The greatest tragedy in BHP Billiton's $38.6-billion (U.S.) bid for the Potash Corporation of Saskatchewan (PCS) is that the Government of Saskatchewan previously sold PCS for just $630 million. This privatization was the worst fiscal decision in the province's history and has been aggravated by subsequent royalty giveaways to private potash companies.
PCS was created in 1975 as a provincial Crown corporation. The Saskatchewan government privatized it in 1989, selling all of its shares by 1994.
Presumably, the proceeds were deducted from the provincial deficit. Borrowing $630 million at 10 per cent interest, compounded over two decades, would have added $4.2-billion of provincial debt by now.
