Selling, general and administrative expenses increased $4,282 million, or 33 percent. Foreign currency fluctuations increased selling, general and administrative expenses by

3 percent. The decrease in stock-based compensation expense was primarily related to the impact of modifications made to certain replacement performance share unit awards on our prior year results, partially offset by higher estimated payouts tied to performance in conjunction with our long-term incentive compensation programs. Advertising expenses increased during the year and reflect the Company's continued investment in the health and strength of our brands and building market execution capabilities. The increase in bottling and distribution expenses was primarily due to the full year impact of consolidating CCE's North American business in addition to our continued investments in our other bottling operations around the world. This increase was partially offset by the full year impact of the sale of our Norwegian and Swedish bottling operations to New CCE during the fourth quarter of 2010. Other operating expenses decreased during the year, partially reflecting the impact of the Company's productivity and integration initiatives.

Refer to the heading "Critical Accounting Policies and Estimates — Pension Plan Valuations" above and Note 13 of Notes to Consolidated Financial Statements for additional information related to the discount rates used by the Company.

This expected cost does not include the impact of any future stock-based compensation awards. Refer to Note 12 of Notes to Consolidated Financial Statements.
