In a prior week you learned that "Cash is King", so true. It seems in the past few years, we can say the same of OIL - Oil is King. Living in Ontario we are not so exposed to the Oil extraction, Oil mining and Oil processing done in Canada but also represents the lifeblood to Canadian business.

Find a Canadian Company, with involvement in Oil industry, any is acceptable and on Toronto Stock Exchange and that have been subject to asset impairment. What amounts and how did it affect future stock growth?
