Nasdaq is a pioneer in electronic trading. We believe that we have the fastest, most efficient trading platform for equities in the U.S., with almost 100% system reliability and high scalability. Similarly, OMX has extensive experience and expertise in providing state-of-the art exchange technology worldwide to a sophisticated and global customer base, and is well-known for its innovative technology development. PHLXs proprietary trading system has demonstrated superior capacity, speed and system reliability within the U.S. derivatives market. This combination unites world class technology leadership across all of our product offerings and, over time, we expect to integrate these technologies into a best-of-breed platform that we believe will enable us to further enhance our competitive position.
