CEM has been collecting data on DB and DC plans since 1991 and 1997, respectively. As calculated in our 2006 study, DB funds outperformed DC plans from 1998‐2005, by 1.80% (Flynn and Hubert, 20061 ). A return difference that in 25 years would result in a 34% smaller account value for the DC participant compared to the account value of the DB participant that started with the same dollar amount. However, in the last ten years, this margin has decreased considerably. This paper discusses why.
