lifegear: For the purposes of my answer, let's assume that somehow RA, Gunderson, and USXP somehow come up with the full amount. If they do, somewhat over 9M of the USPX penalties and some of the RA and Gunderson penalties (though I don't know how much), is earmarked to go to shareholders.
That said, how much of that will actually make it to shareholders is a big question, and it would all be earmarked to go to shareholders who owned the shares during the period of time covered by the SEC suit. Nobody who bought any shares after the SEC filed suit would be covered for any losses on those shares.
