CHICAGO, IL - FEBRUARY 11: A statue symbolizing industry stands in the courtyard outside the Chicago Board of Trade building on February 11, 2011 in Chicago, Illinois. The building is home of the CME Group which was formed following the merger of the Chicago Mercantile Exchange and the Chicago Board of Trade.
