Integration of Our German Bottling and Distribution Operations 

The Company's integration initiatives include costs related to the integration of 18 German bottling and distribution operations acquired in 2007. We incurred expenses of 1$48 million in 2012 related to this initiative. The expenses recorded in connection with these integration activities have been primarily due to involuntary terminations. The Company began these integration initiatives in 2008 and has incurred total pretax expenses of $440 million since they commenced. The Company is currently reviewing other integration and restructuring opportunities within the German bottling and distribution operations, which if implemented will result in additional charges in future periods. However, as of December 31, 2012, the Company had not finalized any additional plans. Refer to Note 18 of Notes to Consolidated Financial Statements.
