Having owned several stocks during the dot com era, I regularly get notices about security litigation. Sometimes I bother to fill them in. And, even more rarely, do I actually receive a check!
Here's my share of the distribution from a settlement against AOL / Time Warner.
Some stats: I get $180.69 from a theoretical distribution of: $2.39B. About 750,000 claims were filed. I think the laywers got most of the money, and Time Warner paid the SEC about $300M, from whence the checks have been drawn.
The wages of evil baby!
