What is ticker symbol for station casinos?

Harrahs doesn't have a ticker symbol any more because it was bought out by affiliates of private-equity firms TPG Capital and Apollo Global Management on January 28, 2008. (Source: http://investor.harrahs.com/phoenix.zhtml?c=84772&p=irol-homeProfile&t=&id=&)

So what other ticker symbol harrah's used to trade their stock?

Are you telling me that they are not in the stock exchange any more? thanks
