Norwegian investment firm Kistefos contends that Trico misled investors during a recent proxy battle by saying that Kistefos' attempt to get two nominees on Trico's board could lead to a violation of the Jones Act. The law requires that goods transported between U.S. ports be carried by vessels built, owned and staffed by Americans and registered in the U.S. Kistefos wants Trico's board to look into this and other issues. (For more on the battle, see the Activist Spotlight, at right.) Kistefos, with 3,535,959 shares (18.4% of the total outstanding), is Trico's top stockholder.
