Amortization of finite-lived intangible assets is provided over their estimated useful lives ranging from 3 to 15 years on a straight-line basis.
Acquired product technology rights relate to the identifiable intangible assets acquired in connection with the 2002 Immunex Corporation acquisition, and the related amortization expense is included in Amortization of certain acquired intangible assets in the Consolidated Statements of Income. Acquired R&D technology rights, Other acquired intangible assets, IPR&D and Contract assets as of December 31, 2012 and 2011, included the identifiable intangible assets acquired in connection with the acquisitions of businesses that occurred during the years ended December 31, 2012 and 2011. (See Note 2, Business combinations.) Acquired R&D technology rights consist of technology used in R&D with alternative future uses and the related amortization expense is included in Research and development expense in the Consolidated Statements of Income. The amortization expense related to other acquired intangible assets is included principally in Cost of sales (excludes amortization of certain acquired intangible assets) and Selling, general and administrative expense in the Consolidated Statements of Income. During the years ended December 31, 2012, 2011 and 2010, we recognized amortization charges associated with our finite-lived intangible assets of $397 million, $380 million and $423 million, respectively. The total estimated amortization for each of the next five years for our intangible assets is $464 million, $446 million, $434 million, $413 million and $271 million in 2013, 2014, 2015, 2016 and 2017, respectively.
