Crown Investment Corporation (CIC) of Saskatchewan and its partners Mosaic Corporation and CIBC had decided to sell a fertilizer plant that they jointly owned. Now CIC and its associates had to come up with a value assessment and mode of sale.

In April 2007, the senior vice-president and chief financial officer (CEO) of Crown Investments Corporation of Saskatchewan (CIC) was faced with a challenging decision. CIC was contemplating the sale of 50 per cent interest in a heavy oil upgrader and wanted an assessment of the worth of the company. To obtain a reasonable estimate, the CEO had instructed an independent advisor with industry experience to provide input. In addition to receiving an estimate of value (based on the methods of free cash flow, comparables and precedent transactions), the CEO also had to formulate a strategy for selling off the company.
