Cost of Sales and Lower of Cost or Market Adjustments

Due to fluctuating commodity prices, we recognize lower of cost or market adjustments when the carrying value of our available-for-sale inventories exceeds their net realizable value.  The following table presents our total cost of sales amounts and lower of cost or market adjustments for the periods indicated:

		For the Three Months Ended June 30,								For the Six Months Ended June 30,
		2015				2014				2015				2014
Cost of sales (1)		$	5,257.9			$	10,705.3			$	10,936.0			$	21,758.0
Lower of cost or market adjustments			0.5				2.7				4.0				7.9
(1) Cost of sales is a component of “Operating costs and expenses” as presented on our Unaudited Condensed Statements of Consolidated Operations. Fluctuations in these amounts are primarily due to changes in energy commodity prices and sales volumes associated with our marketing activities.
