Intangible assets acquired in the RondinX acquisition (see Note 5) were determined to be in-process R&D. In accordance with ASC 350-30-35-17A, R&D assets acquired in a business combination are considered an indefinite-lived intangible asset until completion or abandonment of the associated R&D efforts. Once the R&D efforts are complete, the Company will determine the useful life of the R&D assets and will amortize these assets accordingly in the financial statements. As of March 31, 2020, the in-process R&D efforts have been completed. The Company has determined the definite useful life of three years for the intangible asset. Amortization expenses recorded in the interim consolidated statements of operations were $379 thousand for the three months ended on March 31, 2020. Based on management's analysis, there was no impairment for the three months ended March 31, 2020 and 2019.
