The assets in question are currently being reported as worth $40 million. They include bank accounts in Hong Kong and New Zealand, Dotcom's mansion home, luxury cars, jet skis, big-screen TVs, a $10,000 watch and an Olaf Mueller photograph said to be worth more than $100,000, according to Ars Technica. The reasoning behind the seizure is that Dotcom is a fugitive — he's never appeared in American court and therefore cannot claim the assets the US government kept.

Of course, Dotcom's legal team says otherwise, even though their appeals have thus far been unsuccessful. "Kim Dotcom has never been to the United States, is presumed innocent, and is lawfully opposing extradition under the United States-New Zealand Treaty—yet the United States by merely labeling him as a fugitive gets a judgement to take all of his assets with no due process," Dotcom's lawyer Ira Rothken told Ars Technica. The defense now places its hopes at the feet of the New Zealand and Hong Kong Courts, said Rothken, who have the legal authority over the assets.
