[Code of Federal Regulations] [Title 20, Volume 1] [Revised as of April 1, 2005] From the U.S. Government Printing Office via GPO Access [CITE: 20CFR225.24] [Page 449] TITLE 20--EMPLOYEES' BENEFITS CHAPTER II--RAILROAD RETIREMENT BOARD PART 225_PRIMARY INSURANCE AMOUNT DETERMINATIONS--Table of Contents Subpart C_PIA's Used in Computing Survivor Annuities and the Amount of the Residual Lump-Sum Payable Sec. 225.24 SS Earnings PIA used in survivor annuities. The Social Security Earnings PIA (SS Earnings PIA) used in survivor annuities may be used in computing the tier II component when the survivor tier II is based on a percentage of the employee annuity tier II and the employee had been or would be, if he or she were still alive, entitled to a vested dual benefit. If the employee received a retirement annuity before death, this PIA is identical to the retirement SS Earnings Dual Benefit PIA described in subpart B of this part. If a retirement annuity was not paid before the employee's death, the PIA is determined as if the employee were 65 years old in the month of his or her death. The SS Earnings PIA used in survivor annuities is determined in accordance with section 215 of the Social Security Act as in effect on December 31, 1974. It is computed using the deceased employee's social security earnings after 1950 (or after 1936, if a higher PIA would result) through December 31, 1974.
