In-process research & development ("IPR&D") assets represent the fair value of incomplete research and development projects that had not reached technological feasibility as of the date of acquisition. In 2013, we capitalized IPR&D of $28.1 million related to the 2013 Acquisitions. Initially, these assets are classified as indefinite-lived intangible assets that are not subject to amortization. IPR&D assets related to projects that have been completed are transfered to the developed technology intangible asset to begin amortization, while IPR&D assets related to abandoned projects are impaired and expensed to Research and development expense in the consolidated statements of comprehensive income. Subsequent to the completion of the 2013 Acquisitions, we reclassified $6.9 million and $17.7 million of IPR&D costs to the developed technology intangible asset upon finalization of projects during 2014 and 2013, respectively. No projects were abandoned in 2014 or 2013. The remaining IPR&D project as of December 31, 2014 is expected to be completed in the third quarter of 2015.

Based on the carrying value of Acquisition-related intangible assets, net as of December 31, 2014, the annual amortization expense for Acquisition-related intangible assets, net is expected to be as follows:
