CELANESE CORPORATION AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued) The total assets and liabilities associated with the Company’s equity method investments are as follows:
## Table 0 ##
Cost Method The Company’s investments accounted for under the cost method of accounting are as follows:
## Table 1 ##
Certain cost investments where the Company owns greater than a 20% ownership interest are accounted for under the cost method of accounting because the Company cannot exercise significant influence over these entities.
The Company determined that it cannot exercise significant influence over these entities due to local government investment in and influence over these entities, limitations on the Company’s involvement in the day-to-day operations and the present inability of the entities to provide timely financial information prepared in accordance with US GAAP.
During 2007, the Company wrote-off its remaining A1 million ($1 million) cost investment in European Pipeline Development Company B. V.  (“EPDC”) and expensed A7 million ($9 million), included in Other income (expense), net, associated with contingent liabilities that became payable due to the Company’s decision to exit the pipeline development project.
In June 2008, the outstanding contingent liabilities were resolved and the Company recognized a gain of A2 million ($2 million), included in Other income (expense), net, in the consolidated statements of operations to remove the remaining accrual.
The investment in EPDC related to the construction of a pipeline system, solely dedicated to the transportation of propylene, which was to connect Rotterdam via Antwerp, Netherlands, with the Company’s Oberhausen and Marl production facilities in Germany.
However, on February 15, 2007, EPDC shareholders voted to cease the pipeline project as originally envisaged and go into liquidation.
The Company was a 12.5% shareholder of EPDC.
During 2007, the Company fully impaired its $5 million cost investment in Elemica Corporation (“Elemica”).
Elemica is a network for the global chemical industry developed by 22 of the leading chemical companies in the world for the benefit of the entire industry.
The Company is a 1.83% shareholder of Elemica through its preferred share holdings.
As part of Elemica’s planned capital reorganization in 2007, its board of directors has proposed to convert all outstanding preferred stock into shares of Elemica’s common stock.
Based on the Company’s analysis of
German InfraServ Entities On January 1, 1997, coinciding with a reorganization of the Hoechst businesses in Germany, real estate service companies ("InfraServ Entities") were created to own directly the land and property and to provide various technical and administrative services at each of the manufacturing locations.
The Company owns manufacturing facilities at the InfraServ location in Frankfurt am Main-Hoechst, Germany and holds equity interests in the companies, which own and operate the former Hoechst sites in Frankfurt am Main-Hoechst, Gendorf and Knapsack, all of which are located in Germany.
InfraServ Entities are liable for any residual contamination and other pollution because they own the real estate on which the individual facilities operate.
In addition, Hoechst, and its legal successors, as the responsible party under German public law, is liable to third parties for all environmental damage that occurred while it was still the owner of the plants and real estate (Note 23).
The contribution agreements entered into in 1997 between Hoechst and the respective operating companies, as part of the divestiture of these companies, provide that the operating companies will indemnify Hoechst, and its legal successors, against environmental liabilities resulting from the transferred businesses.
Additionally, the InfraServ Entities have agreed to indemnify Hoechst, and its legal successors, against any environmental liability arising out of or in connection with environmental pollution of any site.
The InfraServ partnership agreements provide that, as between the partners, each partner is responsible for any contamination caused predominantly by such partner.
Any liability, which cannot be attributed to an InfraServ partner and for which no third party is responsible, is required to be borne by the InfraServ partnership.
Also, under lease agreements entered into by an InfraServ partner as landlord, the tenants agreed to pay certain remediation costs on a pro rata basis.
If an InfraServ partner defaults on its respective indemnification obligations to eliminate residual contamination, the owners of the remaining participation in the InfraServ companies have agreed to fund such liabilities, subject to a number of limitations.
To the extent that any liabilities are not satisfied by either the InfraServ Entities or their owners, these liabilities are to be borne by the Company in accordance with the demerger agreement.
However, Hoechst, and its legal successors, will reimburse the Company for two-thirds of any such costs.
Likewise, in certain circumstances the Company could be responsible for the elimination of residual contamination on several sites that were not transferred to InfraServ companies, in which case Hoechst, and its legal successors, must also reimburse the Company for two-thirds of any costs so incurred.
The German InfraServ Entities are owned partially by the Company (Note 8), as noted below, and the remaining ownership is held by various other companies.
The Company's ownership interest and environmental liability participation percentages for such liabilities, which cannot be attributed to an InfraServ partner are as follows:

US Superfund Sites In the US, the Company may be subject to substantial claims brought by US federal or state regulatory agencies or private individuals pursuant to statutory authority or common law.
In particular, the Company has a potential liability under the US Federal Comprehensive Environmental Response, Compensation and Liability Act of 1980, as amended, and related state laws (collectively referred to as "Superfund") for investigation and cleanup costs at certain sites.
At most of these sites, numerous companies, including the Company, or one of its predecessor companies, have been notified that the Environmental Protection Agency, state governing bodies or private individuals consider such companies to be potentially responsible parties ("PRP") under Superfund or related laws.
The proceedings relating to these sites are in various stages.
The cleanup process has not been completed at most sites and the status of the insurance coverage for some of these proceedings is uncertain.
Consequently, the Company cannot accurately determine its ultimate liability for investigation or cleanup costs at these sites.
As events progress at each site for which it has been named a PRP, the Company accrues, as appropriate, a liability for site cleanup.
Such liabilities include all costs that are probable and can be reasonably estimated.
In establishing these liabilities, the Company considers its shipment of waste to a site, its percentage of total waste shipped to the site, the types of wastes
year.
Beginning in 2013, the ventures pay dividends on a quarterly basis.
In 2013, 2012 and 2011, we received cash dividends of $92 million, $83 million and $78 million, respectively.
In 2012 our Nantong venture completed an expansion of its acetate flake and acetate tow capacity, each by 30,000 tons.
We made contributions of $29 million from 2009 through 2012 related to the capacity expansion in Nantong.
Similar expansions since the ventures were formed have led to earnings growth and increased dividends for the Company.
According to the Euromonitor database services, China is estimated to have had a 42% share of the world's 2012 cigarette consumption.
Cigarette consumption in China is expected to grow at a rate of 1.9% per year from 2012 through 2017.
Combined, these ventures are a leader in Chinese domestic acetate production and we believe we are well positioned to supply Chinese cigarette producers.
Although our ownership interest in each of our cellulose derivatives 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 of America ("US GAAP").  ?
Other Equity Method Investments InfraServs.
We hold indirect ownership interests in several German InfraServ Groups that own and develop industrial parks and provide on-site general and administrative support to tenants.
Our ownership interest in the equity investments in InfraServ affiliates are as follows:
