The staff and management of Liffe stand to share 35m (€56.4m) in profits from option and incentive schemes if, as analysts expect, bidders offer 15 a share for the derivatives exchange.
The three senior directors, Sir Brian Williamson, chairman, Hugh Freedberg, chief executive, and John Foyle, deputy chief executive, stand to share a profit of 12.8m.
This is in addition to what they will receive for the shares they bought themselves, worth 1.26m at 15 a share. It is not, however, clear how much they paid for them.
The London International Financial Futures & Options Exchange is the subject of several takeover approaches. The London Stock Exchange has declared its interest, but other interested parties include Euronext, the pan-European exchange operator, the Chicago Mercantile Exchange, and Nasdaq.
