# §228.10. Computation of the tier I annuity component for a widow(er), disabled widow(er), remarried widow(er), and a surviving divorced spouse.


The tier I annuity component for these beneficiaries is generally based on the survivor tier I Primary Insurance Amount (PIA). The survivor tier I PIA is determined in accordance with section 215 of the Social Security Act using the deceased employee's combined railroad and social security earnings after 1950 (or after 1936 if a higher PIA would result) up to the maximum creditable amounts through the year of the employee's death. See [part 225](/cfr/20/part225.md) of this chapter. This amount may be further adjusted for certain reductions or deductions as described in [§§ 228.15-228.20](/cfr/20/228.15-228.20.md) of this part and is subject to the family maximum. See [§ 228.14](/cfr/20/228.14.md) of this part.
