New research by Towers Watson shows that defined benefit plans achieved better rates of return than defined contribution plans in 2008 by the widest margin since the early 2000s. However, in 2009, DC plans outperformed DB plans.
By analyzing financial data filed to the Department of Labor, analysts found that DB plans had median investment returns of -23.44% in 2008, while DC plans had median returns of -26.12%. This means that DB plans outperformed DC plans by roughly 2.7 percentage points.
