Newsday has a rare article about one of the key components of class action settlements: the claims administrator.  The article begins by noting that

At Melville-based GCG Inc. [formerly called Garden City Group], corporate scandals can be good business.

The company is one of the largest administrators of class-action lawsuits, with about half of its business coming from securities litigation, said GCG president David Isaac.

Indeed, according to the SCAS database, as of the beginning of the 4th quarter of 2005, GCG had served as a claims administrator in no fewer than five of the top ten securities class actions since the passage of the Reform Act (WorldCom, Enron, Lucent, Dynegy and Global Crossing).

The article states that although GCG hasn't released financial figures for 2005, 2004 revenue was $86.4 million in 2004, a 15.9 percent jump from 2003. 

The article also adds that according to the Administrative Office of the U.S. Courts, the number of class action lawsuits filed in federal courts reached 2,693 in 2004.  As there were approximately 213 separate federal securities class actions filed in 2004, this means that at least 8% of all class actions filed were securities cases.  However, most of these 213 securities actions saw multiple and sometimes dozens of securities class action complaints filed, which were later consolidated into one case.  It is unclear whether these "multiple lawsuit" cases are counted separately or as one case by the Administrative Office.
