Link to filing for 2010, the last year of multiple "whale" holdings of CRYFQ: http://www.sec.gov/Archives/edgar/data/912500/000130409611000016/crystallex13ga.htm

Appears 13G numbers are same for 2011 and 2012. Keep in mind, these guys do trade. Likely using a computer program. The filing is specifically for Dec 31, of whatever year, and is no indication of what went on during the rest of the year.

I strongly encourage personal review to verify the Greywolf filings. Also, perform personal DD to verify anything heard about Crystallex, as well as any other stock invested in. Always - Trust, but Verify.
