China acetate strategic ventures.
We hold an approximate 30% ownership interest in three separate acetate production ventures in China.
These include the Nantong Cellulose Fibers Co.  Ltd. , Kunming Cellulose Fibers Co.  Ltd.  and Zhuhai Cellulose Fibers Co.  Ltd.
The China National Tobacco Corporation, the Chinese state-owned tobacco entity, controls the remaining ownership interest in each of these ventures.
With an estimated 30% share of the world's cigarette production and consumption, China is the world's largest and fastest growing area for acetate tow products according to the 2009 Stanford Research Institute International Chemical Economics Handbook.
Combined, these ventures are a leader in Chinese domestic acetate production and are well positioned to supply Chinese cigarette producers.
In December 2009, we announced plans with China National Tobacco to expand our acetate flake and tow capacity at our venture's Nantong facility and we received formal approval for the expansions, each by 30,000 tons, during 2010.
Since their inception in 1986, the China acetate ventures have completed 12 expansions, leading to earnings growth and increased dividends.
Our Chinese acetate ventures fund their operations using operating cash flow.
During 2011, we made contributions of $8 million related to the capacity expansions in Nantong and have committed contributions of $9 million in 2012.
In 2010, we made contributions of $12 million.
Our Chinese acetate ventures pay a dividend in the second quarter of each fiscal year, based on the ventures' performance for the preceding year.
In 2011, 2010 and 2009, we received cash dividends of $78 million, $71 million and $56 million, respectively.
Although our ownership interest in each of our China acetate ventures exceeds 20%, we account for these investments using the cost method of accounting because we determined that we cannot exercise significant influence over these entities due to local government investment in and influence over these entities, limitations on our involvement in the day-to-day operations and the present inability of the entities to provide timely financial information prepared in accordance with generally accepted accounting principles in the United States (“US GAAP”).  ?
