Shearman & Sterling and Sullivan & Cromwell have won lead roles on Nasdaq OMX and the Intercontinental Exchange (ICE)’s $11.3bn (£7bn) bid for NYSE Euronext, reports The Am Law Daily.

Nasdaq and ICE announced on Friday (1 April) that they had teamed up for the bid, around six weeks after German exchange Deutsche Boerse agreed to purchase the New York Stock Exchange’s parent for $10bn (£6.2bn).
