Standard mortality table
(iii) Standard mortality table(A) Projection of base table. Except as otherwise provided in this paragraph (d)(4)(iii), the standard mortality table for a year is the mortality table determined by applying cumulative mortality improvement factors determined under 1.430(h)(3)-1(b)(2)(ii) to the base mortality table under 1.430(h)(3)-1(d) for the period beginning with the base year for that mortality table and ending in the base year for the base substitute mortality table determined under paragraph (c)(3)(ii) of this section. For purposes of the preceding sentence, the cumulative mortality improvement factors are determined using the mortality improvement rates described in 1.430(h)(3)-1(b)(1)(iii) that apply for the calendar year during which the plan sponsor submits the request for approval to use substitute mortality tables.
