One explanation for the lower metrics is that Canadian Natural sells its oil via WTI prices, which sell at a discount to Brent prices (which Suncor utilizes). Additionally, as mentioned before, Suncor's various lines of business enable it to survive better through difficult times. But, Canadian Natural is still earning investors a return—unlike Enerplus Resources ( ERF ) and Talisman. However, it is important to recognize Enerplus' unique value proposition; it offers investors an unorthodox dividend payment. Plus, because it is only about 3% above its book value, investors could consider it a safe haven compared to firms trading at higher prices.
