Companies reporting major news:

Agrium Inc. (TSX:AGU). Fertilizer. Down eight cents, or 0.08 per cent, at $103.06 on 715,029 shares. The fertilizer giant made public the terms of a settlement deal with Jana Partners LLC that it says could have ended a bitter proxy fight two weeks ago, but ultimately remained unsigned. The New York hedge fund quickly fired back, saying Jana’s intentions have been mischaracterized as it agreed to neither the settlement nor the language in a joint news release on Monday.

Saputo Inc. (TSX:SAP). Down 20 cents, or 0.40 per cent, at $49.25 on 401,713 shares. The company’s nearly seven-year European venture is coming to an end after the Canadian cheese giant announced plans Monday to close cheese processing plants in Wales and Germany. The Montreal-based food company entered the European market in 2006 with the acquisition of Spezialitäten-Käserei De Lucia GmbH, a German cheese manufacturer producing Italian cheese specialties such as mozzarella, ricotta and mascarpone.
