You'd have to go back to the MN1 interviews if they are still available. I wish now I paid more attention, but I think he mentioned something about using a trust to do that with.
This is a relatively new tactic to protect shareholders but I believe this has been part of Mr. Harris' plan all along...
"I am not a conspiracy theorist; however securities sold short in US public markets that haven't got a prayer of being delivered to the buyer are essentially trapped capital that, under the correct circumstances and conditions, could translate into involuntary buying power. It is now widely believed that a grandfathered strategic Failure to Deliver ('FTD') exists in the US capital markets ushered in by the SEC in Jan 2005. Private research and public allegations are emerging that decades of electronic erosion isn't just a bunch of sporadic market makers and their customers performing isolated hedging in response to sudden buying or selling bursts. As many have witnessed, the benevolent act of making a market can turn ugly when a Market Maker (s) and its customer (s) activity shifts from making a fair market to flouting its privileges. The Market Maker and its customers employing strategic FTD's as a trading strategy do so risking the full burden of being caught short, because securities can only fall to zero, they can also rise to infinity, this altruistic act of transferred risk presumably represents Captured Capital. Certainly being caught short is what was on the SEC's mind by allowing a hall pass to the decades of strategic FTD's that were established pre Regulation SHO. When will the investing public know the extent and scope of the 'grandfathered position?' The consensus of this gathering is that the grandfathered FTD's are possibly a brobdingnagian of Captured Capital."
