pg 37 of KADR 10q for dec 31 2011:
"JANA and Vicis own approximately 13% and 12% of the Company’s outstanding common stock, respectively. The debt agreements with JANA, Vicis and LSP Partners require the lenders’ consent for debt transactions which are senior or pari passu to the debt due them. Additionally, the lenders also require consent for equity transactions."
Jana has not sold anything since dec 31 2011 therefore they have 13% x 193 outstanding shares = 25.09 mill shares
Vicis sold some so they own like 19 mill as of the 2nd week in feb and there havent been any filings since.
I wouldnt necessarily trust randomn websites once companies go "in the dark" that is why you have to rely on reading the 10q. That has to be accurate in terms of who holds what. They can't lie in a SEC filing.
