12 Appendix A: Operating Information Footnotes (cont.) 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 verification by MasterCard and partial cross-checking against information provided by MasterCard’s transaction processing systems. The data set forth in the accounts, cards and acceptance locations columns is derived from information provided by MasterCard members and is subject to certain limited verification by MasterCard. Certain information with respect to acceptance locations is provided by third parties and has not been independently verified by MasterCard. All data is subject to revision and amendment by MasterCard’s members subsequent to the date of its release. Volumes for the periods indicated in the following tables for MasterCard-branded debit programs in the U.S. region and credit programs in the Asia/Pacific region are higher due to expanded data collection of PIN point of sale volumes. Prior periods have been adjusted to ensure comparability. 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 significant revenues. Note that the columns in the tables may not add due to rounding. Growth represents change from the comparable year-ago period. |
