As a result, anticipating the impact of such events on future net operating revenues, and other financial statement line items, usually is not possible. We expect structural changes to have an impact on our consolidated financial statements in future periods. 

Gross Profit Margin 

Year Ended December 31, 2010, versus Year Ended December 31, 2009 

Our gross profit margin decreased to 63.9 percent from 64.2 percent. The decrease was primarily due to the impact of our acquisition of CCE's North American business, partially offset by favorable geographic mix, product mix, the sale of our Norwegian and Swedish bottling operations and the deconsolidation of certain entities as a result of the Company's adoption of new accounting guidance issued by the FASB. 

Refer to the heading "Structural Changes, Acquired Brands and New License Agreements," above, for additional information regarding the impact of our acquisition of CCE's North American business, the sale of our Norwegian and Swedish bottling operations and the deconsolidation of certain entities as a result of the Company's adoption of new accounting guidance issued by the FASB. The favorable geographic mix was primarily due to many of our emerging markets recovering from the global recession at a quicker pace than our developed markets. Although this shift in geographic mix has a negative impact on net operating revenues, it generally has a favorable impact on our gross profit margin due to the correlated impact it has on our product mix. The product mix in the majority of our emerging and developing markets is more heavily skewed toward our sparkling beverage products, which generally yield a higher gross profit margin compared to our still beverages and finished products. Refer to the heading "Net Operating Revenues," above. 

In 2011, we expect our gross profit margin to decline due to the full year impact of consolidating CCE's North American business, as well as an increase in commodity costs. The acquisition of CCE's North American business has resulted in a significant adjustment to our overall cost structure, especially in North America. Finished products operations typically have lower gross profit margins and the additional commodity risk could lead to higher raw material costs in 2011. Subsequent to this transaction, approximately 35 percent of our consolidated cost of goods sold is comprised of the raw material and conversion cost associated with the following inputs: (1) sweeteners,

(2) metals, (3) juices and (4) PET. The majority of these costs are incurred by our North America and Bottling Investments operating segments. We anticipate that the cost of underlying commodities related to these inputs will continue to face upward pressure. We expect the full year 2011 impact of increased commodity costs on our total company results to range between $300 million and $400 million. 

Upon the close of our acquisition of CCE's North American business, we increased our hedging activities related to certain commodities in order to mitigate a portion of the price risk associated with forecasted purchases. Many of the derivative financial instruments used by the Company to mitigate
