This excerpt taken from the C DEF 14A filed Mar 20, 2009.
Does any single stockholder control as much as 5% of any class of Citis voting stock?
Yes, according to a Schedule 13 G Information Statement filed by State Street Bank and Trust Company on February 17, 2009, State Street may be deemed to beneficially own 6.2% of Citis common stock. State Street, the custodian for Citis 401(k) Plan, disclaimed beneficial ownership of all such shares in the Information Statement.
In 2008 and 2009, Citi issued to the U.S. Treasury warrants to purchase 465,117,176 shares of common stock, of which warrants to purchase 360,075,159 shares of common stock are exercisable within 60 days. The exercise prices for the warrants are $10.61 and $17.85. The warrants exercisable within 60 days represent approximately 6.2% of Citis voting stock. However, none of the warrants have been exercised and the exercise prices are above Citis closing price on March 6 of $1.03. See Citis Annual Report on Form 10-K filed on February 27, 2009 for additional information.
