On July 30, 2018, we completed our acquisition of the patent licensing business of Technicolor, a worldwide technology leader in the media and entertainment sector (the "Technicolor Acquisition"). The Technicolor Acquisition included the acquisition by InterDigital of approximately 18,000 patents and applications, across a broad range of technologies, including approximately 3,000 worldwide video coding patents and applications. Refer to our 2018 Form 10-K for further information on the Technicolor Acquisition.

The Technicolor Acquisition met the definition of a business combination, and as such was accounted for using the acquisition method of accounting. We allocated the fair value of consideration transferred to identifiable assets acquired and liabilities assumed based on their estimated fair values as of the acquisition date. We recorded the excess of the fair value of consideration transferred over the net values of these assets and liabilities as goodwill.

The amount of revenue and earnings that would have been included in the Company’s condensed consolidated statement of income for the three and nine months ended September 30, 2018 had the acquisition date been January 1, 2017 are reflected in the table below. These amounts have been calculated after applying the Company's accounting policies and adjusting the results to reflect additional interest expense as well as amortization that would have been charged assuming the fair value adjustments to amortizable intangible assets had been recorded as of January 1, 2017. In addition, pro forma adjustments have been made to reflect the impact of the transaction-related costs discussed below. These unaudited pro forma

combined results of operations have been prepared for comparative purposes only, and they do not purport to be indicative of the results of operations that actually would have resulted had the acquisition occurred on the date indicated, or that may result in the future. The amounts in the table are unaudited (in thousands, except for per share data):

On May 31, 2019, we completed the acquisition of the Research & Innovation, or R&I, unit of Technicolor SA. The acquisition brought the Company’s research team to approximately 340 engineers in eight R&D offices worldwide, and expanded the Company’s research capabilities in video coding, Internet of Things ("IoT") and smart home, imaging sciences, augmented reality and virtual reality, and artificial intelligence and machine learning technologies. The R&I unit was the driving creative force behind the patent portfolio that was acquired in the Technicolor Acquisition discussed above.

The acquisition of the R&I unit met the definition of an asset acquisition and was accounted for using the cost accumulation and allocation model. There was no cash consideration for the acquisition. As consideration for the acquisition, the jointly funded R&D collaboration that was entered into as part of the Technicolor Acquisition was terminated. Technicolor will continue to fund research to be performed by the R&I unit for certain limited projects for a specified time period, subject to renewal. The Company also assumed certain employee-related liabilities, including obligations for certain defined benefit post-retirement plans for the acquired R&I unit employees, which are further discussed below. Additionally, Technicolor agreed to reduce its rights under the revenue-sharing arrangement entered into as part of the Technicolor Acquisition, as further discussed below.

The acquisition of the R&I unit resulted in a net gain of approximately $14.2 million in second quarter 2019, inclusive of the $20.5 million gain from the derecognition of the contingent consideration liability described below, all of which is included within “Other Income (Expense), Net” in the condensed consolidated statement of income.

The original revenue-sharing arrangement between the Company and Technicolor created a contingent consideration liability upon closing of the Technicolor Acquisition in third quarter 2018. Refer to our 2018 Form 10-K for further information on the initial contingent consideration liability which was accounted for at fair value each reporting period.

Under the amended revenue-sharing arrangement described above, Technicolor will now receive 42.5% of future cash receipts from new licensing efforts from the Madison Arrangement (as defined below) only, subject to certain conditions and hurdles, but will no longer receive revenue-sharing from other licensing efforts in the consumer electronics field outside of the Madison Arrangement. We determined that the initial contingent consideration liability from the Technicolor Acquisition was significantly modified in conjunction with the acquisition of the R&I unit, and, as such, the contingent consideration liability will now be accounted for under ASC 450 - Contingencies under the asset acquisition framework when the liability is deemed probable and estimable. Since the contingent consideration liability arising from the amended revenue-sharing arrangement was not probable and estimable as of the acquisition date, the carrying value of the previous contingent consideration liability was derecognized, which resulted in a $20.5 million gain during the nine months ended September 30, 2019 and is included within "Other Income (Expense), Net" in the condensed consolidated statement of income.

In connection with the Technicolor Acquisition and the acquisition of the R&I unit, we assumed certain defined benefit plans which are accounted for in accordance with ASC 715 - Compensation - Retirement Benefits. These plans include a retirement lump sum indemnity plan and jubilee plan, both of which provide benefit payments to employees based upon years of service and compensation levels. As of September 30, 2019, the combined accumulated projected benefit obligation related

In conjunction with the Technicolor Acquisition, effective July 30, 2018, we assumed Technicolor’s rights and obligations under a joint licensing program with Sony Corporation (“Sony”) relating to digital televisions and standalone computer display monitors, which commenced in 2015 and is referred to as the "Madison Arrangement." We also assumed Technicolor's role as sole licensing agent for the Madison Arrangement. As licensing agent, we are responsible for making decisions regarding the prosecution and maintenance of the combined patent portfolio and the licensing and enforcement of the combined patent portfolio in the field of use of digital TVs and computer display monitors on an exclusive basis during the specified term in exchange for an agent fee. The Madison Arrangement falls under the scope of ASC 808, Collaborative Arrangements (“ASC 808”). Refer to our 2018 Form 10-K for further information on the Madison Arrangement.

An affiliate of CPPIB Credit Investments Inc. ("CPPIB Credit"), a wholly owned subsidiary of Canada Pension Plan Investment Board, is a third-party investor in the Madison Arrangement. CPPIB Credit has made certain payments to Technicolor and Sony and has agreed to contribute cash to fund certain capital reserve obligations under the arrangement in exchange for a percentage of future revenues, specifically through September 11, 2030 in regard to the Technicolor patents.

Upon our assumption of Technicolor’s rights and obligations under the Madison Arrangement, our relationship with CPPIB Credit meets the criteria in ASC 470-10-25 - Sales of Future Revenues or Various Other Measures of Income (“ASC 470”), which relates to cash received from an investor in exchange for a specified percentage or amount of revenue or other measure of income of a particular product line, business segment, trademark, patent, or contractual right for a defined period. Under this guidance, we recognized the fair value of our contingent obligation to CPPIB Credit, as of the acquisition date, as long-term debt in our condensed consolidated balance sheet. This initial fair value measurement was based on the perspective of a market participant and included significant unobservable inputs which are classified as Level 3 inputs within the fair value hierarchy. The fair value of the long-term debt as of September 30, 2019 and December 31, 2018 is disclosed within Note 8. Our repayment obligations are contingent upon future royalty revenues generated from the Madison Arrangement and there are no minimum or maximum payments under the arrangement.

Under ASC 470, amounts recorded as debt are amortized under the interest method. At each reporting period, we will review the discounted expected future cash flows over the life of the obligation. The Company made an accounting policy election to utilize the catch-up method when there is a change in the estimated future cash flows, whereby we will adjust the carrying amount of the debt to the present value of the revised estimated future cash flows, discounted at the original effective interest rate, with a corresponding adjustment recognized as interest expense within “Interest Expense” in the condensed consolidated statements of income. The effective interest rate as of the acquisition date was approximately 14.5%. This rate represents the discount rate that equates the estimated future cash flows with the fair value of the debt as of the acquisition date, and is used to compute the amount of interest to be recognized each period based on the estimated life of the future revenue streams. During the three and nine months ended September 30, 2019, we recognized $0.7 million and $2.0 million, respectively, of interest expense related to this debt, which was included within “Interest Expense” in the condensed consolidated statements of income. Any future payments made to CPPIB Credit, or additional proceeds received from CPPIB Credit, will decrease or increase the long-term debt balance accordingly.

Under the Madison Arrangement, the parties reserve cash in bank accounts to fund our activities to manage the portfolios. These accounts are custodial accounts for which the funds are restricted for this purpose. Refer to Note 8, "Cash, Concentration of Credit Risk and Fair Value of Financial Instruments," for a reconciliation of total cash, cash equivalents and restricted cash as of September 30, 2019 and December 31, 2018 to the captions within the condensed consolidated balance sheets.

To receive consent from both Sony and CPPIB Credit to assume the rights and responsibilities of Technicolor under the Madison Arrangement, we committed to contributing cash to fund shortfalls in the Madison Arrangement, up to a maximum of $25.0 million, through 2020. A shortfall funding is only required in the scenario where the restricted cash is not sufficient to fund current obligations. In the event that we fund a shortfall, any surplus cash resulting from subsequent royalty receipts would be used to repay our shortfall funding plus 25% interest in advance of distributions of royalties to either Sony or CPPIB Credit, assuming they have not participated in the funding of the shortfall. As of September 30, 2019, we have not contributed any shortfall funding.

Transaction and integration related costs related to the above transactions for the three months ended September 30, 2019 and 2018 were $2.1 million and $5.4 million, respectively. Transaction and integration related costs related to the above transactions for the nine months ended September 30, 2019 and 2018 were $6.9 million and $9.2 million, respectively. The majority of these costs were recorded within “Patent administration and licensing” and “Selling, general and administrative” expenses in the condensed consolidated statements of income.
