Acetate Products has production sites in the United States, Mexico, the United Kingdom and Belgium, along with sites at its three acetate ventures in China.
In November 2012, we ceased manufacturing acetate tow and acetate flake at our Spondon, Derby, United Kingdom site.
We will continue to manufacture our Clarifoil?
film at this facility.
Our Nutrinova business is a leading international supplier of premium quality ingredients for the food, beverage and pharmaceutical industries.
The company produces and sells Sunett?
(acesulfame potassium), a high intensity sweetener.
It is also one of the world's largest producers of food protection ingredients, such as potassium sorbates and sorbic acid.
Nutrinova's expertise is based on its more than sixty years of experience in developing and marketing specialty ingredients to the food and beverage and pharmaceutical industries.
While this business has traditionally focused on providing low calorie sweeteners in the beverage industry, it continues to target high value opportunities in more diverse applications such as oral hygiene, pharmaceuticals, dairy and cereals.
During 2012, Nutrinova announced Sunett?
SL, the first new line of product from the Nutrinova's SunsationSM platform.
Sunett?
SL products are drop-in solutions that can be easily incorporated into customers' food and beverage formulations, helping customers bring products to market faster.
Sensory tests carried out by an accredited external institute confirm that Sunett?
SL significantly improves the sweetness and mouth-feel perception of sugar-free and sugar-reduced products.
Nutrinova has a production facility in Germany, with sales and distribution facilities in all major regions of the world.  ?
Key Products Acetate flake, acetate tow and acetate film (Clarifoil).
Acetate tow is a fiber used primarily in cigarette filters.
In order to produce acetate tow, we first produce acetate flake by processing wood pulp with acetic acid and acetic anhydride.
Wood pulp generally comes from reforested trees and is purchased externally from a variety of sources, and acetic anhydride is an intermediate chemical that we produce from acetic acid.
The acetate flake is then further processed into acetate tow.
Flake can also be solvent cast to create a film which is primarily used in packaging for food and high-end luxury goods.
Sales of acetate tow amounted to 15%, 14% and 15% of our consolidated net sales for the years ended December 31, 2012, 2011 and 2010, respectively.
Sunett?
sweeteners.
Acesulfame potassium, a high intensity sweetener sold under the trademark Sunett?
, is used in a variety of beverages, confections and dairy products throughout the world.
Sunett?
sweetener is the ideal blending partner for caloric and non-caloric sweeteners and is recognized for its consistent product quality and reliable supply.
Food protection ingredients.
Nutrinova's food protection ingredients are mainly used in foods, beverages and personal care products.
Sorbates pricing is extremely sensitive to demand and industry capacity and is not necessarily dependent on the cost of raw materials.  ?

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.
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:
