Could Lump-Sums for Grandfathered Southern California Edison employees be on the decline? The September interest rates, which Southern California Edison uses to determine lump sum values for everyone who retires in 2022 were released in October. We now have new monthly segment rates which show that interest rates are continuing to rise. Rates have been steadily increasing over the past year and with the recent announcement of next year's interest rates we are very likely to see a reduction in lump-sum values for Southern California Edison employees who retire in 2023. Southern California Edison interest rates decreased in 2020 causing 2021 lump sums to hit record highs. Based on the current trend of interest rates and monetary policy announcements it is likely that rates seen in 2020 will be the lowest for the foreseeable future - meaning that the Lump Sum Values for Southern California Edison employees who retired in 2021 will likely be the highest for the foreseeable future. When interest rates move up or down, your pension lump sum amount will move in an inverse relationship.
