The IPR&D intangible asset was recorded in connection with the acquisition of CuraGen and relates to the development of CDX-011. At the date of acquisition, CDX-011 had not yet reached technological feasibility nor did it have any alternative future use. The Company recently completed a randomized Phase 2b study of CDX-011 for the treatment of advanced breast cancer. Amortization expense for intangible assets was $1.1 million, $1.9 million and $3.1 million for the years ended December 31, 2012, 2011 and 2010, respectively. The estimated future amortization expense of intangible assets for the years ended December 31, 2013, 2014, 2015, 2016 and 2017 is $1.0 million, $1.0 million, $1.0 million, $1.0 million and $0.9 million, respectively.
