The New York Stock Exchange (NYSE) is due to expand the business operations of its NYSE Technologies division in Northern Ireland.
The move will see the creation of up to 400 new jobs over the coming years. Invest Northern Ireland will provide up to £9.6 million to support the move of NYSE Technologies business operations into a new state-of-the-art development facility in Belfast by 2010.
The major investment by NYSE in Northern Ireland comes after it bought a Belfast software firm last year.
