In connection with the securities offered hereby, each issuer will pay "pay-as-you-go registration fees" in accordance with Rule 456(b) under the Securities Act, except with respect to the offset pursuant to Rule 457(p) as described in footnotes 1 and 2 to Table 2 below. Includes an unspecified number of securities that may be offered or sold by direct or indirect subsidiaries of the issuers in market-making transactions. These securities consist of an indeterminate amount of such securities that are initially being registered, and will initially be offered and sold, under this Registration Statement and an indeterminate number or amount of such securities that were initially registered, and were initially offered and sold, under registration statements previously filed by Citigroup Inc., its corporate predecessors, Citigroup Global Markets Holdings Inc., or the Additional Registrant. All such market-making transactions with respect to these securities that are made pursuant to a registration statement after the effectiveness of this Registration Statement are being made solely pursuant to this Registration Statement.
