Amortization expense associated with intangible assets was $8.9 million, $9.2 million and $13.1 million for the years ended December 31, 2015, 2014 and 2013, respectively. Amortization expense associated with intangible assets is expected to be approximately $8.9 million per year in each of the next five years. In addition, as a result of the sales of the Algeciras Spirit and Huelva Spirit in 2014, the Partnership’s intangible assets relating to these two conventional tankers were fully amortized in 2014.

The carrying amount of goodwill as at each of December 31, 2015 and 2014 for the Partnership’s liquefied gas segment was $35.6 million. In 2015 and 2014, the Partnership conducted its annual goodwill impairment review of its liquefied gas segment and concluded that no impairment had occurred.
