Fortron Industries LLC.
Fortron is a leading global producer of PPS, sold under the Fortron?
brand, which is used in a wide variety of automotive and other applications, especially those requiring heat and/or chemical resistance.
Fortron's facility is located in Wilmington, North Carolina.
This venture combines the sales, marketing, distribution, compounding and manufacturing expertise of Celanese with the PPS polymer technology expertise of Kureha America Inc.  Cellulose derivatives strategic ventures.
Our cellulose derivatives ventures generally fund their operations using operating cash flow and pay dividends based on each ventures' performance in the preceding year.
In 2014, 2013 and 2012, we received cash dividends of $115 million, $92 million and $83 million, respectively.
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:

Year Ended December 31, 2014 Compared with Year Ended December 31, 2013 Net sales decreased $54 million, or 4.4%, for the year ended December 31, 2014 compared to the same period in 2013 primarily due to lower acetate tow volume globally and lower acetate flake pricing under a legacy contract.
These were slightly offset by a 6% increase in acetate tow pricing reflecting favorable shifts in customer mix, higher acetate flake volume and higher volume in our food ingredients business primarily related to sorbates.
Operating profit increased $42 million, or 12.1%, for the year ended December 31, 2014 compared to the same period in 2013, despite lower net sales, primarily due to favorable acetate tow pricing as well as lower raw material and energy costs of $43 million as a result of productivity initiatives in our cellulose derivatives business.
Operating profit was also favorably impacted by a decrease in net periodic benefit cost of $22 million.
An increase in Other (charges) gains, net of $16 million primarily due to an arbitration award against a former utility operator at our cellulose derivatives manufacturing facility in Narrows, Virginia also contributed to the increase in operating profit.
Dividend income from cost investments increased $23 million for the year ended December 31, 2014 compared to the same period in 2013 primarily due to higher earnings from our cellulose derivatives ventures resulting from higher volume and acetate tow pricing as well as lower energy costs.
Year Ended December 31, 2013 Compared with Year Ended December 31, 2012 Net sales increased $28 million, or 2.4%, for the year ended December 31, 2013 compared to the same period in 2012 primarily due to higher pricing in the cellulose derivatives business partially offset by lower volume in both the cellulose derivatives and food ingredients businesses.
Acetate tow pricing increased 8% across all regions while volume declined due to the cessation of manufacturing of acetate flake and acetate tow at our Spondon, United Kingdom facility in November 2012.
Operating profit increased $95 million, or 37.8%, for the year ended December 31, 2013 compared to the same period in 2012 primarily due to the increase in acetate tow pricing and a $57 million favorable impact from the cessation of production of acetate flake and acetate tow at our Spondon, Derby, United Kingdom facility in November 2012, including lower energy and plant costs.
A decrease in net periodic benefit cost of $14 million contributed to the increase in operating profit.

Year Ended December 31, 2013 Compared with Year Ended December 31, 2012 Cash flow provided by operating activities increased by $40 million for the year ended December 31, 2013 compared to the same period in 2012.
The increase in cash provided by operations was primarily the result of stronger earnings performance and a reduction in pension plan and other postretirement benefit plan contributions of $192 million made during the year ended December 31, 2013 compared to the prior year.
These favorable impacts were partially offset by a decrease in dividends from our equity investments of $121 million primarily due to the absence of a $75 million cash dividend received from Polyplastics in 2012 as a result of an amendment to our joint venture and other related agreements and a $65 million increase in cash taxes paid.
Trade working capital is calculated as follows:
