Members of the Chicago Board of Trade (CBOT) are to share a windfall of $44.8m (€35.6m) following the dissolution of a technology partnership known as Ceres Trading.

The entity was a joint venture between the CBOT, which held 10%, and its members, which together held 90%. The CBOT's decision to switch trading to a new technology system, Liffe Connect, last November, meant Ceres Trading, which had previously provided technological development and support, could be liquidated.
