No.333-8362) Nomura selects COLT as supplier of choice for Europe Japan's no.1 investment bank achieves superior communications at lower cost of ownership Nomura International, the European subsidiary of Japan's leading investment bank, has selected COLT as its preferred network supplier to deliver data and voice services to its employees across Europe. As a result of the deal, Nomura, whose financial services business relies on real-time and secure communications with clients and colleagues around the world, will benefit from significantly reduced supplier numbers and a more cost-effective offering, as well as a higher performance network, for its mission critical business applications. Ian Buchanan, Chief Information Officer (CIO) at Nomura International said: "At Nomura we pride ourselves on our pioneering sprit and our position at the forefront of our industry. As such, we constantly seek ways to improve our service delivery and efficiency. We believe that COLT's wholly owned, high performance network will help boost our pan-European operations. These kinds of enhancements to our network will ensure that the performance of our mission critical business applications is optimised. These factors, together with COLT's customer care record, make COLT an excellent selection as our European network partner." For data communications, COLT has connected Nomura's offices in eight countries - - the UK, Netherlands, Germany, France, Spain, Italy, Luxembourg and Switzerland - - with its market-leading managed Ethernet service, COLT LANLink Hub & Spoke*. This simple, secure and reliable high bandwidth service has enabled Nomura to connect its Local Area Networks (LANs) together, via Ethernet, the most widely used LAN technology, and seamlessly onward link to its global Wide Area Network (WAN) and thereby run its various sites as 'one office.' This will both reduce Nomura's IT costs and increase its efficiency. It has also enabled Nomura to deliver new services via the network, including IP video conferencing, which has led to improved performance, assisted business globalisation and achieved significant revenue savings. COLT is also providing Corporate Voice, a pan-European service which allows Nomura International to consolidate all of its voice expenditure under a single pricing structure and contract, thereby reducing its costs significantly. Tim Wort, managing director for COLT in the UK, commented: "Nomura International's decision to appoint COLT as its preferred network partner across Europe adds further endorsement to our position as a partner of choice for businesses with pan-European requirements. Leading financial institutions, such as Nomura, require increasingly high bandwidth and resilient networks to underpin their business. With our heritage in the financial sector and European footprint, COLT is committed to supporting the evolving requirements of the sector."
