# §225.26. Residual Lump-Sum PIA.


The Residual Lump-Sum PIA (RLS PIA) is used to compute the regular retirement annuity amounts to be deducted from the gross residual lump-sum amount in determining the amount of the residual lump-sum payable, as explained in [part 234](/cfr/20/part234.md) of this chapter. The RLS PIA is determined in accordance with section 215 of the Social Security Act using the employee's railroad compensation after 1950 (or after 1936, if a higher PIA would result) as if it were social security earnings. The RLS PIA is computed just like the retirement Tier I PIA described in [subpart B](/cfr/20/subpartB.md) of this part, except that social security earnings are not used to compute the RLS PIA.
