With the acquisition of Florida Chemical on May 10, 2013, the Company recorded increases in finite lived intangible assets of $14.1 million in patents and technology, $29.3 million in customer lists and $1.0 million in trademarks and brand names. In addition, the Company recorded $11.6 million in indefinite lived trademarks and brand names. These acquired intangible assets were recorded at fair value as of the date of acquisition.

Intangible assets acquired are amortized on a straight-line basis over two to 20 years. Amortization of intangible assets acquired totaled $3.9 million, $2.1 million and $2.1 million for the years end ended December 31, 2013, 2012 and 2011, respectively.

Amortization of deferred financing costs totaled $0.2 million, $0.9 million, and $3.1 million for the years ended December 31, 2013, 2012 and 2011, respectively. During 2013 and 2012, the carrying value of deferred financing costs was reduced by less than $0.1 million and $1.8 million, respectively, upon repayments of the Company’s convertible senior notes.
