Amortization expense for intangible assets was $3.3 million, $3.7 million and $2.8 million in 2014, 2013 and 2012, respectively.
NACoal's long-lived asset evaluation during 2014 resulted in the Company recording a non-cash, impairment charge with respect to its Reed Minerals mining operations asset group of $105.1 million recorded on the line Reed Minerals long-lived asset impairment charge in the Consolidated Statements of Operations, of which $5.7 million was for intangible assets. The fair value of the intangible assets was calculated using an income approach and reduced the carrying value of the Reed Minerals' intangible assets to zero. See Note 10 for further discussion of this nonrecurring fair value measurement.
Expected annual amortization expense of NACoal's coal supply agreement for the next five years is as follows: $2.7 million in 2015 and 2016, $2.8 million in 2017, 2018 and 2019, respectively. The coal supply agreement is amortized based on units of production over the term of the agreement, which is estimated to be 30 years.
Expected annual amortization expense of HBB's intangible assets for the next five years is $1.4 million in 2015, 2016, 2017, 2018 and 2019. The weighted average amortization period for HBB's intangible assets is approximately 9 years.
