Interest expense, net of capitalized interest increased $64 million, or 9.8%, to $710 million in 2013 from $646 million in 2012 primarily due to special charges of $92 million to recognize post-petition interest expense on unsecured obligations pursuant to the Plan and penalty interest related to 10.5% secured notes and 7.50% senior secured notes.
Other nonoperating expense, net of $84 million in 2013 consists principally of net foreign currency losses of $55 million and early debt extinguishment charges of $48 million.
Other nonoperating income in 2012 consisted principally of a $280 million special credit related to the settlement of a commercial dispute partially offset by net foreign currency losses.
Reorganization Items, Net Reorganization items refer to revenues, expenses (including professional fees), realized gains and losses and provisions for losses that are realized or incurred as a direct result of the Chapter 11 Cases.
The following table summarizes the components included in reorganization items, net on American’s consolidated statements of operations for the years ended December 31, 2013 and 2012 (in millions):
## Table 0 ##
(1) In exchange for employees’ contributions to the successful reorganization, including agreeing to reductions in pay and benefits, American agreed in the Plan to provide each employee group a deemed claim, which was used to provide a distribution of a portion of the equity of the reorganized entity to those employees.
Each employee group received a deemed claim amount based upon a portion of the value of cost savings provided by that group through reductions to pay and benefits as well as through certain work rule changes.
The total value of this deemed claim was approximately $1.7 billion.
(2) Amounts include allowed claims (claims approved by the Bankruptcy Court) and estimated allowed claims relating to (i) the rejection or modification of financings related to aircraft and (ii) entry of orders treated as unsecured claims with respect to facility agreements supporting certain issuances of special facility revenue bonds.
The Debtors recorded an estimated claim associated with the rejection or modification of a financing or facility agreement when the applicable motion was filed with the Bankruptcy Court to reject or modify such financing or facility agreement and the Debtors believed that it was probable the motion would be approved, and there was sufficient information to estimate the claim.
See Note 2 to American’s Consolidated Financial Statements in Part II, Item 8B for further information.
(3) Pursuant to the Plan, the Debtors agreed to allow certain post-petition unsecured claims on obligations.
As a result, during the year ended December 31, 2013, American recorded reorganization charges to adjust estimated allowed claim amounts previously recorded on rejected special facility revenue bonds of $180 million, allowed general unsecured claims related to the 1990 and 1994 series of special facility revenue bonds that financed certain improvements at JFK, and rejected bonds that financed certain improvements at ORD, which are included in the table above.
(4) The Plan allowed unsecured creditors receiving AAG Series A Preferred Stock a conversion discount of 3.5%.
Accordingly, American recorded the fair value of such discount upon the confirmation of the Plan by the Bankruptcy Court.
Our strategic affiliates as of December 31, 2017 are as follows:
## Table 1 ##
National Methanol Company (Ibn Sina).
National Methanol Company represents approximately 1% of the world's methanol production capacity and is one of the world's largest producers of methyl tertiary-butyl ether, a gasoline additive.
Its production facilities are located in Saudi Arabia.
Saudi Basic Industries Corporation ("SABIC") is responsible for all product marketing.
Methanol is a key feedstock for POM production and is produced by our Ibn Sina affiliate which provides an economic hedge against raw material costs in our engineered materials business.
Ibn Sina has constructed a 50,000 metric ton POM production facility in Saudi Arabia.
The new facility will supply POM to support Advanced Engineered Materials' future growth plans as well as our venture partners' regional business development and was declared commercially operational in the fourth quarter of 2017.
Upon successful startup of the POM facility, our indirect economic interest in Ibn Sina increased from 25% to 32.5%.
SABIC's economic interest will remain unchanged.
KEPCO.
KEPCO is the leading producer of POM in South Korea.
KEPCO has polyacetal production facilities in Ulsan, South Korea, compounding facilities for PBT and nylon in Pyongtaek, South Korea, and participates with Polyplastics and Mitsubishi Gas Chemical Company, Inc.  in a world-scale POM facility in Nantong, China.
Polyplastics.
Polyplastics is a leading supplier of engineered plastics.
Polyplastics is a manufacturer and/or marketer of POM, LCP and PPS, with principal production facilities located in Japan and Malaysia.
Fortron Industries LLC.
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 our sales, marketing, distribution, compounding and manufacturing expertise with the PPS polymer technology expertise of Kureha America Inc.  Cellulose derivatives strategic ventures.
Our cellulose derivatives ventures within our Consumer Specialties segment generally fund their operations using operating cash flow and pay dividends based on each ventures' performance in the preceding year.
In 2017, 2016 and 2015, we received cash dividends of $107 million, $107 million and $106 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").
O&R Electric Operations Electric Facilities O&R’s capitalized costs for utility plant, net of accumulated depreciation, for distribution facilities were $850 million and $830 million at December 31, 2015 and 2014, respectively.
For its transmission facilities, the costs for utility plant, net of accumulated depreciation, was $212 million at December 31, 2015 and 2014.
O&R, RECO and Pike, own, in whole or in part, transmission and distribution facilities which include 547 circuit miles of transmission lines, 14 transmission substations, 62 distribution substations, 86,794 in-service line transformers, 3,994 pole miles of overhead distribution lines and 1,889 miles of underground distribution lines.
O&R’s transmission system is part of the NYISO system except that portions of RECO’s system are located within the transmission area controlled by PJM.
Electric Sales and Deliveries O&R delivers electricity to its full-service customers who purchase electricity from the company.
The company also delivers electricity to its customers who purchase electricity from other suppliers through the company’s retail choice program.
The company charges all customers in its service area for the delivery of electricity.
O&R generally recovers, on a current basis, the cost of the electricity that it buys and then sells to its full-service customers.
It does not make any margin or profit on the electricity it sells.
O&R’s New York electric revenues (which accounted for 74 percent of O&R’s electric revenues in 2015) are subject to a revenue decoupling mechanism.
As a result, O&R’s New York electric delivery revenues are generally not affected by changes in delivery volumes from levels assumed when rates were approved.
O&R’s electric sales in New Jersey and Pennsylvania are not subject to a decoupling mechanism.
O&R’s electric sales and deliveries for the last five years were:

For further discussion of the company’s electric operating revenues and its electric results, see “Results of Operations” in Item 7.
For additional segment information, see Note N to the financial statements in Item 8.
Electric Peak Demand The electric peak demand in O&R’s service area occurs during the summer air conditioning season.
The weather during the summer of 2015 was cooler than design conditions.
O&R’s 2015 service area peak demand was 1,405 MW, which occurred on July 20, 2015.
The 2015 peak demand included an estimated 779 MW for O&R’s fullservice customers and 626 MW for customers participating in its electric retail choice program.
“Design weather” for the electric system is a standard to which the actual peak demand is adjusted for evaluation and planning purposes.
Since the NYISO can invoke demand reduction programs under specific circumstances, design conditions do not include these programs’ potential impact.
However, the O&R forecasted peak demand at design conditions does include the impact of certain demand reduction programs.
The company estimates that, under design weather conditions, the 2016 service area peak demand will be 1,632 MW, including an estimated 902 MW for its full-service customers and 730 MW for its electric retail choice customers.
The company forecasts an average annual growth in electric peak demand in the company’s service area over the next five years at design conditions to be approximately 0.3 percent per year.
During the year ended November 30, 2010, we recorded $10.5 million of our share of valuation adjustments related to the assets of unconsolidated entities in which we have investments, compared to $101.9 million for the year ended November 30, 2009.
