from certain joint ventures, in which the Company is a partner but to which the Company does not sell concentrate. 

Company-wide concentrate sales volume and unit case volume both grew 6 percent in 2007 compared to 2006. Differences between unit case volume and concentrate sales volume growth rates for all segments were primarily due to timing of concentrate shipments. 

Net Operating Revenues 

Net operating revenues increased by $3,087 million, or 11 percent, in 2008 compared to 2007 and by $4,769 million, or 20 percent, in 2007 compared to 2006. The following table illustrates, on a percentage basis, the estimated impact of key factors resulting in increases in net operating revenues 

Refer to the heading "Beverage Volume" for a discussion of concentrate sales volume. Also included in concentrate sales volume is the impact of acquired beverage companies, including, among others, glacéau, and the acquisition of trademarks. 

"Structural changes" refers to acquisitions or dispositions of bottling, distribution or canning operations and consolidation or deconsolidation of bottling and distribution entities for accounting purposes. Structural changes had a net zero percent impact on net operating revenues in 2008 compared to 2007. The increase in net operating revenues attributable to the full year impact of prior year acquisitions, including, but not limited to, 18 German bottling and distribution operations, NORSA and CCBPI was offset by the sale of Remil and the sale of a portion of our ownership interest in Coca-Cola Pakistan, which resulted in its deconsolidation. Refer to Note 3 and Note 20 of Notes to Consolidated Financial Statements. 

Price and product/geographic mix increased net operating revenues by 3 percent in 2008 compared to 2007, primarily due to favorable pricing and product/package mix across the majority of the operating segments. 

The favorable impact of currency fluctuations increased net operating revenues by 4 percent in 2008 compared to 2007. The U.S. dollar weakened against certain key currencies in 2008 including, but not limited to, the euro, Japanese yen and Brazilian real. The fluctuations in these currencies favorably impacted the Europe, Pacific, Latin America and Bottling Investments operating segments. The favorable impact of fluctuations in the aforementioned currencies was partially offset by the unfavorable impact of the U.S. dollar strengthening against the South African rand and the British pound during 2008. The fluctuations in these currencies unfavorably impacted the Eurasia and Africa, Europe and Bottling Investments operating segments. Refer to the heading "Liquidity, Capital Resources and Financial Position—Foreign Exchange." 

In 2007, structural changes increased net operating revenues by 8 percent compared to 2006. The increase in net operating revenues attributable to structural changes was primarily due to the impact of acquisitions made during 2007, including, but not limited to, 18 German bottling and distribution operations, NORSA and CCBPI. In addition to the partial year impact of 2007 acquisitions, the full year impact of the acquisition of CCCIL and the consolidation of Brucephil,
