The last paperwork showing on the SEC site is a Form DEF 14C - filed on 10/31 - perhaps the new Form will show up later in the day.

It appears PO may have bought the additional 250,000 Class A shares that BG owned, except the field that indicates 'Amount of Securities Beneficially Owned Following Reported Transaction' (my emphasis) is just 250,000.  If he had bought BG's shares it should be 500,000.

So not sure exactly what the Form indicates.  And why that Form?  I don't see a Form 4 filed with the SEC anywhere recently.
