As of March 31, 2020, licenses at cost include an Orascovery license of $0.4 million, licenses purchased from Gland Pharma Limited (“Gland”) of $4.4 million, a license purchased from MAIA Pharmaceuticals, Inc. (“MAIA”) for $4.0 million, and licenses of other specialty products of $0.7 million. The Orascovery license with Hanmi Pharmaceuticals Co. Ltd. (“Hanmi”) was purchased directly from Hanmi and is being amortized on a straight-line basis over a period of 12.75 years, the remaining life of the license agreement at the time of purchase. The licenses purchased from Gland are being amortized on a straight-line basis over a period of 5 years, the remaining life of the license agreement at the time of purchase. The license purchased from MAIA is being amortized over a period of 7 years, the remaining life of the license agreement at the time of purchase.

The remaining intangible assets were acquired in connection with the acquisitions of Polymed Therapeutics, Inc. (“Polymed”) and Comprehensive Drug Enterprises (“CDE”). Intangible assets are amortized using an economic consumption model over their useful lives. The Polymed customer list and technology are amortized on a straight-line basis over 6 and 12 years, respectively. The CDE in-process research and development, (“IPR&D”), will not be amortized until the related projects are completed. IPR&D will be tested annually for impairment, unless conditions exist causing an earlier impairment test (e.g., abandonment of project). The Company recorded no impairments of IPR&D during the three months ended March 31, 2020. The weighted-average useful life for all intangible assets was 7.7 years as of March 31, 2020.

The Company recorded $0.5 million of amortization expense for both the three-month periods ended March 31, 2020 and 2019.

The Company’s goodwill balance is the result of prior period acquisitions and is allocated to the Global Supply Chain Platform reporting unit and the Oncology Innovation Platform reporting unit. Changes in goodwill balances are due to the effect of foreign currency on goodwill from acquisitions of subsidiaries that have a functional currency other than USD.
