Code of Federal Regulations Title 20. Employees' Benefits § 20.225.20 General

The Survivor Tier I PIA and the Employee RIB PIA are used in computing the tier I component of a survivor annuity. The Combined Earnings PIA, Social Security Earnings PIA and Railroad Earnings PIA may be used in computing a vested dual benefit offset in the survivor tier II component when the survivor tier II is based on a percentage of the employee annuity tier II. In addition, these three PIA's are identical to those dual benefit PIA's used in computing an employee retirement annuity, as described in subpart B of this part, when the employee died after being entitled to an annuity. Survivor annuity computations are discussed in part 228 of this chapter. The Residual Lump–Sum PIA (RLS PIA) is used in computing the amount of the residual lump-sum payable when retirement annuity payments were made, as explained in part 234 of this chapter.
