asset impairments included the reorganization of the North American business around three main business units: Sparkling Beverages, Still Beverages and Emerging Brands. They also included the plan to close a beverage concentrate manufacturing and distribution plant in Drogheda, Ireland, as well as individually insignificant streamlining activities throughout many other business units. Refer to Note 18 of Notes to Consolidated Financial Statements. Also in 2007, other operating charges included charges related to asset impairments, none of which was individually significant. 

During 2006, our Company recorded other operating charges of $185 million. Of these charges, approximately $108 million were primarily related to the impairment of assets and investments in our bottling operations, approximately $53 million were the result of contract termination fees related to production capacity efficiencies and approximately $24 million were related to other restructuring costs. None of these charges was individually significant. The impairment charges were primarily the result of a revised outlook for certain assets and bottling operations in Asia, which had been impacted by unfavorable market conditions and declines in volume. Refer to the discussion under "Critical Accounting Policies and Estimates—Goodwill, Trademarks and Other Intangible Assets," and Note 19 of Notes to Consolidated Financial Statements. 

As demonstrated by the tables above, the percentage contribution to operating income and operating margin by each operating segment fluctuated from year to year. Operating income and operating margin by operating segment were influenced by a variety of factors and events including the following: 

In 2008, foreign currency exchange rates favorably impacted operating income by approximately 6 percent, primarily due to a weaker U.S. dollar compared to the euro, Japanese yen and Brazilian real, which had a favorable impact on the Europe, Pacific, Latin America and Bottling Investments operating segments. The favorable impact of a weaker U.S. dollar compared to the aforementioned currencies was partially offset by the impact of a stronger U.S. dollar compared to the South African rand and the British pound, which had an unfavorable impact on the Eurasia and Africa, Europe and Bottling Investments operating segments. Refer to the heading "Liquidity, Capital Resources and Financial Position—Foreign Exchange." 

In 2008, price increases across the majority of operating segments had a favorable impact on both operating income and operating margins. 

In 2008, increased spending on marketing and innovation activities impacted the majority of the operating segments' operating income and operating margins. Refer to the heading "Selling, General and Administrative Expenses," above. 

In 2008, increases in the cost of raw materials and product mix, primarily as a result of finished goods businesses, adversely impacted North America's operating income and operating margin. 

In 2008, our operating margin was unfavorably impacted by the full year impact of acquisitions made during 2007, including, but not limited to, 18 German bottling and distribution
