NYSE Euronext and Bloomberg Bring Open Symbology to Data Feeds
-Industry Leaders Join Forces to Promote Transparency and Lower Data Management Costs-

New York , March 18, 2010 – In a new initiative to promote transparency and lower data management costs for financial market participants, NYSE Euronext (NYX) and Bloomberg Finance L.P. (Bloomberg) today announced that they will deliver to the investing public the market data industry’s first open-source security identifiers.  Beginning next month, NYSE Euronext will distribute Bloomberg Open Symbology (BSYM) along with NYSE Euronext's standard security identifiers for New York Stock Exchange listed companies through all of its data products globally.   

Combining Bloomberg BSYM, the only free and open symbology in market data, with NYSE Euronext proprietary data feeds, this move by NYSE Euronext and Bloomberg meets the need for open standards in reference data.   This innovative solution provides standardization and interoperability between NYSE Euronext’s data feeds and Bloomberg’s value-added content.

NYSE Euronext will distribute BSYM through its data feeds and web sites to ensure optimum availability and access to its global customer base.  This allows market participants to benefit from the flexibility of choice and relieves them of the burden of mapping between global and local security identifiers.

“An open source, truly integrated solution for market data distribution is long overdue.   NYSE Euronext is pleased to join with Bloomberg in delivering this innovative, market-based approach to benefit our customers and the investing public,” said Larry Leibowitz, Chief Operating Officer, NYSE Euronext.  “Taking the lead in providing a global uniform standard demonstrates our joint commitment to move the industry forward by providing increased transparency and improved access while lowering costs.”

“Bloomberg has revolutionized the market data industry by creating a free and open standard, Bloomberg Open Symbology.  BSYM contains the same identifiers used globally in the BLOOMBERG PROFESSIONAL® service, now available to everyone in the investing public,” said Mark Pesonen, head of Enterprise Products and Solutions at Bloomberg.  “Furthering our commitment to open standards, we now provide an integrated solution between BSYM and all NYSE Euronext feeds.  In an atmosphere of increased cross-border trading, this solution allows for quick integration into users’ systems to give the industry even greater flexibility.”

Bloomberg and NYSE Euronext will collaborate to maintain an open, market-based solution that integrates their core market information services as a vendor and supplier, respectively.  NYSE Euronext will offer its data feeds and products for coding and mapping on the BSYM platform through a tiered rollout that will begin in April with its popular OpenBookTM product.  After Bloomberg completes the mapping process for all New York Stock Exchange-listed ticker symbols and security identifiers, NYSE Euronext and its affiliates will globally distribute the new BSYM codes through its data feeds and related products.  Bloomberg Open Symbology can be accessed via the Web site
