The expected post-Morrison decline in federal securities class-action filings hasn’t yet materialized. Thanks to a second half jolt, the pace of U.S. filings is on track to exceed last year’s total, according to the latest study by NERA Economic Consulting.

Following a slowdown during the first half of the year, NERA projects federal securities class-action filings will reach 239 cases by year’s end, well above the 220 class-action cases filed in 2009, according to the firm’s 2010 Year-End Update. The report is based on filings and dismissals through Nov. 30 and settlements through Dec. 31.
