In a 2008 settlement with social networking titan Facebook, Tyler and Cameron Winklevoss garnered a windfall now estimated at more than $140 million over charges that founder Mark Zuckerberg
(pictured) stole their idea. But now they want to undo that settlement, claiming they are owed more – perhaps $500 million,
The New York Times reports .
The settlement amounted to $20 million in cash and $45 million in Facebook shares – the company is still privately held. The shares have more than tripled in value on private exchanges since then. But the Olympic-rowing twins say they should have received more, because Zuckerberg and Facebook deceived them about the shares’ true value.
Next month, the Winklevoss’ plan to ask a federal appeals court in San Francisco to dump the deal so they can pursue their original case and obtain a bigger payout. The risk is they may end up with nothing.
