(1) the Group A primary party:

(A) had at least 20 years of pension service, left active service after October 1, 1985, and was at least 55 years of age on the earlier of the date the primary party:

(i) left active service; or

(2) the spouse has attained 55 years of age and there are no children who are qualified survivors eligible for death benefits.

(b) Until the requirements of Subsection (a) of this section are satisfied, a qualified survivor who is the spouse of a Group A primary party shall receive a Group A death benefit in accordance with Section 6.07 of this article.

(c) The special Group A death benefit under Subsection (a) of this section is calculated based on the following formula:

(P x P x A) + (P x C) + D, where

B = Group A primary party's benefit calculated at the time the Group A primary party began participation in DROP, begins service retirement, dies, or becomes disabled;

P = B/A (expressed as a percentage or a decimal);

C = the number of adjustments made to a Group A primary party's retirement pension, disability pension, or periodic disability compensation, multiplied by the amount of the adjustments; and

D = the number of adjustments made under this article to the Group A death benefit of a spouse who is a qualified survivor under Section 6.07 of this article, multiplied by the amount of the adjustments.

(d) A person who is the spouse of a Group B primary party, who is a qualified survivor, and who is entitled to any death benefits under Sections 6.06, 6.061, 6.062, 6.063, and 6.08 of this article is also entitled to a special benefit under this section if:

(2) the spouse has attained 55 years of age, and there are no children of the primary party who are qualified survivors.

A = average monthly computation pay at the time the Group B primary party begins service retirement, dies, becomes disabled, or begins participation in DROP;

B = the Group B primary party's benefit calculated at the time the Group B primary party begins participation in DROP, begins to receive service retirement, dies, or becomes disabled;

P = B/A (expressed as a percentage or a decimal);

C = the number of post-retirement adjustments made to a Group B primary party's retirement pension, disability pension, or periodic disability compensation multiplied by the amount of the adjustments; and

D = the number of adjustments made to the Group B death benefit of a qualified survivor who is the primary party's spouse under Section 6.08 of this article multiplied by the amount of the adjustments.
