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 $17.7 million of IPR&D costs to developed technology upon finalization of one of the projects. No projects were abandoned. The remaining IPR&D projects that make up the intangible asset balance as of December 31, 2013 are expected to be completed in early 2014.

Based on the carrying value of acquisition-related intangible assets, net as of December 31, 2013, the annual amortization expense for acquisition-related intangible assets, net is expected to be as follows:
