Plan approved to use substitute mortality tables

Plain-English summary

A defined benefit pension plan asked to use substitute mortality tables when calculating its minimum funding obligations. The IRS approved the tables for male and female annuitants and nonannuitants, including disabled participants, after determining that the rates were developed under the applicable regulations and Revenue Procedure 2017-55. The approval requires generational application of the rates. It can end early if specified events occur, including certain coverage changes, loss of credible-data conditions, a finding that the tables are no longer predictive, or replacement of the standard mortality tables. The IRS did not express an opinion on the accuracy of the calculations or other submitted material.

Ruling snapshot

• Question: Could the plan use its proposed substitute mortality tables for minimum funding computations?
• Outcome: Approved for the male and female plan populations specified in the letter.
• Key authorities: IRC § 430(h)(3); Treas. Reg. §§ 1.430(h)(3)-1 and 1.430(h)(3)-2; Rev. Proc. 2017-55.

The above rates were developed based on an experience study period from
November 1, through October 31, for the Plan and Merging Plan 1, and an
experience study period from January 1, through December 31, for Merging
Plan 2 and Merging Plan 3. The base year of the experience period is . The rates
were calculated by adjusting the applicable standard mortality tables in
section 1.430(h)(3)-1(d) of the Regulations, using the mortality ratio and credibility
weighting factor determined by aggregating male and female experience, as shown in
the table below.

Male and Female,
Annuitants and Nonannuitants,
Including Disabled Participants

Mortality ratio

Credibility Weighting Factor

The Internal Revenue Service (“IRS”) has reviewed the substitute mortality rates and
supporting information, and has determined that based on the information submitted,
the rates were developed in accordance with section 1.430(h)(3)-2 of the Regulations
and Revenue Procedure 2017-55.

The above rates must be applied on a generational basis, as provided in
section 1.430(h)(3)-2(c)(3) of the Regulations.

Your attention is called to section 430(h)(3)(C)(ii) of the Code and
section 1.430(h)(3)-2(d)(6) of the Regulations, which describe the circumstances in
which the use of the substitute mortality table will terminate before the end of the -year
period described above. In general, the substitute mortality tables can no longer be
used as of the earliest of:

(1) For a plan using a substitute mortality table for only one gender, the first plan
year for which there is full or partial credible mortality information with respect to
the other gender that had lacked credible mortality information (unless an
approved substitute mortality table is used for that gender),

(2) The first plan year in which the plan fails to satisfy the requirements of
section 1.430(h)(3)-2(c)(1) of the Regulations, regarding the requirement that
other plans and populations in the controlled group must also use substitute
mortality tables unless it can be demonstrated that they do not have credible
mortality information (taking into account the transition period for newly affiliated
companies in section 1.430(h)(3)-2(f)(3) of the Regulations),

(3) The second plan year following the plan year for which there is a significant
change in individuals covered by the plan as described in
section 1.430(h)(3)-2(c)(6)(iii) of the Regulations,

(4) The plan year following the plan year in which a substitute mortality table used
for a plan population is no longer accurately predictive of future mortality of that
population, as determined by the Commissioner or as certified by the Plan’s
actuary to the satisfaction of the Commissioner, or

(5) The date specified in guidance published in the Internal Revenue Bulletin
pursuant to a replacement of mortality tables specified under
section 430(h)(3)(A) of the Code and section 1.430(h)(3)-1 of the Regulations,
other than annual updates to the static mortality tables issued pursuant to
section 1.430(h)(3)-1(a)(3) of the Regulations or changes to the mortality
improvement rates pursuant to section 1.430(h)(3)-1(a)(2)(i)(C) of the
Regulations.

In particular, section 1.430(h)(3)-2(c)(6)(iii) of the Regulations provides that the use of
substitute mortality tables must be discontinued after a significant change in coverage
unless the plan’s actuary certifies in writing to the satisfaction of the Commissioner that
the substitute mortality tables used for the population continue to be accurately
predictive of future mortality of the population (taking into account the effect of the
change in the population). For this purpose, a significant change in coverage occurs if
the number of individuals covered by the substitute mortality table for a plan year is less
than 80 percent or more than 120 percent of either (1) the average number of
individuals in that population over the years covered by the experience study on which
the substitute mortality table is based, or (2) the number of individuals covered by the
substitute mortality table in a plan year for which a certification described in
section 1.430(h)(3)-2(6)(c)(iii)(A) of the Regulations was made.

This ruling is directed only to the taxpayer that requested it. Section 6110(k)(3) of the
Code provides that it may not be used or cited by others as precedent.

When filing Form 5500 for the plan years for which the substitute mortality tables are
used, please note the information that is required to be attached to Schedule SB
(Actuarial Information) in accordance with the instructions to that form.

We have sent a copy of this letter to your authorized representatives pursuant to a
power of attorney on file in this office and to the Manager, EP Classification in
Columbus, Ohio and to the Manager, EP Compliance Unit in Chicago, Illinois.

If you require further assistance in this matter, please contact
