THE BLAME: Facebook is suggesting that trading problems at the Nasdaq Stock Market contributed to a sharp drop in the company's stock price after its initial public offering.
THE DEFENSE: Facebook and the banks overseeing the IPO, which face lawsuits from disgruntled shareholders, insist that nothing about its IPO process was illegal or even out of the ordinary.
THE PROCEDURES: Facebook and the banks are seeking to combine the more than 40 federal and state lawsuits around the country into one federal case in New York.
