From the discloser statement, it clearly notes the float as of 3-1-2006 was 361,892,600, and the OS at 811,500,100.
As of 1-1-2007 it shows the float being unavailable and the OS being 780,886,530.
More current it shows period end of 12-31-2007 the float being 362,238,866, noted being from the shareholder list dated 8-20-2007 and the OS being 816,156,800.
So that means in about 1 1/2 years the float had not increased like so many were saying. Being from 3/2006 to 8/2007 it increased like 400,000 in total.
These numbers are from page 12 in the discloser. Thank you for the correction, I did speak a little to freely.
Now as of 2008, the os and float may have or may have not increased. I assume if Drake keeps up the filings we will find out how much.
