NYSE Euronext Partners With ASSET4 to Provide Corporate Transparency Tool to Listed Issuers

New Solution to Help NYSE-Listed Companies Enhance Corporate Governance and
Transparency
NEW YORK--(Business Wire)--
NYSE Euronext (NYX) and ASSET4, a leading provider of environmental, social and
corporate governance (ESG) information solutions, today announced that they will
collaborate to provide tools to help NYSE-listed companies benchmark their
extra-financial policies and practices.

NYSE Euronext will provide the ASSET4 assetmasterExecutive solution to a number
of NYSE-listed companies, enabling them to manage risk, enhance corporate
governance practices and increase accountability. This follows a pilot program
during which NYSE Euronext-listed issuers successfully incorporated the ASSET4
solution into their corporate responsibility evaluation processes.

"Environmental, social and governance (ESG) issues have now become very
important factors affecting a company`s overall performance and risk profile,"
said Joseph Mecane, EVP and Chief Administrative Officer, U.S. Markets, NYSE
Euronext. "ASSET4 can provide corporate leaders a sustainability matrix through
which they manage their corporate social responsibility strategies with
increased accuracy. We are pleased to work with ASSET4, and our collaboration
underscores NYSE Euronext`s commitment to providing world-class value-added
services to our listed companies."

"Our partnership with NYSE Euronext is a major milestone in the recognition of
the increasing impact that ESG issues have on corporate performance and risk,"
said Peter Ohnemus, CEO and President of ASSET4. "Investors and corporate CEOs
understand the need for a new level of transparency in the way they do business
and conduct their communications. assetmasterExecutive gives corporate
executives, board members, CSR managers, investor relations and corporate
communication professionals the ability to monitor and benchmark their own
extra-financial performance and risk factors, and in turn prepare them for the
new business and regulatory reality that will be emerging in the months and
years to come."

NYSE Euronext is the first major stock exchange in the world to offer this tool
to its issuers, reinforcing its own commitment to corporate transparency. In
2008, NYSE Euronext was ranked among the "World`s Most Ethical Companies" in a
survey by Etisphere, the only exchange group in the world to make it into this
annual ranking for sustainable, ethical business practices.

Background:
The assetmasterExecutive solution, based on ASSET4`s world`s largest database of
objective and transparent ESG information, enables users to analyse an expanded
set of competitive parameters that include their level of carbon risk, board
independence and employee satisfaction. With one click of the mouse users can
evaluate extra-financial key performance indicator (KPI) configurations (e.g.
one based on the Global Reporting Initiative) to monitor how their own company
and their peers are performing. In addition, within each standard or customised
benchmark the best-in-class company is identified for each KPI, enabling users
to see in what areas they may be a leader and where a laggard. Benchmarks can
include any of the over 2,600 companies covered by ASSET4.
