      Maestro(R) and Cirrus(R) on-line debit transactions, Mondex(R)
transactions and other branded transactions are not included in the preceding
tables.

      For purposes of the tables: GDV represents purchase volume plus cash
volume and includes the impact of balance transfers and convenience checks;
purchase volume means the aggregate dollar amount of purchases made with
MasterCard-branded cards for the relevant period; and cash volume means the
aggregate dollar amount of cash disbursements obtained with MasterCard-branded
cards for the relevant period. The number of cards includes virtual cards, which
are MasterCard-branded payment accounts in connection with which functional
cards are not generally issued.

      The MasterCard payment product is comprised of both credit programs and
off-line debit programs, and certain data relating to each type of program is
included in the tables. Credit programs include MasterCard-branded credit and
charge programs. Off-line debit programs include MasterCard-branded debit
programs where the primary means of cardholder validation at the point of sale
is for cardholders to sign a sales receipt.

      Information denominated in U.S. dollars is calculated by applying an
established U.S. dollar/local currency exchange rate for each local currency in
which MasterCard volumes are reported. These exchange rates are calculated on a
quarterly basis using the average exchange rate for each quarter. However,
MasterCard reports period-over-period rates of change in GDV, purchase volume
and cash volume solely on the basis of local currency information, in order to
eliminate the impact of changes in the value of foreign currencies against the
U.S. dollar in calculating such rates of change. Accordingly, the
period-over-period rates of change set forth in the tables cannot be
extrapolated directly by reference to dollar volume information presented by
MasterCard for the current and historical periods.

      The data set forth in the GDV, purchase volume, purchase transactions,
cash volume and cash transactions columns is derived from information provided
by MasterCard members that is subject to logical and statistical verification by
MasterCard and partial cross-checking against information provided by
MasterCard's transaction processing systems. The data set forth in the accounts
and cards columns is derived from information provided by MasterCard members and
is subject to certain limited logical and statistical verification by
MasterCard. All data is subject to revision and amendment by MasterCard's
members subsequent to the date of its release.

      A portion of the data set forth in the accounts and cards columns reflects
the impact of routine portfolio changes among members and other practices that
may lead to over counting of the underlying data in certain circumstances.

      The tables include information with respect to MasterCard-branded
transactions that are not processed by MasterCard and transactions for which
MasterCard does not earn revenues.

      Certain information in the preceding tables has been the subject of prior
public release by MasterCard. The information in the preceding tables for the
years ended December 31, 2003 and 2002 has been restated to conform to the
presentation of information in the tables for the three months ended March 31,
2004 and to reflect revisions to certain historical statistical information
provided by MasterCard's members subsequent to the previous release of this
information by MasterCard. Among other adjustments, the number of cards has been
adjusted for all periods to reflect a change in reporting methodology by a U.S.
member.

      Attached also as Exhibit 99.1 is a press release issued by MasterCard
International Incorporated, dated May 3, 2004, which further discusses the
results of MasterCard's payment programs for the three months ended March 31,
2004.
