| Business Combination and Asset Acquisition [Abstract] | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Business Combinations | Business Combinations Acquisition of City Semiconductor, Inc. On May 13, 2020, the Company acquired certain assets and liabilities of City Semiconductor, Inc. (“City Semi”), which had developed technology related to analog and mixed-signal integrated circuitry, with a focus on high-speed analog-to-digital converters and digital-to-analog intellectual property cores. The Company accounted for the acquisition as a business combination. The transaction costs associated with the acquisition were not material and were expensed as incurred. The acquisition date fair value of the consideration transferred for City Semi was approximately $2,029, which consisted of the following:
The maximum contingent consideration payable in connection with the acquisition is $2,000. The acquisition date fair value of the contingent consideration was determined based on the Company’s assessment of the probability of achieving the performance targets that ultimately obligate the Company to transfer additional consideration to the seller. The contingent consideration is comprised of two tranches. The first tranche is payable, up to a maximum of $500, upon the achievement of cash collection targets within twelve months of the acquisition, and this target was achieved in May 2021. The second tranche is payable, up to a maximum of $1,500 upon the shipment of a product incorporating the acquired developed technology. The fair value of any outstanding contingent consideration liabilities will be remeasured as of the end of each reporting period with any resulting remeasurement gains or losses recognized in the condensed consolidated statement of operations. The fair value of the first and second tranche contingent consideration liabilities was $500 and $1,000, respectively, as of June 30, 2021, and $500 and $900, respectively, as of December 31, 2020. The fair value of the first tranche contingent consideration liability is reflected in Other current liabilities within the condensed consolidated balance sheet and the fair value of the second tranche contingent consideration liability is reflected in Other long-term liabilities. In connection with this acquisition, the two existing employees of City Semi, including the founder and sole shareholder of City Semi, entered into employment agreements with the Company. As there is a service condition associated with these agreements, the related compensation expense is accounted for separately from the acquisition. The Company recognizes the related compensation expense as research and development expense in the condensed consolidated statement of operations on a straight-line basis over the requisite service period. The following table summarizes the fair values of assets acquired and liabilities assumed as of the date of acquisition:
The Company estimates that the useful life of the acquired developed technology intangible asset is seven years and the useful life of the acquired software license intangible asset is approximately one year, which represents the remaining duration of the software license. The excess of purchase consideration over the fair value of net assets acquired was recorded as goodwill, which is primarily attributed to the assembled workforce. None of the goodwill recognized is expected to be deductible for income tax purposes. There are no amounts of revenue or earnings of City Semi included in the Company’s condensed consolidated statement of operations for the three months ended March 31, 2021. The unaudited pro forma financial information shown below summarizes the combined results of operations for the Company and City Semi as if the closing of the acquisition had occurred on January 1, 2020.
The unaudited pro forma financial information includes adjustments that are directly attributable to the business combination and are factually supportable. The adjustments primarily reflect the amortization of acquired developed technology and compensation expense related to consideration to be transferred to the founder upon the second anniversary of his employment. The unaudited pro forma financial information is presented for illustrative purposes only and is not necessarily indicative of the operating results that would have been realized if the acquisition had taken place on January 1, 2020. On June 10, 2021, in connection with the closing of the Transaction, the Company paid $900 to redeem the Class H units previously issued.
