Cameco Corporation is the worlds largest publicly traded uranium company, based in Saskatoon, Saskatchewan. In 2015, it was the worlds second largest uranium producer, accounting for 18% of world production. "Cameco - Canadian Mining and Energy Corporation" was formed in 1988 by the merger and privatization of two crown corporations: the federally owned Eldorado Nuclear Limited (known previously as Eldorado Mining and Refining Limited) and Saskatchewan-based Saskatchewan Mining Development Corporation (SMDC). The name was later shortened to "Cameco Corporation". The new company was initially owned 62% by the provincial government and 38% by the federal government. The initial public offering (IPO) for 20% of the company was conducted in July, 1991. Government ownership of the company decreased over the next eleven years, with full privatization occurring in February, 2002.
