Saputo Inc., Canada's biggest milk processor, neared control of Warrnambool Cheese & Butter Factory Co., as the Australian dairy producer's second-largest shareholder agreed to sell its holding. Bega Cheese Ltd., which withdrew its own offer last month for the maker of Sungold milk, will sell its 18.8 percent stake to Saputo, which made a A$537 million ($473 million) bid, according to a statement today. The sale will take Saputo's stake to 45.2 percent, based on data compiled by Bloomberg.
