECTION 9. DEMONSTRATIONS OF LACK OF CREDIBLE MORTALITY
EXPERIENCE

10
.01 General Rule
. For all plans maintained by the applicant, except as described
in subsections .02 and .03 of this section, the 4-year period of time used to
demonstrate a lack of credible mortality experience must be identified (the
“Lack of Credible Mortality Experience Demonstration Period”).

.02 General Exception
. Plans described in paragraphs (1), (2), or (3) are not
required to identify a Lack of Credible Mortality Experience Demonstration
Period.

(1) Plans for which the use of substitute mortality tables is requested for all
populations (other than disabled populations for whom the tables
prescribed under § 430(h)(3)(D) are used);

(2) Plans for which the use of substitute mortality tables has previously been
approved by the Service and the term of years of such approval ends
subsequent to the last day of the Requested Effective Plan Year; and

(3) Newly acquired plans for which the last day of the period described in
§ 410(b)(6)(C) is a date on or after the first day of the plan year for which
the use of substitute mortality tables is requested.

.03 Exception for Certain Newly Acquired Plans
. Newly acquired plans (as
defined in § 1.430(h)(3)-2) for which the last day of the period described in
§ 410(b)(6)(C) is a date prior to the first day of the plan year for which the use
of substitute mortality tables is requested, and for which the applicant has
elected not to include mortality experience prior to the date of the acquisition,
may identify a Lack of Credible Mortality Experience Demonstration Period
less than 4 years in length. For such plans, the Lack of Credible Mortality
Experience Demonstration Period must begin no later than the date of
acquisition of the plan and end not more than one year and one day before
the first day of the plan year for which the use of substitute mortality tables is
requested.

.04 Demonstrations of Plan-Wide Lack of Credible Mortality Experience
. The
following information must be provided in tabular form for each plan that is not
within the Permissive Group and which does not fall within one of the
exceptions provided in subsection .02 of this section:

(1) The number of male deaths during the Lack of Credible Mortality
Experience Demonstration Period; and

(2) The number of female deaths during the Lack of Credible Mortality
Experience Demonstration Period.

.05 Demonstrations of Lack of Credible Mortality Experience for Certain
Populations. The number of deaths for the population during the Lack of

11
Credible Mortality Experience Demonstration Period must be provided in
tabular form for each relevant population within the Plan (or plans within the
Permissive Group) for which the use of substitute mortality tables is not
requested.

The relevant populations for this purpose would, for example, be nondisabled
females if the request was to use a substitute mortality table for nondisabled
males (but for no other individuals) where separate mortality tables were used
for disabled individuals pursuant to § 430(h)(3)(D). Similarly, the relevant
populations would be male non-annuitants and females, in each case
including disabled individuals, if the request was to use a substitute mortality
table for male annuitants (but not for male non-annuitants) where separate
mortality tables were not used for disabled individuals pursuant to
§ 430(h)(3)(D).

SECTION 10. UNADJUSTED MORTALITY EXPERIENCE

.01 In General
. The following information must be provided in tabular form for all
individuals within each population for whom the use of a separate mortality
table is requested, for each year of the Experience Study Period, and for the
Experience Study Period in its entirety, for all ages between 18 and 100
(except as provided in subsection .03 of this section):

(1) The sum of the accrued benefits (or payable benefits, in the case of
individuals in pay status) of all individuals at that age at the beginning of
the year, other than individuals who left the population during the year for
reasons other than death;

(2) The sum of the accrued (or payable) benefits of all individuals at that age
at the beginning of the year who left the population during the year for
reasons other than death, adjusted to reflect exposure periods of less than
one year;

(3) The sum of the accrued (or payable) benefits of all individuals at that age
at the beginning of the year who died during the year;

(4) The quotient determined by dividing the sum of the accrued (or payable)
benefits of all individuals at that age who died during the year by the sum
of the accrued (or payable) benefits for all individuals at that age adjusted
for individuals at that age who left the population for reasons other than
death (i.e., the amount determined in paragraph (3), divided by the total of
the amounts determined in paragraphs (1) and (2);

(5) The total number of individuals at that age at the beginning of the year;

12
(6) The total number of individuals at that age at the beginning of the year
who left the population for reasons other than death;

(7) The total number of individuals at that age at the beginning of the year
who died during the year; and

(8) The average accrued benefit of all individuals at that age at the beginning
of the year.

.02 Adjustment for Exposure Periods of Less than One Year
. The request must
include a description of the method(s) used to adjust the accrued benefits of
individuals who left for reasons other than death to reflect exposure periods of
less than one year.

.03 Grouping of Ages
. The information requested in subsection .01 of this section
may be presented in five-year age groups. In such cases, the groups at the
extreme ages may include more than five ages provided such groups either
do not include ages greater than age 24 or do not include ages less than age
95. Thus, for example, an age group consisting of all ages 24 and lower
would be permissible whereas an age group consisting of all ages 25 and
lower would not be permissible.

.04 Unadjusted Base Tables
. An Unadjusted Base Table for each population for
which the use of substitute mortality tables is requested shall, for all ages or
all groups of ages, consist of the quotients determined in paragraph (4) of
subsection .01 of this section for the Experience Study Period in its entirety.
The request must include a complete copy of each such Unadjusted Base
Table.

SECTION 11. BASE TABLE CONSTRUCTION – GENERAL METHOD

.01 In General
. Except as otherwise provided in Section 12 of this revenue
procedure, a Base Table for a population must be created from the
Unadjusted Base Table for the population through the application of a
graduation method generally used by the actuarial profession in the United
States (e.g., Whittaker-Henderson Type B, Karup-King). Section 12 of this
revenue procedure provides for an alternate method of constructing a Base
Table through the application of a fixed percentage to the mortality rates of a
Standard Mortality Table, projected to the Base Year.

.02 Information Regarding Graduation Methods
. The graduation method must be
identified and the parameters of the graduation method used must be
specified (e.g., for Whittaker-Henderson Type B, the number of differences
and the “h” value must be specified). If more than one graduation is
performed, then the parameters must be specified for each such graduation.

13
.03 Intermediate Values
. If more than one graduation is performed in the
process of adjusting an Unadjusted Base Table to a Base Table, then a copy
of each intermediate table so created must be provided.

.04 Rationale
. The rationale for the selection of each particular graduation
method used must be provided along with the rationale for the selection of the
particular parameters used as part of the method.

.05 Extension to Extreme Ages
. At extreme ages for which insufficient data
exists, the Base Tables must be extended to blend into the applicable
Standard Mortality Table, provided in subsection .06 of this section, projected
to the Base Year using Projection Scale AA, as set forth in the proposed
regulations. In such cases, the method (and the rationale for the method)
used for the extension must be described.

.06 Standard Mortality Tables
. For purposes of this revenue procedure, the
following are the Standard Mortality Tables:

(1) The Male Base Non-Annuitant Mortality Table (Year 2000) as set forth in
§ 1.430(h)(3)-1;

(2) The Male Base Annuitant Mortality Table (Year 2000) as set forth in
§ 1.430(h)(3)-1;

(3) The Female Base Non-Annuitant Mortality Table (Year 2000) as set forth
in § 1.430(h)(3)-1;

(4) The Female Base Annuitant Mortality Table (Year 2000) as set forth in
§ 1.430(h)(3)-1;

(5) The Male Base Combined Mortality Table (Year 2000) determined in
accordance with subsection .07 of this section; and

(6) The Female Base Combined Mortality Table (Year 2000) determined in
accordance with subsection .07 of this section.

.07 Gender-Specific Base (Year 2000) Mortality Combined Tables
. For
purposes of this revenue procedure, the Male Base Combined Mortality Table
(Year 2000) is the table determined through application of the male Weighting
Factors for Small Plans (the “Weights”) to the Male Base Non-Annuitant and
Annuitant Mortality Tables (Year 2000) as set forth in § 1.430(h)(3)-1.
Similarly, the Female Base Combined Mortality Table (Year 2000) is the table
determined through application of the female Weights to the Female Base
Non-Annuitant and Annuitant Mortality Tables (Year 2000) as set forth in
§ 1.430(h)(3)-1.

14
SECTION 12. BASE TABLE CONSTRUCTION – ALTERNATE METHOD

.01 General Rule
. A Base Table for a population may be created by applying a
fixed percentage (the “Fixed Percentage”) to the mortality rates in the
Projected Applicable Standard Mortality Table, only if the requirements of
subsections .02 and .03 of this section are satisfied and the Service
determines that the resulting Base Table sufficiently reflects the mortality
experience of the applicable plan population. For this purpose the Projected
Applicable Standard Mortality Table is the applicable Standard Mortality
Table, projected to the Base Year using Projection Scale AA, as set forth in
§ 1.430(h)(3)-1. See subsection .05 of this section with regard to the possible
use of other mortality tables for this purpose.

Under this section 12, the Unadjusted Base Mortality Tables must be
constructed using five-year age groups. For each Base Table constructed
using the alternate method described in this section, the Fixed Percentage
and the mortality table to which such percentage is to be applied must be
identified. In addition, for each so constructed Base Table, the ratios of the
mortality rates from the Unadjusted Base Mortality Table for the population to
the central age mortality rates (i.e., the mortality rates for the ages that are
the midpoints of the age ranges) from the Projected Applicable Standard
Mortality Table must be provided, in tabular form, for all five-year age groups
for which mortality experience is available.

.02 Selection of the Fixed Percentage
.

(1) If the applicable Standard Mortality Table for a population is the table
provided in either section 11.06(1) or section 11.06(3) of this revenue
procedure, then the Fixed Percentage must be within two percentage
points of the arithmetic average of the ratios of the mortality rates from the
Unadjusted Base Mortality Table for the population to the central age
mortality rates from the Projected Applicable Standard Mortality Table of
each of the five-year age groups from the 35-39 age group to the 60-64
age group, inclusive, unless the applicant can demonstrate that a different
set of five-year age groups (consisting of no less than six such groups) is
more appropriate for this purpose.

(2) If the applicable Standard Mortality Table for a population is the table
provided in either section 11.06(2) or section 11.06(4) of this revenue
procedure, then the Fixed Percentage must be within two percentage
points of the arithmetic average of the ratios of the mortality rates from the
Unadjusted Base Mortality Table for the population to the central age
mortality rates from the Projected Applicable Standard Mortality Table of
each of the five-year age groups from the 55-59 age group to the 80-84
age group, inclusive, unless the applicant can demonstrate that a different

15
set of five-year age groups (consisting of no less than six such groups) is
more appropriate for this purpose.

(3) If the applicable Standard Mortality Table for a population is the table
provided in either section 11.06(5) or section 11.06(6) of this revenue
procedure, then the Fixed Percentage must be within two percentage
points of the arithmetic average of the ratios of the mortality rates from the
Unadjusted Base Mortality Table for the population to the central age
mortality rates from the Projected Applicable Standard Mortality Table of
each of the five-year age groups from the 45-49 age group to the 80-84
age group, inclusive, unless the applicant can demonstrate that a different
set of five-year age groups (consisting of no less than eight such groups)
is more appropriate for this purpose.

.03 Consistency Requirement
. The consistency requirement of this subsection
.03 is satisfied only if each of the applicable ratios described in subsection .02
of this section is within 10 percentage points of the Fixed Percentage.

.04 Terminal Age. Notwithstanding subsection .01 of this section, the mortality
rate for the terminal age in any Base Table created by applying a Level
Percentage to a Standard Mortality Table shall be 1.000.

.05 Other Mortality Tables
. The Service will consider requests for the approval of
Base Tables constructed through the application of a fixed percentage to the
mortality rates of other published generally accepted mortality tables (e.g., the
1983 Group Annuity Mortality Table) using standards similar to those
provided in subsections .01 through .04 of this section.

.06 Example
. The age group rates from the Male Unadjusted Base Table
(determined in accordance with section 10 of this revenue procedure), the
central age rates from the Male Base Combined Mortality Table (Year 2000),
projected to the Base Year, and the ratios of such rates are as follows:

A B C

Age

(Year 2000)

45 to 49 0.00163 0.00165 98.79%
50 to 54 0.00211 0.00241 87.55%
55 to 59 0.00376 0.00431 87.24%
60 to 64 0.00765 0.00812 94.21%
65 to 69 0.01569 0.01506 104.18%
70 to 74 0.02439 0.02502 97.48%
75 to 79 0.03768 0.04387 85.89%

16
80 to 84 0.07948 0.07732 102.79%

Arithmetic Average Percentage 94.77%

In accordance with subsection .02 of this section, the Fixed Percentage to be
applied to the Male Base Mortality Table (Year 2000), projected to the Base
Year, must be between 92.77% and 96.77%. However, a Fixed Percentage
that is less than 94.18% would fail to satisfy the requirements of subsection
.03 of this section because the ratio for the 65-69 Age Group (i.e., 104.18%)
would then not be within 10 percentage points of a Fixed Percentage less
than 94.18%. Similarly, a Fixed Percentage that is greater than 95.89%
would fail the requirements of subsection .03 because the ratio for the 75-79
Age Group (i.e., 85.89%) would then not be within 10 percentage points of a
Fixed Percentage greater than 95.89%. Accordingly, under the facts in this
example, if the applicant were to request the use of a Base Table constructed
through the application of a percentage to the Male Base Mortality Table
(Year 2000) that is a fixed integer, the applicant would be limited to a Fixed
Percentage of 95%.

SECTION 13. DEMONSTRATIONS WITH RESPECT TO BASE TABLES

The following information must be provided with respect to each population for
which the use of substitute mortality tables is requested:

.01 Generational Mortality Tables
. Sample generational mortality tables, as of
the Requested Effective Plan Year, for individuals whose years of birth are
1940, 1950, and 1960, constructed from the Base Tables using methodology
in accordance with § 1.430(h)(3)-1 (except that the projection period used to
determine each particular mortality improvement factor is the number of years
between the Base Year and the year for which the probability of death is
determined).

.02 Funding Target Comparisons
. The liability of the plan(s) for which the use of
substitute mortality tables is requested as of the valuation date for a plan year
ending no earlier than one year and one day before the first plan year to
which the substitute mortality tables will apply (the “Comparison Year”). The
liability is to be measured using generational mortality tables determined in
accordance with the methodology described in subsection .01 of this section.
The liability is to be provided separately for active participants, terminated
vested participants, and retirees and beneficiaries in pay status, and is to be
determined as follows:

(1) For Comparison Years beginning in 2006, the liability to be reported is the
Current Liability recalculated using the mortality tables published in
§ 1.412(l)(7)-1 of the regulations, and, for comparison, what the Current
Liability would have been if the substitute mortality table(s) had been used

17
to determine Current Liability, in each case holding all other assumptions
constant.

(2) For Comparison Years beginning in 2007, the liability to be reported is the
Current Liability and, for comparison, what the Current Liability would have
been if the substitute mortality table(s) had been used to determine
Current Liability, holding all other assumptions constant.

(3) For Comparison Years beginning after 2007, the liability to be reported is
the Funding Target, determined without regard to at-risk assumptions
under § 430(i), and, for comparison, what the Funding Target would have
been if the substitute mortality table(s) had been used to determine the
Funding Target, holding all other assumptions constant.

.03 Annuity Factors
. The following annuity factors based on generational
mortality tables for individuals whose year of birth is 1950, determined using
interest and mortality assumptions consistent with those used under
subsection .02 of this section.

(1) For all Base Tables with the exception of annuitant Base Tables:

(a) Deferred to age 55 factors at quinquennial ages from 20 to 50; and

(b) Deferred to age 65 factors at quinquennial ages from 20 to 60.

(2) For all Base Tables with the exception of nonannuitant Base Tables,
immediate annuity factors at quinquennial ages from 50 to 90.

.04 Graphical Displays
. A comparison in the form of graphs with the X-axis
representing age and the Y-axis representing the mortality rate, for each of
the following pairs of mortality rates, for each population for which the use of
substitute mortality tables is requested:

(1) The mortality rates from the Base Unadjusted Mortality Table and the
mortality rates from the proposed Base Table; and

(2) The mortality rates from the proposed Base Table and from the applicable
Standard Mortality Table (as described in section 11.06 of this revenue
procedure), projected to the Base Year.

SECTION 14. EFFECTIVE DATE

This revenue procedure is effective for all requests for the use of plan-specific
substitute mortality tables in accordance with § 430(h)(3)(C) of the Code and
