Comparison of Cumulative Total Return
affiliate.
Equity investment earnings for Polyplastics increased as a result of higher volume, lower turnaround expenses and lower restructuring charges related to one of their affiliates.
Year Ended December 31, 2013 Compared with Year Ended December 31, 2012 Advanced Engineered Materials' net sales increased $91 million, or 7.2%, for the year ended December 31, 2013 compared to the same period in 2012 primarily due to increased POM and LFRT volume resulting from increased penetration in automotive applications in the Americas and Asia.
Volume in Asia also improved across all product lines due to targeted growth programs in consumer and industrial applications.
Higher pricing and product mix, mainly for medical applications, also contributed to the increase in net sales for the year ended December 31, 2013.
Operating profit increased $809 million, or 851.6%, for the year ended December 31, 2013 compared to the same period in 2012 primarily driven by the recognition of a gain of $742 million, which represents the deferred proceeds in excess of divested assets as a result of the 2006 settlement agreement with Fraport to move our German POM operations.
A decrease in net periodic benefit cost of $24 million also contributed to the increase in operating profit.
Increased volume, a shift in product mix to higher margin medical applications and slightly lower raw material costs also contributed to increased operating profit.
These changes were partially offset by higher energy costs of $21 million resulting from higher prices and usage and an $11 million negative impact from Other (charges) gains, net for the year ended December 31, 2013 as compared to the same period in 2012.
The negative impact of Other (charges) gains, net primarily reflects an increase of $6 million in costs associated with the relocation and expansion of our German POM operations and a 2012 $4 million legal reserve reduction associated with plumbing actions.
Equity in net earnings (loss) of affiliates decreased $42 million for the year ended December 31, 2013 compared to the same period in 2012 primarily due to decreases in equity investment earnings from our Ibn Sina and Polyplastics strategic affiliates of $19 million and $18 million, respectively.
The decrease in Ibn Sina equity investment earnings was largely the result of the timing of turnaround activity, lower methyl tertiary-butyl ether pricing and lower sales volume.
Polyplastics' equity investment earnings decreased due to slightly lower pricing, higher turnaround and sales expenses and restructuring charges related to one of their affiliates.
