Assets of the 200 largest defined contribution plans grew to 15.4% of U.S. gross domestic product from slightly less than 11.5% five years earlier, while defined benefit assets rose about 3% over that same period to 30.5%.
The 200 largest DC plans had about $2.9 trillion in assets as measured by Pensions & Investments as of Sept. 30, while assets of the largest 200 DB plans stood at about $5.7 trillion. Despite the size difference, the compound-annual growth rate of the DC assets was 8.6% since 2013, about double that of the largest DB plans.
