Fox River Environmental Matter In a decision issued on October 4, 2012, the Wisconsin federal court ruled in the Company's favor on the remaining state law counterclaims advanced by the defendant PRPs against the Company in the Fox River allocation litigation, and granted the Company summary judgment on pre-emption grounds. The court has asked the parties to confer on and file a proposed final judgment for the allocation case, and to deal with the remaining unresolved issue of insurance offsets applicable to counterclaims, or to advise why agreement cannot be reached.
