NYSE Blue will offer services such as integrated pre-trade and post-trade platforms, environmental registry services, markets reference data and the BlueNext spot emissions platform.

In September 2010, the companies announced their intention to create NYSE Blue.

Under the terms of the deal, NYSE Euronext contributed its 60% shareholding in French emissions exchange BlueNext and is the majority owner.

The transaction has been approved by regulators and APX shareholders, who will retain a minority stake in NYSE Blue in return for their shares in APX.

Brian Storms, who served as chairman and CEO of APX, will be the new chairman and CEO of NYSE Blue.

NYSE Euronext CEO Duncan Niederauer said that the NYSE Euronext looks forward to working with Brian and his team on the formation of NYSE Blue, and to strengthen the position in environmental markets on a global scale by expanding the portfolio of services to the company’s listed companies and markets’ customers, and attracting new partners and customers.

Storms said that bringing together APX’s expertise in market infrastructure and BlueNext’s proven exchange allows NYSE Blue to effectively provide global environmental market offerings.
