yeh, I noticed the same, abit different (ie DATE OF ACQUISITION: N/A UNKNOWN TO CITI & CONSIDERATION:N/A UNKNOWN TO CITI.) 60M shares with value atm of $3.3M. A transfer or sale to citigroup on 12/10 but no details about where from, nothing on citi group site either, probably linked to convertible notes imo.
Have all convertible notes been converted now?
