IntercontinentalExchange yesterday ended months of uncertainty over the future of some of NYSE Euronext's key business units, as it laid out its strategic masterplan for merging the two exchange groups.

In the first investor call since closing a $11 billion deal for NYSE Euronext last week, ICE's senior management - including chairman and chief executive Jeff Sprecher - set out plans for NYSE's European exchanges known as Euronext, its Liffe derivatives franchise and systems unit NYSE Technologies.
