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 a 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 2007, the liability to be reported is the Current Liability determined in accordance with § 412(l) as it existed prior to PPA ’06 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.

(2) 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 20 years before the Base Year, 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, deferred to age 55 factors at quinquennial ages from 20 to 50.
