International Securities Exchange
surged 46% after the exchange set plans to be acquired by a Deutsche Boerse affiliate.
The New York-based options exchange could be acquired for $67.50 a share, a 47% premium to Friday's closing price. A deal would combine the ISE with derivatives exchange Eurex, a venture of Deutsche Boerse and the Swiss Exchange.
"In founding ISE almost 10 years ago, we transformed the U.S. options market," said David Krell, CEO of ISE. "Our innovative products, electronic trading model, technology, market structure and entrepreneurial organization have enabled us to remain at the forefront of the options industry. Our principle strategic objective is to further grow our business both in terms of new products and new markets and in partnering with Eurex, we will be able to achieve our goal. By completing this transaction, we will be positioned to build upon ISE's successful business model and to solidify our future as an integral component of the largest transatlantic derivatives marketplace."

The deal is "still subject to the negotiation of final terms and documentation as well as approval by ISE's board," ISE said in a statement.
A spokeswoman for the ISE was not immediately available for comment on Monday.
Shares of ISE were up $19.54 to $65.26 early Monday.
