Acquisitions | Acquisitions AptoVision Technologies Inc. On July 1, 2017, the Company acquired AptoVision Technologies Inc. ("AptoVision"), a privately-held provider of uncompressed, zero-frame latency, video-over-IP solutions addressing the professional audio visual ("Pro AV") market. The unique combination of AptoVision's advanced algorithms for real-time, full bandwidth video transmission over IP networks, and Semtech's industry leading high-speed signal integrity and chip development expertise is expected to enable the adoption of Software Defined Video over Ethernet ("SDVoE") accelerating this natural progression in the evolution of video transport. Under the terms of the share purchase agreement, the Company acquired all of the outstanding equity interest in AptoVision for a cash payment of $17.6 million at closing, net of acquired cash, and a commitment to pay additional contingent consideration of up to a maximum of $47.0 million over three years if certain goals are achieved in each of the earn out periods. The fair value of the additional contingent consideration (the "AptoVision Earn-out") as of the acquisition date was $17.0 million, of which $8.5 million is presented within "Accrued liabilities" and $8.5 million is presented within "Other long-term liabilities" in the Balance Sheets. For the nine months ended October 29, 2017, acquisition related transaction costs of $1.6 million are accounted for as an expense in the period in which the costs are incurred and are presented within "Selling, general and administrative" expense in the Statements of Income. AptoVision met the definition of a business and is accounted for under the acquisition method of accounting in accordance with the FASB’s ASC Topic 805, Business Combinations. The consideration to acquire AptoVision was allocated to the acquired tangible and intangible assets and assumed liabilities of AptoVision based on their respective estimated fair values as of the acquisition date. A summary of the allocation is as follows:
(in thousands) | Estimated Useful Life |  | October 29, 2017
Finite-lived intangible asset - Developed Technology | 6-7 years |  | $ | 20,000 |
Finite-lived intangible asset - Customer Relationships | 3 years |  | 4,000 |
Indefinite-lived intangible asset - in-process research and development ("IPR&D") |  |  | 2,300 |
Goodwill |  |  | 12,187 |
Other (liabilities) assets, net |  |  | (3,868 | )
Total consideration |  |  | $ | 34,619 |
The fair value of the developed technology rights acquired was determined by estimating the probability-weighted net cash flows attributable to these rights discounted to present value using a discount rate that represents the estimated rate that market participants would use to value this intangible asset. The developed technology rights acquired relate to AptoVision’s BlueRiver™ platform. The fair value of the customer relationships was determined by estimating the amount that would be required currently to replace the customers from lead generations to product shipment. The IPR&D primarily relates to an assumed license agreement that had been executed in close proximity to the acquisition date. The investment in the license approximates fair value. The $12.2 million excess of the acquisition consideration over the fair value of the assets acquired and liabilities assumed was allocated to goodwill. The goodwill resulted from expected synergies and other benefits from the transaction. The Company expects that all such goodwill will be deductible for tax purposes. The purchase price allocation for the AptoVision acquisition is complete and resulted in a reduction of goodwill during the three months ended October 29, 2017 of $4.7 million due primarily to tax related items. The adjustments did not have a material effect on the Company’s consolidated financial results. Net revenues and earnings attributable to AptoVision since the acquisition date were not material. Pro forma results of operations have not been presented as AptoVision’s annual financial results are not material to the Company’s consolidated financial results. Triune Systems, L.L.C On March 4, 2015, the Company acquired Triune Systems, L.L.C. ("Triune"), a privately-held supplier of isolated switching, wireless charging and power management platforms targeted at, among other things, high and low power, high efficiency applications. Under the terms of the purchase agreement, the Company acquired all of the outstanding equity interest in Triune for a guaranteed minimum purchase price of $45.0 million consisting of $35.0 million in cash paid at closing, with an additional cash consideration of $10.0 million of which $9.5 million was paid in September 2015 and $0.5 million was paid in the second quarter of fiscal year 2017. Subject to achieving certain future financial goals ("Triune Earn-out"), up to $70.0 million of contingent consideration will be paid over three years if certain net revenue targets are achieved starting in fiscal year 2016 and ending in fiscal year 2018. An additional payment of up to $16.0 million will be paid after fiscal year 2018 if certain cumulative net revenue and contribution margin targets are achieved. The Triune Earn-out targets for fiscal year 2017 were not met and the Company does not expect the fiscal year 2018 targets to be achieved. The fair value of the Triune Earn-out liability was zero as of both October 29, 2017 and January 29, 2017, respectively. (See Notes 6 and 11).
