Nortel Networks Corp., with headquarters in Bramptom, Canada, is a recognized leader in delivering communications capabilities that enhance the human experience, ignite and power global commerce, and secure and protect the world’s most critical information.

During 2004, Nortel operations were organized and represented by four operating segments which were also our reportable segments: Wireless Networks, Enterprise Networks, Wireline Networks, and Optical Networks. Effective October 1, 2004, Nortel established a new streamlined organizational structure that is comprised of the following operating segments: (a) Carrier Packet Networks, which is substantially an amalgamation of our previous Wireline Networks and Optical Networks operating segments; (b) Code Division Multiple Access, or CDMA, Networks, which previously represented a portion of the Wireless Networks operating segment; (c) Global System for Mobile communications, or GSM, and Universal Mobile Telecommunications Systems, or UMTS, Networks which also previously represented a portion of the Wireless Networks operating segment; and (d) Enterprise Networks, which remains substantially unchanged from the previous Enterprise Networks operating segment.
