DI 52150.085 Chart of Triennial Redetermination Ratios

Redetermination (redet) ratios based on offset effective dates (OEDs) 1966 through 2001 are in the chart below. (For more information about the OED, see DI 52150.020 WC/PDB Offset First Considered (OFC) Date and Offset Effective Date (OED).) The chart below provides ratios in 3-decimal-place format for redet years 1969-2003 and 5-decimal-place format for redet year 2004.

  • •

    Redetermination (redet) ratios effective January 2005, and continuing (e.g., based on OEDs beginning 2002), are not displayed in the chart below but can be found at the Office of the Actuary (OACT) website at: http://www.ssa.gov/OACT/aceredet/index.html . This website lists all redet ratios beginning with the redet year 1979 (based on an Offset Effective Date of 1976).

  • •

    All redet ratios on the OACT website are shown in 5-decimal-place format. However, the Interactive Computation Facility (ICF) for Workers’ Compensation/Public Disability Benefits (WC/PDB) computes redet calculations prior to January 2004 using the 3-decimal-place ratio and redet calculations for January 2004 or later using the 5-decimal-place ratio. Use these same rules when manually computing redets.
