Note 6 — Goodwill and Intangible Assets
Abbott recorded goodwill of approximately $274 million in 2013 related to the acquisitions of IDEV Technologies and OptiMedica. Goodwill related to the IDEV acquisition was allocated to the Vascular Products segment and goodwill related to OptiMedica was allocated to a non-reportable segment. Foreign currency translation and other adjustments decreased goodwill in 2013 and 2011 by $168 million and $225 million, respectively, and increased goodwill in 2012 by $69 million. In addition, in connection with the separation of AbbVie on January 1, 2013, Abbott transferred approximately $6.1 billion of goodwill to AbbVie. The amount of goodwill related to reportable segments at December 31, 2013 was $2.9 billion for the Established Pharmaceutical Products segment, $286 million for the Nutritional Products segment, $444 million for the Diagnostic Products segment, and $3.1 billion for the Vascular Products segment. Other than the effects of the separation of AbbVie, there were no reductions of goodwill relating to the disposal of all or a portion of a business. There was no reduction of goodwill relating to impairments.
The gross amount of amortizable intangible assets, primarily product rights and technology was $12.2 billion and $17.6 billion as of December 31, 2013 and 2012, respectively, and accumulated amortization was $6.8 billion and $9.7 billion as of December 31, 2013 and 2012, respectively. Indefinite-lived intangible assets, which relate to in-process research and development acquired in a business combination, were approximately $266 million and $691 million at December 31, 2013 and 2012, respectively. Gross amortizable intangible assets, accumulated amortization and indefinite-lived intangible assets of $5.7 billion, $3.8 billion and $417 million, respectively, were transferred to AbbVie as part of the separation on January 1, 2013. In 2012 and 2011, Abbott recorded impairment charges of $69 million and $125 million, respectively, for certain research and development assets due to changes in the projected development and regulatory timelines for the projects. The charges relate to non-reportable segments. Discounted cash flow analysis was used to analyze fair value and the charges are included in research and development expenses.
The estimated annual amortization expense for intangible assets recorded at December 31, 2013 is approximately $711 million in 2014, $652 million in 2015, $636 million in 2016, $635 million in 2017 and $505 million in 2018. Amortizable intangible assets are amortized over 2 to 20 years (average 11 years).
