NYSE Euronext

(NYX)

said Wednesday it agreed to sell a "significant" equity interest in NYSE Amex options, one of its two options exchanges in the U.S.

NYSE Euronext said Wednesday in a statement it would remain the largest shareholder in the entity.

The deal was reached with

and

, the exchange operator said.

NYSE Euronext said the deal aims to "enhance the competitive position of NYSE Amex options, while bringing competitive and operational benefits to the marketplace."

NYSE Euronext would continue to manage the day-to-day operations of NYSE Amex options, but the business would have a separate board and CEO.

The transaction, the terms of which weren't announced, could be completed by the end of 2009, NYSE Euronext said.
