Talk of Facebook listing after the firm adopts dual stock structure

FACEBOOK has introduced a dual-class stock structure to let existing shareholders maintain voting control.<br /><br />The decision has been interpreted by some analysts as a signal that the company is planning to go public, a claim denied by the social networking site&rsquo;s chiefs last night.<br /><br />Facebook said: &ldquo;We did introduce a dual-class stock structure because existing shareholders wanted to maintain control over voting on certain issues to help ensure the company can continue to focus on the long term.&rdquo;<br /><br />However, Facebook founder Mark Zuckerberg admitted in May that he expected the company to eventually go public. Google implemented a dual-class stock structure before going public in 2004.
