Despite the fact that the number of restatements companies issue are on the rise, investors are suing less. The New York Times reports that last year there were about 1,200 such financial restatements, but only five class actions filed. Stanford University Professor Joseph Grundfest, noting that investors losses are also way down, credits the trend to the fact that the big lawsuits of the market bubble bursting in 2000 are mostly history. "The pig may have moved through the python," Grundfest told The Times. He added that today's restatements reflects greater care on the part of the companies than the possibility that the company has engaged in fraudulent behavior. But other observers say the drop in lawsuits may be the result of increased use of the Private Securities Litigation Reform Act of 1995, which makes it easier for companies to get suits dismissed, especially those aimed at top corporate executives.
