Net Operating Revenues by Operating Segment 

Information about our net operating revenues by operating segment as a percentage of Company net operating revenues is as follows 

The percentage contribution of each operating segment fluctuates over time due to net operating revenues in certain operating segments growing at

other operating segments. Net operating revenue growth rates are impacted by sales volume, structural changes, price and product/geographic mix,

fluctuations. In 2012, the percentage contribution of each operating segment did not change significantly when compared to 2011. In 2011, the percentage of the Company's net operating revenues contributed by our North America operating segment increased 12.5 percentage points when compared to 2010 as a result of our acquisition of CCE's former North America 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. In addition, the percentage of the Company's net operating revenues contributed by our Bottling Investments operating segment decreased 5.1 percentage points in 2011 when compared to 2010, 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, 2012, versus Year Ended December 31, 2011 

Our gross profit margin decreased to 60.3 percent in 2012 from 60.9 percent in 2011. This decrease reflected the unfavorable impact of continued increases in commodity costs during 2012 as well as temporary shifts in channel and package mix across markets as a result of the impact of current global economic conditions on consumers. In addition, our gross profit margin was unfavorably impacted as a result of ongoing fluctuations in foreign currency exchange rates and the impact of our acquisition of Great Plains in North America as well as our acquisition of bottling operations in Vietnam, Cambodia and Guatemala. The impact of these items was partially offset by favorable geographic mix as well as price increases in many of our key markets. 

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 majority of these costs are included in our North America and Bottling Investments operating segments. The cost to purchase these inputs continued to increase in 2012 when
