What is a Global Security? Unless otherwise noted in the applicable prospectus or pricing supplement, we will issue each security in book-entry form only. Each security issued in book-entry form will be represented by a global security that we deposit with and register in the name of one or more financial institutions or clearing systems, or their nominees, which we select. A financial institution or clearing system that we select for any security for this purpose is called the “depositary” for that security. A security will usually have only one depositary but it may have more. Each series of securities will have one or more of the following as the depositaries:

| • |     | The Depository Trust Company, New York, New York, which is known as “DTC”; |

| • |     | Euroclear System, which is known as “Euroclear”; |

39

| • |     | Clearstream Banking, société anonyme, Luxembourg, which is known as “Clearstream”; 
 and                                                                                |

| • |     | any other clearing system or financial institution named in the applicable prospectus supplement. |

The depositaries named above may also be participants in one another’s systems. Thus, for example, if DTC is the depositary for a global security, investors may hold beneficial interests in that security through Euroclear or Clearstream, as DTC participants. The depositary or depositaries for your securities will be named in your prospectus supplement; if none is named, the depositary will be DTC. A global security may represent one or any other number of individual securities. Generally, all securities represented by the same global security will have the same terms. We may, however, issue a global security that represents multiple securities of the same kind, such as debt securities, that have different terms and are issued at different times. We call this kind of global security a master global security. Your prospectus supplement
