Ameritrade is working closely with the NASD to resolve the issue and expects to discuss it more with investors after the merger's expected close, Ameritrade spokeswoman Donna Kush said. "We're still discussing with (the NASD) how to handle this," Kush said. More than 99 percent of the votes cast by Ameritrade stockholders were in favor of the merger, the company said in a statement. The votes were cast by proxy and at a special stockholders meeting in Omaha, Neb. Under the merger agreement, Datek stockholders will own about half of the total shares of the combined company. Separately on Tuesday, Ameritrade announced eight of the nine board members of the combined company. J. Joe Ricketts, the founder and chairman of Ameritrade, will serve as chairman of the combined company.
