The 100 largest U.S. public pension funds reaped $73.2 billion from investment earnings in the first quarter of 2014, according to a report from the U.S. Census Bureau’s Quarterly Survey of Public Pensions.

The funds had a combined $3.218 trillion in cash and securities as of March 31, up 9.4% higher from a year ago. That’s the highest asset total for the public plans since the survey was first conducted in 1968. The top 100 funds account for 89.4% of U.S. public pension fund assets.
