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.","path":["Title 20—Employees' Benefits","CHAPTER II—RAILROAD RETIREMENT BOARD","SUBCHAPTER B—REGULATIONS UNDER THE RAILROAD RETIREMENT ACT","PART 225—PRIMARY INSURANCE AMOUNT DETERMINATIONS","Subpart C—PIA's Used in Computing Survivor Annuities and the Amount of the Residual Lump-Sum Payable"],"source_url":"https://www.ecfr.gov/api/versioner/v1/full/2026-08-25/title-20.xml","current_through":"2026-08-25","vintage":"","retrieved_at":"2026-08-27T02:24:45Z","sha256":"01483d0ae870ab71cac35671189ff2eb0e844c01f1014122047dace885917a8f","source_id":"us-cfr","stale":true,"prev":"us/20-cfr-225.15","next":"us/20-cfr-225.21"},"notice":"GroundRules: Original legal text.
