revenues contributed by our North America operating segment increased 12.5 percent and 5.3 percent in 2011 and 2010, respectively, as a result of our acquisition of CCE's North American business on October 2, 2010. The CCE acquisition resulted in a decrease in the proportionate share of the Company's consolidated net operating revenues contributed by our operating segments outside of North America for both 2011 and 2010. The percentage of the Company's net operating revenues contributed by our Bottling Investments operating segment decreased 5.1 percent and 3.0 percent in 2011 and 2010, respectively, primarily due to the sale of our Norwegian and Swedish bottling operations to New CCE and the segment's proportionate decrease in the Company's consolidated net operating revenues due to the CCE acquisition in North America. Refer to the heading "Structural Changes, Acquired Brands and New License Agreements" above. 

The size and timing of structural changes are not consistent from period to period. 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, 2011, versus Year Ended December 31, 2010 

Our gross profit margin decreased to 60.9 percent in 2011 from 63.9 percent in 2010. The decrease was primarily due to the full year impact of consolidating CCE's North American business as well as a significant increase in commodity costs. The unfavorable impact of these items was partially offset by favorable geographic and product mix, price increases in many of our key markets and foreign currency exchange fluctuations. In addition, the sale of our Norwegian and Swedish bottling operations during the fourth quarter of 2010 had a favorable impact on our full year 2011 gross profit margin. 

The Company's acquisition of CCE's North American business during the fourth quarter of 2010 resulted in a significant adjustment to our overall cost structure, especially in North America. Finished products operations typically have lower gross profit margins and greater exposure to fluctuations in the cost of raw materials when compared to concentrate operations. The following inputs represent a substantial portion of the Company's total cost of goods sold: (1) sweeteners, (2) metals, (3) juices and (4) PET. The bulk of these costs reside within our North America and Bottling Investments operating segments. The cost to purchase these inputs increased significantly in 2011 when compared to 2010. As a result, the Company incurred incremental costs of $800 million related to these inputs during 2011. The Company anticipates that the cost of underlying commodities will continue to face upward pressure in 2012. We currently expect the incremental impact of increased commodity costs related to these inputs, primarily juices and sweeteners, to range between $350 million and $450 million on our full year 2012 consolidated results. 

Upon the close of our acquisition of CCE's North American business, the Company increased
