INTERDIGITAL, INC. AND SUBSIDIARIES

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

March 31, 2016

(unaudited)

1.BASIS OF PRESENTATION

In the opinion of management, the accompanying unaudited, condensed consolidated financial statements contain all adjustments, consisting only of normal recurring adjustments, necessary for a fair statement of the financial position of InterDigital, Inc. (individually and/or collectively with its subsidiaries referred to as “InterDigital,” the “Company,” “we,” “us” or “our,” unless otherwise indicated) as of March 31, 2016, and the results of our operations for the three months ended March 31, 2016 and 2015 and our cash flows for the three months endedMarch 31, 2016 and 2015. The accompanying unaudited, condensed consolidated financial statements have been prepared in accordance with the instructions for Form 10-Q and, accordingly, do not include all of the detailed schedules, information and notes necessary to state fairly the financial condition, results of operations and cash flows in conformity with generally accepted accounting principles (“GAAP”). The year-end condensed consolidated balance sheet data was derived from audited financial statements, but does not include all disclosures required by GAAP for year-end financial statements. Therefore, these financial statements should be read in conjunction with the financial statements and notes thereto contained in the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2015 (our “2015 Form 10-K”) as filed with the Securities and Exchange Commission (“SEC”) on February 18, 2016. The results of operations for interim periods are not necessarily indicative of the results to be expected for the entire year. We have one reportable segment.

The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities as of the date of the financial statements, as well as the reported amounts of revenues and expenses during the reporting period. Actual results could differ from these estimates.

Change in Accounting Policies

There have been no material changes or updates in our existing accounting policies from the disclosures included in our 2015 Form 10-K except as stated below in "New Accounting Guidance."

New Accounting Guidance

Accounting Standards Update: Stock Compensation

In March 2016, the Financial Accounting Standards Board ("FASB") issued ASU No. 2016-09, "Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting." ASU 2016-09 simplifies several aspects of the accounting for employee share-based payment transactions for both public and nonpublic entities, including the accounting for income taxes, forfeitures, and statutory tax withholding requirements, as well as classification in the statement of cash flows. The guidance is effective for the interim and annual periods beginning on or after December 15, 2016. (Early adoption is permitted in any interim or annual period for which financial statements have not yet been issued or have not been made available for issuance. If early adoption is elected, all amendments in the ASU that apply must be adopted in the same period. In addition, if early adoption is elected in an interim period, any adjustments should be reflected as of the beginning of the annual period that includes that interim period.) We are currently evaluating the effect that adopting this guidance will have on the Company's financial position, results of operations or cash flows.

Accounting Standards Update: Consolidation

In February 2015, the FASB issued ASU No. 2015-2, “Consolidation (Topic 820): Amendments to the Consolidation Analysis.” ASU 2015-2 provides a revised consolidation model for all reporting entities to use in evaluating whether they should consolidate certain legal entities. All legal entities will be subject to reevaluation under this revised consolidation model. The revised consolidation model, among other things, (i) modifies the evaluation of whether limited partnerships and similar legal entities are voting interest entities, or VIEs, (ii) eliminates the presumption that a general partner should consolidate a limited partnership and (iii) modifies the consolidation analysis of reporting entities that are involved with VIEs through fee arrangements and related party relationships. ASU 2015-2 is effective for fiscal years, and interim reporting periods within those fiscal years, beginning after December 15, 2015. The amended standard has not impacted the Company's financial position or results of operations.     

Accounting Standards Update: Revenue Recognition

In May 2014, the FASB issued guidance on revenue from contracts with customers that will supersede most current revenue recognition guidance, including industry-specific guidance. On April 14, 2016, the FASB amended the guidance by issuing ASU 2016-10, "Revenue from Contracts with Customers (Topic 606): Identifying Performance Obligations and Licensing." The underlying principle is that an entity will recognize revenue to depict the transfer of goods or services to

7

customers at an amount that the entity expects to be entitled to in exchange for those goods or services. The guidance provides a five-step analysis of transactions to determine when and how revenue is recognized. Other major provisions include capitalization of certain contract costs, consideration of time value of money in the transaction price, and allowing estimates of variable consideration to be recognized before contingencies are resolved in certain circumstances. The guidance also requires enhanced disclosures regarding the nature, amount, timing and uncertainty of revenue and cash flows arising from an entity’s contracts with customers. The guidance is effective for the interim and annual periods beginning on or after December 15, 2017 (early adoption is permitted as of annual reporting periods beginning after December 15, 2016, including interim reporting periods within those annual periods). The guidance permits the use of either a retrospective or cumulative effect transition method. We have not yet selected a transition method. We are currently evaluating the effect that adopting this guidance will have on the Company's financial position, results of operations or cash flows.

2. SALE-LEASEBACK

During second quarter 2015, we sold our facility in King of Prussia, Pennsylvania, to a third party and entered into a limited leaseback arrangement for a period not to exceed one year, for net consideration of $4.5 million. The carrying amount of the assets to be sold is $1.1 million as of March 31, 2016, and is still included within Property and Equipment. The gain related to the sale will be recorded within Other Expense (Net) in our Consolidated Statements of Operations, and the assets sold will be removed from Property and Equipment, at the completion of the lease term in second quarter 2016.

3.INCOME TAXES

In first quarter 2016, our effective tax rate was approximately 34.1% as compared to 38.4% during first quarter 2015, based on the statutory federal tax rate net of discrete federal and state taxes. The decrease in our effective tax rate was primarily attributable to the inclusion of an estimated U.S. federal research and development tax credit and a partial reversal of a tax reserve in first quarter 2016. The U.S. federal research and development tax credit received a permanent extension in December 2015. In first quarter 2016, we reversed a portion of our tax reserve upon completion of the Joint Committee on Taxation's review of the U.S. tax audit for the tax years 2010 through 2012. Additionally, our first quarter 2015 effective tax rate included a higher level of certain deductions that were not allowed for tax purposes, contributing to the higher effective tax rate as compared to first quarter 2016.

During first quarter 2016 and 2015, we paid approximately $14.3 million and $12.3 million, respectively, of foreign source withholding tax. Additionally, as of March 31, 2016, included within our taxes payable and deferred tax asset balances was$13.4 million of foreign source withholding tax and the associated foreign tax credit that we expect to utilize to offset future U.S. federal income taxes. This balance is related to a receivable from foreign licensees.     

4.NET INCOME PER SHARE

Basic Earnings Per Share ("EPS") is calculated by dividing net income available to common shareholders by the weighted-average number of common shares outstanding for the period. Diluted EPS reflects the potential dilution that could occur if options or other securities with features that could result in the issuance of common stock were exercised or converted to common stock. The following tables reconcile the numerator and the denominator of the basic and diluted net income per share computation (in thousands, except for per share data):

	For the Three Months Ended March 31,
	2016					2015
	Basic		Diluted			Basic		Diluted
Numerator:
Net income applicable to InterDigital, Inc.	$	28,071	$	28,071		$	29,065	$	29,065
Denominator:
Weighted-average shares outstanding: Basic	35,045		35,045			36,954		36,954
Dilutive effect of stock options, RSUs, convertible securities and warrants			332					375
Weighted-average shares outstanding: Diluted			35,377					37,329
Earnings Per Share:
Net income: Basic	$	0.80	$	0.80		$	0.79	$	0.79
Dilutive effect of stock options, RSUs, convertible securities and warrants			(0.01		)			(0.01		)
Net income: Diluted			$	0.79				$	0.78

8

Certain shares of common stock issuable upon the exercise or conversion of certain securities have been excluded from our computation of earnings per share because the strike price or conversion rate, as applicable, of such securities was less than the average market price of our common stock for first quarter 2016 and first quarter 2015, as applicable, and, as a result, the effect of such exercise or conversion would have been anti-dilutive. Set forth below are the securities and the weighted average number of shares of common stock underlying such securities that were excluded from our computation of earnings per share for the periods presented (in thousands):

	For the Three Months Ended March 31,
	2016	2015
Restricted stock units and stock options	173	18
Convertible securities	7,724	5,100
Warrants	8,496	5,100
Total	16,393	10,218

5. LITIGATION AND LEGAL PROCEEDINGS

ARBITRATIONS AND COURT PROCEEDINGS (OTHER THAN DE DISTRICT COURT ACTIONS RELATED TO USITC PROCEEDINGS)

Huawei Arbitration

On December 23, 2013, InterDigital and Huawei agreed to engage in an expedited binding arbitration to resolve their licensing disputes. Pursuant to their agreement, on April 9, 2014, InterDigital and Huawei initiated an arbitration with the International Court of Arbitration of the International Chamber of Commerce (ICC) jointly seeking a determination by an arbitral tribunal of FRAND royalty terms and conditions to be included in a binding worldwide patent license agreement to take effect upon issuance of the arbitration award. An arbitration hearing was held on January 12-16, 2015. On May 26, 2015, the panel convened by the ICC delivered a confidential partial award. The panel convened by the ICC delivered a confidential final award dated July 14, 2015.

On June 9, 2015, InterDigital filed a petition in the United States District Court for the Southern District of New York (the “New York District Court”) for an order confirming the arbitration award (the “New York Proceeding”). On the same day, Huawei filed an action in the Paris Court of Appeal requesting annulment of the arbitration award (the “Paris Proceeding”).

On July 24, 2015, Huawei opposed InterDigital’s petition in the New York Proceeding and filed a motion to stay the New York Proceeding pending the Paris Proceeding. On August 14, 2015, InterDigital amended its petition in the New York Proceeding to take into account the issuance of the arbitration panel’s final award. A hearing in the New York Proceeding was held on February 16, 2016. On February 17, 2016, the judge notified the parties that he had rendered a decision on Huawei’s motion to stay the New York Proceeding, finding that the New York Proceeding should be stayed pending the Paris Proceeding, subject to a requirement that Huawei post suitable security, pursuant to Article VI of the New York Convention, in the amount of the final award, together with interest. The stay is subject to revision should circumstances change, and InterDigital can renew its petition for an order confirming the award following the outcome of the Paris Proceeding. On March 28, 2016, the New York District Court issued an order setting the amount of Huawei’s security.

Huawei filed its brief seeking annulment in the Paris Proceeding on July 24, 2015. A hearing in the Paris Proceeding was held on March 8, 2016. On April 12, 2016, the Paris Court of Appeal denied Huawei’s request to annul the arbitration award. Huawei has indicated that it is considering an appeal of the Paris Court of Appeal decision to the highest court in France. On April 26, 2016, the parties submitted a proposed order to the New York District Court, which was entered by the court that same day, notifying the court of their agreements regarding payments under the partial and final arbitration awards and the status of the New York Proceeding. As it considers whether to pursue an appeal of the Paris Court of Appeal decision, Huawei has agreed to make payments, without prejudice to its right to a further appeal, of amounts currently outstanding and amounts that become due under the arbitration awards (including the resulting license agreement). In addition, InterDigital has agreed not to seek to lift the stay in the New York Proceeding pending receipt of all such payments and pending any further appeal that Huawei has the right to pursue to the courts of France, and not to require Huawei to post security.

We expect the first payment under the arbitration awards and license agreement to be made in second quarter 2016. We will recognize the related revenue in the period in which all criteria for revenue recognition have been met.

Huawei China Proceedings

On February 21, 2012, InterDigital was served with two complaints filed by Huawei Technologies Co., Ltd. in the Shenzhen Intermediate People's Court in China on December 5, 2011. The first complaint named as defendants InterDigital, Inc. and its wholly owned subsidiaries InterDigital Technology Corporation and InterDigital Communications, LLC (now InterDigital Communications, Inc.), and alleged that InterDigital had abused its dominant market position in the market for the licensing of essential patents owned by InterDigital by engaging in allegedly unlawful practices, including differentiated pricing, tying and refusal to deal. The second complaint named as defendants the Company's wholly owned subsidiaries InterDigital Technology Corporation, InterDigital Communications, LLC (now InterDigital Communications, Inc.), InterDigital Patent Holdings, Inc. and IPR Licensing, Inc. and alleged that InterDigital had failed to negotiate on FRAND terms with Huawei. Huawei asked the court to determine the FRAND rate for licensing essential Chinese patents to Huawei and also sought compensation for its costs associated with this matter.

On February 4, 2013, the Shenzhen Intermediate People's Court issued rulings in the two proceedings. With respect to the first complaint, the court decided that InterDigital had violated the Chinese Anti-Monopoly Law by (i) making proposals for royalties from Huawei that the court believed were excessive, (ii) tying the licensing of essential patents to the licensing of non-essential patents, (iii) requesting as part of its licensing proposals that Huawei provide a grant-back of certain patent rights to InterDigital and (iv) commencing a USITC action against Huawei while still in discussions with Huawei for a license. Based on these findings, the court ordered InterDigital to cease the alleged excessive pricing and alleged improper bundling of InterDigital's Chinese essential and non-essential patents, and to pay Huawei 20.0 million RMB (approximately $3.2 million) in damages related to attorneys’ fees and other charges, without disclosing a factual basis for its determination of damages. The court dismissed Huawei's remaining allegations, including Huawei's claim that InterDigital improperly sought a worldwide license and improperly sought to bundle the licensing of essential patents on multiple generations of technologies. With respect to the second complaint, the court determined that, despite the fact that the FRAND requirement originates from ETSI's Intellectual Property Rights policy, which refers to French law, InterDigital's license offers to Huawei should be evaluated under Chinese law. Under Chinese law, the court concluded that the offers did not comply with FRAND. The court further ruled that the royalties to be paid by Huawei for InterDigital's 2G, 3G and 4G essential Chinese patents under Chinese law should not exceed 0.019% of the actual sales price of each Huawei product.

On March 11, 2013, InterDigital filed notices of appeal with respect to the judgments in both proceedings, seeking reversal of the court’s February 4, 2013 rulings. On October 16, 2013, the Guangdong Province High Court issued a ruling affirming the ruling of the Shenzhen Intermediate People's Court in the second proceeding, and on October 21, 2013, issued a ruling affirming the ruling of the Shenzhen Intermediate People's Court in the first proceeding.

InterDigital believes that the decisions are seriously flawed both legally and factually. For instance, in determining a purported FRAND rate, the Chinese courts applied an incorrect economic analysis by evaluating InterDigital’s lump-sum patent license agreement with Apple in hindsight to posit a running royalty rate. Indeed, the ALJ in USITC Inv. No. 337-TA-800 rejected that type of improper analysis. Moreover, the Chinese courts had an incomplete record and applied incorrect facts, including with respect to InterDigital’s now-expired license agreement with Apple, which had been found in an arbitration between InterDigital and Apple to be limited in scope.

On April 14, 2014, InterDigital filed a petition for retrial of the second proceeding with the Chinese Supreme People’s Court (“SPC”), seeking dismissal of the judgment or at least a higher, market-based royalty rate for a license to InterDigital’s Chinese standards-essential patents (“SEPs”).  The petition for retrial argues, for example, that (1) the lower court improperly determined a Chinese FRAND running royalty rate by using as a benchmark the Apple lump sum fixed payment license agreement, and looking in hindsight at the unexpectedly successful sales of Apple iPhones to construct an artificial running royalty rate that neither InterDigital nor Apple could have intended and that would have varied significantly depending on the relative success or failure in hindsight of Apple iPhone sales; (2) the Apple license agreement was also an inappropriate benchmark because its scope of product coverage was significantly limited as compared to the license that the court was considering for Huawei, particularly when there are other more comparable license agreements; and (3) if the appropriate benchmarks had been used, and the court had considered the range of royalties offered by other similarly situated SEP holders in the wireless telecommunications industry, the court would have determined a FRAND royalty that was substantially higher than 0.019%, and would have found, consistent with findings of the ALJ’s initial determination in the USITC 337-TA-800 proceeding, that there was no proof that InterDigital’s offers to Huawei violated its FRAND commitments.

The SPC held a hearing on October 31, 2014, regarding whether to grant a retrial and requested that both parties provide additional information regarding the facts and legal theories underlying the case. The SPC convened a second hearing on April 1, 2015 regarding whether to grant a retrial. If the retrial is granted, the SPC will likely schedule one or more additional hearings before it issues a decision on the merits of the case.

ZTE China Proceedings

On July 10 and 11, 2014, InterDigital was served with two complaints filed by ZTE Corporation in the Shenzhen Intermediate People's Court in China on April 3, 2014. The first complaint names as defendants the Company's wholly owned subsidiaries InterDigital Technology Corporation, InterDigital Communications, Inc., InterDigital Patent Holdings, Inc. and IPR Licensing, Inc. This complaint alleges that InterDigital has failed to comply with its FRAND obligations for the licensing of its Chinese standards-essential patents. ZTE is asking the court to determine the FRAND rate for licensing InterDigital’s standards-essential Chinese patents to ZTE and also seeks compensation for its litigation costs associated with this matter. The second complaint names as defendants InterDigital, Inc. and its wholly owned subsidiaries InterDigital Technology Corporation and InterDigital Communications, Inc. This complaint alleges that InterDigital has a dominant market position in China and the United States in the market for the licensing of essential patents owned by InterDigital, and abused its dominant market position in violation of the Chinese Anti-Monopoly Law by engaging in allegedly unlawful practices, including excessively high pricing, tying, discriminatory treatment, and imposing unreasonable trading conditions.  ZTE seeks relief in the amount of 20.0 million RMB (approximately $3.1 million based on the exchange rate as of March 31, 2016), an order requiring InterDigital to cease the allegedly unlawful conduct and compensation for its litigation costs associated with this matter.

On August 7, 2014, InterDigital filed petitions challenging the jurisdiction of the Shenzhen Intermediate People's Court to hear the actions. On August 28, 2014, the court denied InterDigital’s jurisdictional challenge with respect to the anti-monopoly law case. InterDigital filed an appeal of this decision on September 26, 2014. On September 28, 2014, the court denied InterDigital’s jurisdictional challenge with respect to the FRAND case, and InterDigital filed an appeal of that decision on October 27, 2014. On December 18, 2014, the Guangdong High Court issued decisions on both appeals upholding the Shenzhen Intermediate Court’s decisions that it had jurisdiction to hear these cases. On February 10, 2015, InterDigital filed a petition for retrial with the Supreme People’s Court regarding its jurisdictional challenges to both cases.

The Shenzhen Court held hearings on the anti-monopoly law case on May 11, 13, 15 and 18, 2015. At the May hearings, ZTE withdrew its claims alleging discriminatory treatment and the imposition of unfair trading conditions and increased its damages claim to 99.8 million RMB (approximately $15.4 million based on the exchange rate as of March 31, 2016). The Shenzhen Court held hearings in the FRAND case on July 29-31, 2015 and held a second hearing on the anti-monopoly law case on October 12, 2015. It is possible that the court may schedule further hearings in these cases before issuing its decisions.

The Company has not recorded any accrual at March 31, 2016 for contingent losses associated with these matters based on its belief that losses, while reasonably possible, are not probable in accordance with accounting guidance. Further, the possible range of loss, if any, cannot be reasonably estimated at this time.

LG Arbitration

On March 19, 2012, LG Electronics, Inc. filed a demand for arbitration against the Company’s wholly owned subsidiaries InterDigital Technology Corporation, IPR Licensing, Inc. and InterDigital Communications, LLC (now InterDigital Communications, Inc.) with the American Arbitration Association’s International Centre for Dispute Resolution (“ICDR”), initiating an arbitration in Washington, D.C. LG sought a declaration that it held a continuing license to certain technology owned by InterDigital under the parties’ patent license agreement dated January 1, 2006 (the “2006 LG PLA”). On April 18, 2012, InterDigital filed an Answering Statement objecting to the jurisdiction of the ICDR on the ground that LG’s claims are not arbitrable, and denying all claims made by LG in its demand for arbitration. The issue of whether LG’s claim to arbitrability is wholly groundless was appealed to the Federal Circuit. On June 7, 2013, the Federal Circuit issued an opinion holding that the USITC erred in terminating USITC Proceeding (337-TA-800) as to LG because “there is no plausible argument that the parties’ dispute in this case arose under their patent license agreement” and finding that “LG’s assertion of arbitrability was ‘wholly groundless.’” The Federal Circuit reversed the USITC’s order terminating the USITC proceeding as to LG and remanded to the USITC for further proceedings.

On June 25, 2013, the arbitration tribunal granted the parties’ joint request to stay the arbitration pending the exhaustion of all appellate rights from the Federal Circuit’s decision. As noted above, LG filed a petition for a writ of certiorari with the U.S. Supreme Court challenging the Federal Circuit’s ruling on December 31, 2013, and on April 21, 2014, the Supreme Court granted LG’s petition, vacating the underlying Federal Circuit decision and remanding the case to the Federal Circuit with instructions to dismiss the case as moot (in light of InterDigital’s decision to terminate the 337-TA-800 investigation as to LG).

On June 9, 2014, the arbitration tribunal lifted the temporary stay at the request of the parties. The arbitration tribunal held an evidentiary hearing on July 20-22, 2015 and a supplemental oral argument on October 19, 2015. On December 29,

11

2015, the arbitration tribunal issued its final award. Rejecting LG’s arguments, the arbitration tribunal found that LG’s license with respect to 3G products under the 2006 LG PLA had terminated as of December 31, 2010, at the expiration of the 2006 LG PLA’s five-year term, and that only LG’s paid-up license with respect to 2G-only products survived the expiration of the term. On February 5, 2016, InterDigital filed a petition in the New York District Court for an order confirming the arbitration award. On February 29, 2016, the New York District Court entered judgment on InterDigital’s petition to confirm the arbitration award.

Pegatron Actions

In first quarter 2015, we learned that on or about February 3, 2015, Pegatron Corporation (“Pegatron”), one of our licensees, filed a civil suit in Taiwan Intellectual Property Court against InterDigital, Inc. and certain of its subsidiaries alleging breach of the Taiwan Fair Trade Act (the “Pegatron Taiwan Action”). On May 26, 2015, InterDigital, Inc. received a copy of the civil complaint filed by Pegatron in the Taiwan Intellectual Property Court. The complaint named as defendants InterDigital, Inc. as well as InterDigital’s wholly owned subsidiaries InterDigital Technology Corporation and IPR Licensing, Inc. (together, for purposes of this discussion, “InterDigital”). The complaint alleged that InterDigital abused its market power by improperly setting, maintaining or changing the royalties Pegatron is required to pay under their 2008 patent license agreement (the “Pegatron PLA”), and engaging in unreasonable discriminatory treatment and other unfair competition activities in violation of the Taiwan Fair Trade Act. The complaint sought minimum damages in the amount of approximately $52 million, which amount could be expanded during the litigation, and that the court order multiple damages based on its claim that the alleged conduct was intentional. The complaint also sought an order requiring InterDigital to cease enforcing the royalty provisions of the Pegatron PLA, as well as all other conduct that allegedly violates the Fair Trade Act.

On June 5, 2015 InterDigital filed an Arbitration Demand with the American Arbitration Association’s International Centre for Dispute Resolution (“ICDR”) seeking declaratory relief denying all of the claims in Pegatron’s Taiwan Action and for breach of contract. On or about June 10, 2015, InterDigital filed a complaint in the United States District Court for the Northern District of California, San Jose Division (the “CA Northern District Court”) seeking a Temporary Restraining Order, Preliminary Injunction, and Permanent Anti-suit Injunction against Pegatron prohibiting Pegatron from prosecuting the Pegatron Taiwan Action. The complaint also seeks specific performance by Pegatron of the dispute resolution procedures set forth in the Pegatron PLA and compelling arbitration of the disputes in the Pegatron Taiwan Action. On June 29, 2015, the court granted InterDigital’s motion for a temporary restraining order and preliminary injunction requiring Pegatron take immediate steps to dismiss the Taiwan Action without prejudice. On July 1, 2015, InterDigital was informed that Pegatron had withdrawn its complaint in the Taiwan Intellectual Property Court and that the case had been dismissed without prejudice.

On August 3, 2015, Pegatron filed an answer and counterclaims to InterDigital’s CA Northern District Court complaint. Pegatron accused InterDigital of violating multiple sections of the Taiwan Fair Trade Act, violating Section Two of the Sherman Act, breaching ETSI, IEEE, and ITU contracts, promissory estoppel (pled in the alternative), violating Section 17200 of the California Business & Professions Code, and violating the Delaware Consumer Fraud Act. These counterclaims stem from Pegatron’s accusation that InterDigital violated FRAND obligations. As relief, Pegatron seeks a declaration regarding the appropriate FRAND terms and conditions for InterDigital’s “declared essential patents,” a declaration that InterDigital’s standard essential patents are unenforceable due to patent misuse, an order requiring InterDigital to grant Pegatron a license on FRAND terms, an order enjoining InterDigital’s alleged ongoing breaches of its FRAND commitments, and damages in the amount of allegedly excess non-FRAND royalties Pegatron has paid to InterDigital, plus interest and treble damages. On August 7, 2015, Pegatron responded to InterDigital’s arbitration demand, disputing the arbitrability of Pegatron’s claims. On September 24, 2015, InterDigital moved to compel arbitration and dismiss Pegatron’s counterclaims or, in the alternative, stay the counterclaims pending the parties’ arbitration. Pegatron’s opposition to this motion was filed on October 22, 2015, and InterDigital’s reply was filed on November 12, 2015. On January 20, 2016, the court granted InterDigital’s motion to compel arbitration of Pegatron’s counterclaims and to stay the counterclaims pending the arbitrators’ determination of their arbitrability. On January 27, 2016, the parties stipulated to stay all remaining aspects of the CA Northern District case pending such an arbitrability determination. On the same day, the court granted the stay and administratively closed the case. The arbitration remains pending.

Microsoft Sherman Act Delaware Proceedings

12

On August 20, 2015, Microsoft Mobile, Inc. and Microsoft Mobile Oy (collectively “Microsoft”) filed a complaint in the United States District Court for the District of Delaware (the “Delaware District Court”) against InterDigital, Inc., InterDigital Communications, Inc., InterDigital Technology Corporation, InterDigital Patent Holdings, Inc., InterDigital Holdings, Inc., and IPR Licensing, Inc. The complaint alleges that InterDigital has monopolized relevant markets for 3G and 4G cellular technology in violation of Section 2 of the Sherman Act. As relief, Microsoft seeks declaratory judgments that InterDigital has violated Section 2 of the Sherman Act, that “each of InterDigital’s U.S. patents declared by it to be Essential” to the 3G and 4G standards is unenforceable, and that all agreements InterDigital has entered into in furtherance of its alleged unlawful conduct are void. Microsoft also seeks an award of treble damages and the following injunctive relief: requiring InterDigital to grant Microsoft a non-confidential license to its U.S. standards essential patents (“SEPs”) on FRAND terms as determined by a court, requiring InterDigital to disclose to Microsoft the terms of its other SEP licenses, preventing InterDigital from enforcing any exclusion orders it might receive with respect to its SEPs, and requiring InterDigital to re-assign any declared SEPs that it has assigned to controlled entities.

On November 4, 2015, InterDigital filed a motion to dismiss and to strike Microsoft’s complaint. A hearing on this motion was held on March 1, 2016, and on April 13, 2016, the Delaware District Court denied InterDigital’s motion. On April 27, 2016, InterDigital filed a motion with the Delaware District Court to certify questions addressed in the court’s April 13, 2016 decision for interlocutory appeal.

Sharp Arbitration

On December 19, 2014, Sharp Corporation (“Sharp”) filed a demand for arbitration against the Company’s wholly owned subsidiary InterDigital Technology Corporation (“ITC”) with the American Arbitration Association’s International Center for Dispute Resolution.  Sharp’s demand for arbitration is based on ITC’s alleged breach of the August 10, 2001 patent license agreement (as amended) (the “2001 PLA”) between Sharp and ITC.  Sharp claims that ITC breached its FRAND commitments under the ETSI IPR policy, Section 6.1, by enforcing the 2001 PLA, thereby requiring Sharp to pay what it alleges to be excessive and discriminatory royalties.  Sharp also claims that ITC breached the implied covenant of good faith and fair dealing in the 2001 PLA by charging what Sharp alleges are excessive and discriminatory royalties. Sharp further alleges that ITC should be promissorily estopped from charging allegedly excessive and discriminatory royalties, and that ITC should provide an accounting of overpayments resulting from ITC’s alleged failure to observe its FRAND commitments.  Sharp is seeking (a) a declaration that ITC breached its FRAND commitments and breached the implied covenant of good faith and fair dealing, (b) calculation of new FRAND rates for the 2001 PLA, and (c) an order that ITC must return an amount to be determined for Sharp’s alleged overpayment under the 2001 PLA. Based on recent submissions by Sharp, we have reason to believe that Sharp may seek to amend its claims to allege that ITC breached a contractual provision that was included in the original 2001 PLA, prior to subsequent amendment. In addition, based on recent submissions by Sharp, we have reason to believe that Sharp may seek as damages a refund of a substantial majority of the royalties paid by Sharp under the 2001 PLA plus interest, resulting in an aggregate amount of damages of up to approximately $390 million. The arbitration is scheduled for an evidentiary hearing in July 2016.

The Company has not recorded any accrual at March 31, 2016 for contingent losses associated with this matter based on its belief that losses, while reasonably possible, are not probable in accordance with accounting guidance. Further, the possible range of loss, if any, cannot be reasonably estimated at this time.

REGULATORY PROCEEDINGS

Investigation by Taiwan Fair Trade Commission

On December 6, 2013, InterDigital received notice from the Taiwan Fair Trade Commission (“TFTC”) that the TFTC had initiated an investigation to examine alleged anti-competitive behavior under Taiwan’s Fair Trade Act (FTA). Companies found to violate the FTA may be ordered to cease and rectify the unlawful conduct, take other necessary corrective action, and/or pay an administrative fine. InterDigital is fully cooperating with the TFTC’s investigation.

Investigation by National Development and Reform Commission of China

On September 23, 2013, counsel for InterDigital was informed by China’s National Development and Reform Commission (“NDRC”) that the NDRC had initiated a formal investigation into whether InterDigital has violated China’s Anti-Monopoly Law (“AML”) with respect to practices related to the licensing of InterDigital’s standards-essential patents to Chinese companies. Companies found to violate the AML may be subject to a cease and desist order, fines and disgorgement of any illegal gains. On March 3, 2014, the Company submitted to NDRC, pursuant to a procedure set out in the AML, a formal application for suspension of the investigation that included proposed commitments by the Company. On May 22,

13

2014, NDRC formally suspended its investigation of the Company based on the commitments proposed by the Company. The Company’s commitments with respect to the licensing of its patent portfolio for wireless mobile standards to Chinese manufacturers of cellular terminal units (“Chinese Manufacturers”) are as follows:

1. Whenever InterDigital engages with a Chinese Manufacturer to license InterDigital’s patent portfolio for 2G, 3G and 4G wireless mobile standards, InterDigital will offer such Chinese Manufacturer the option of taking a worldwide portfolio license of only its standards-essential wireless patents, and comply with F/RAND principles when negotiating and entering into such licensing agreements with Chinese Manufacturers.

2.  As part of its licensing offer, InterDigital will not require that a Chinese Manufacturer agree to a royalty-free, reciprocal cross-license of such Chinese Manufacturer's similarly categorized standards-essential wireless patents.

3.  Prior to commencing any action against a Chinese Manufacturer in which InterDigital may seek exclusionary or injunctive relief for the infringement of any of its wireless standards-essential patents, InterDigital will offer such Chinese Manufacturer the option to enter into expedited binding arbitration under fair and reasonable procedures to resolve the royalty rate and other terms of a worldwide license under InterDigital's wireless standards-essential patents.  If the Chinese Manufacturer accepts InterDigital's binding arbitration offer or otherwise enters into an agreement with InterDigital on a binding arbitration mechanism, InterDigital will, in accordance with the terms of the arbitration agreement and patent license agreement, refrain from seeking exclusionary or injunctive relief against such company.

The commitments contained in item 3 above will expire five years from the effective date of the suspension of the investigation, or May 22, 2019.

USITC PROCEEDINGS AND RELATED DELAWARE DISTRICT COURT PROCEEDINGS

Nokia and ZTE 2013 USITC Proceeding (337-TA-868) and Related Delaware District Court Proceedings

USITC Proceeding (337-TA-868)

On January 2, 2013, the Company’s wholly owned subsidiaries InterDigital Communications, Inc., InterDigital Technology Corporation, IPR Licensing, Inc. and InterDigital Holdings, Inc. filed a complaint with the United States International Trade Commission (the “USITC” or “Commission”) against Samsung Electronics Co., Ltd., Samsung Electronics America, Inc. and Samsung Telecommunications America, LLC, Nokia Corporation and Nokia Inc., Huawei Technologies Co., Ltd., Huawei Device USA, Inc. and FutureWei Technologies, Inc. d/b/a Huawei Technologies (USA) and ZTE Corporation and ZTE (USA) Inc. (collectively, the “337-TA-868 Respondents”), alleging violations of Section 337 of the Tariff Act of 1930 in that they engaged in unfair trade practices by selling for importation into the United States, importing into the United States and/or selling after importation into the United States certain 3G and 4G wireless devices (including WCDMA-, cdma2000- and LTE-capable mobile phones, USB sticks, mobile hotspots, laptop computers and tablets and components of such devices) that infringe one or more of up to seven of InterDigital’s U.S. patents. The complaint also extended to certain WCDMA and cdma2000 devices incorporating Wi-Fi functionality. InterDigital’s complaint with the USITC sought an exclusion order that would bar from entry into the United States infringing 3G or 4G wireless devices (and components), including LTE devices, that are imported by or on behalf of the 337-TA-868 Respondents, and also sought a cease-and-desist order to bar further sales of infringing products that have already been imported into the United States. Certain of the asserted patents were also asserted against Nokia, Huawei and ZTE in earlier pending USITC proceedings (including the Nokia, Huawei and ZTE 2011 USITC Proceeding (337-TA-800) and the Nokia 2007 USITC Proceeding (337-TA-613), as set forth below) and therefore were not asserted against those 337-TA-868 Respondents in this investigation.

On December 23, 2013, InterDigital and Huawei reached a settlement agreement to enter into binding arbitration to resolve their global patent licensing disputes (see “Huawei Arbitration” above).  Pursuant to the settlement agreement, InterDigital and Huawei moved to dismiss all litigation matters pending between the parties except the action filed by Huawei in China to set a fair, reasonable and non-discriminatory (“FRAND”) rate for the licensing of InterDigital’s Chinese standards-essential patents (discussed above under “Huawei China Proceedings”), the decision in which InterDigital is permitted to further appeal. As a result, effective February 12, 2014, the Huawei Respondents were terminated from the 337-TA-868 investigation.

From February 10 to February 20, 2014, ALJ Essex presided over the evidentiary hearing in this investigation. The patents in issue in this investigation as of the hearing were U.S. Patent Nos. 7,190,966 (the “’966 patent”) and 7,286,847 (the “’847 patent”) asserted against ZTE and Samsung, and U.S. Patent No. 7,941,151 (the “’151 patent”) asserted against ZTE, Samsung and Nokia.

14

On June 3, 2014, InterDigital and Samsung filed a joint motion to terminate the investigation as to Samsung on the basis of settlement. The ALJ granted the joint motion by initial determination issued on June 9, 2014, and the USITC determined not to review the initial determination on June 30, 2014.

On June 13, 2014, the ALJ issued an Initial Determination (“ID”) in the 337-TA-868 investigation. In the ID, the ALJ found that no violation of Section 337 had occurred in connection with the importation of 3G/4G devices by ZTE or Nokia, on the basis that the accused devices do not infringe asserted claims 1-6, 8-9, 16-21 or 23-24 of the ’151 patent, claims 1, 3, 6, 8, 9, or 11 of the ’966 patent, or claims 3 or 5 of the ’847 patent. The ALJ also found that claim 16 of the ’151 patent was invalid as indefinite. Among other determinations, the ALJ further determined that InterDigital did not violate any FRAND obligations, a conclusion also reached by the ALJ in the 337-TA-800 investigation, and that Respondents have engaged in patent “hold out.”

On June 30, 2014, InterDigital filed a Petition for Review with the USITC seeking review and reversal of certain of the ALJ’s conclusions in the ID. On the same day, Respondents filed a Conditional Petition for Review urging alternative grounds for affirmance of the ID’s finding that Section 337 was not violated and a Conditional Petition for Review with respect to FRAND issues.

In June 2014, Microsoft Mobile Oy (“MMO”) was added as a respondent in the investigation.

On August 14, 2014, the Commission determined to review in part the June 13, 2014 ID but terminated the investigation with a finding of no violation.

On October 10, 2014, InterDigital filed a petition for review with the Federal Circuit, appealing certain of the adverse determinations in the Commission’s August 8, 2014 final determination including those related to the ’966 and ’847 patents. On June 2, 2015, InterDigital moved to voluntarily dismiss the Federal Circuit appeal, because, even if it were to prevail, it did not believe there would be sufficient time following the court’s decision and mandate for the USITC to complete its proceedings on remand such that the accused products would be excluded before the ’966 and ’847 patents expire in June 2016. The court granted the motion and dismissed the appeal on June 18, 2015.

Related Delaware District Court Proceedings

On January 2, 2013, the Company’s wholly owned subsidiaries InterDigital Communications, Inc., InterDigital Technology Corporation, IPR Licensing, Inc. and InterDigital Holdings, Inc. filed four related district court actions in the Delaware District Court against the 337-TA-868 Respondents. These complaints allege that each of the defendants infringes the same patents with respect to the same products alleged in the complaint filed by InterDigital in USITC Proceeding (337-TA-868). The complaints seek permanent injunctions and compensatory damages in an amount to be determined, as well as enhanced damages based on willful infringement, and recovery of reasonable attorneys’ fees and costs.

On January 24, 2013, Huawei filed its answer and counterclaims to InterDigital’s Delaware District Court complaint. Huawei asserted counterclaims for breach of contract, equitable estoppel, waiver of right to enjoin and declarations that InterDigital has not offered or granted Huawei licenses on FRAND terms, declarations seeking the determination of FRAND terms and declarations of noninfringement, invalidity and unenforceability of the asserted patents. In addition to the declaratory relief specified in its counterclaims, Huawei seeks specific performance of InterDigital’s purported contracts with Huawei and standards-setting organizations, appropriate damages in an amount to be determined at trial, reasonable attorneys’ fees and such other relief as the court may deem appropriate.

On January 31, 2013, ZTE filed its answer and counterclaims to InterDigital’s Delaware District Court complaint; ZTE asserted counterclaims for breach of contract, equitable estoppel, waiver of right to enjoin and declarations that InterDigital has not offered ZTE licenses on FRAND terms, declarations seeking the determination of FRAND terms and declarations of noninfringement, invalidity and unenforceability. In addition to the declaratory relief specified in its counterclaims, ZTE seeks specific performance of InterDigital's purported contracts with ZTE and standards-setting organizations, appropriate damages in an amount to be determined at trial, reasonable attorneys’ fees and such other relief as the court may deem appropriate.    

On February 28, 2013, Nokia filed its answer and counterclaims to InterDigital’s Delaware District Court complaint, and then amended its answer and counterclaims on March 5, 2013. Nokia asserted counterclaims for breach of contract, breach of implied contract, unfair competition under Cal. Bus. & Prof. Code § 17200, equitable estoppel, a declaration setting FRAND terms and conditions, a declaration that InterDigital is estopped from seeking an exclusion order based on its U.S. declared-essential patents, a declaration of patent misuse, a declaration that InterDigital has failed to offer FRAND terms, a declaration that Nokia has an implied license to the asserted patents, and declarations of non-infringement, invalidity and

15

unenforceability. In addition to the declaratory relief specified in its counterclaims, Nokia seeks an order that InterDigital specifically perform its purported contracts by not seeking a USITC exclusion order for its essential patents and by granting Nokia a license on FRAND terms and conditions, an injunction preventing InterDigital from participating in a USITC investigation based on essential patents, appropriate damages in an amount to be determined, including all attorney’s fees and costs spent in participating in all three USITC Investigations (337-TA-868, 337-TA-800 and 337-TA-613), and any other relief as the court may deem just and proper.

On March 13, 2013, InterDigital filed an amended Delaware District Court complaint against Nokia and Samsung, respectively, to assert allegations of infringement of the recently issued ’244 patent. On April 1, 2013, Nokia filed its answer and counterclaims to InterDigital’s amended Delaware District Court complaint. On April 24, 2013, Samsung filed its answer and a counterclaim to InterDigital’s amended Delaware District Court complaint.

On March 21, 2013, pursuant to stipulation, the Delaware District Court granted InterDigital leave to file an amended complaint against Huawei and ZTE, respectively, to assert allegations of infringement of the ’244 patent. On March 22, 2013, Huawei and ZTE filed their respective answers and counterclaims to InterDigital’s amended Delaware District Court complaint. On April 9, 2013, InterDigital filed a motion to dismiss Huawei’s and ZTE’s counterclaims relating to their FRAND allegations. On April 22, 2013, InterDigital filed a motion to dismiss Nokia’s counterclaims relating to its FRAND allegations. On July 12, 2013, the Delaware District Court held a hearing on InterDigital’s motions to dismiss. By order issued the same day, the Delaware District Court granted InterDigital’s motions, dismissing counterclaims for equitable estoppel, implied license, waiver of the right to injunction or exclusionary relief, and violation of California Bus. & Prof. Code § 17200 with prejudice. It further dismissed the counterclaims for breach of contract and declaratory relief related to InterDigital’s FRAND commitments with leave to amend.

On August 6, 2013, Huawei, Nokia, and ZTE filed answers and amended counterclaims for breach of contract and for declaratory judgments seeking determination of FRAND terms. The counterclaims also continue to seek declarations of noninfringement, invalidity, and unenforceability. Nokia also continued to assert a counterclaim for a declaration of patent misuse. On August 30, 2013, InterDigital filed a motion to dismiss the declaratory judgment counterclaims relating to the request for determination of FRAND terms. On May 28, 2014, the court granted InterDigital’s motion and dismissed defendants’ FRAND-related declaratory judgment counterclaims, ruling that such declaratory judgments would serve no useful purpose.

On December 30, 2013, InterDigital and Huawei filed a stipulation of dismissal on account of the confidential settlement agreement and agreement to arbitrate their disputes in this action. On the same day, the Delaware District Court granted the stipulation of dismissal.

On February 11, 2014, the Delaware District Court judge entered an InterDigital, Nokia, and ZTE stipulated Amended Scheduling Order that bifurcated issues relating to damages, FRAND-related affirmative defenses, and any FRAND-related counterclaims.

On August 28, 2014, the court granted in part a motion by InterDigital for summary judgment that the asserted ’151 patent is not unenforceable by reason of inequitable conduct, holding that only one of the references forming the basis of defendants’ allegations would remain in issue, and granted a motion by InterDigital for summary judgment that the asserted claims of the ’966 and ’847 patents are not invalid for lack of enablement.

On August 5, 2014, InterDigital and Samsung filed a stipulation of dismissal in light of the parties’ settlement agreement. On the same day, the court granted the stipulation of dismissal and dismissed the action with prejudice.

By order dated August 28, 2014, MMO was joined in the case as a defendant.

The ZTE trial addressing infringement and validity of the ’966, ’847, ’244 and ’151 patents was held from October 20 to October 27, 2014. During the trial, the judge determined that further construction of certain claim language of the ’151 patent was required, and the judge decided to hold another trial as to ZTE's infringement of the ’151 patent at a later date. On October 28, 2014, the jury returned a unanimous verdict in favor of InterDigital, finding that the ’966, ’847 and ’244 patents are all valid and infringed by ZTE 3G and 4G cellular devices. The court issued formal judgment to this effect on October 29, 2014.

On November 26, 2014, ZTE filed a motion for judgment as a matter of law that the asserted claims of the ’966, ’847 and ’244 patents are not infringed and, in the alternative, for a new trial. InterDigital filed an opposition on December 15, 2014, and ZTE filed a reply on January 7, 2015.

16

The ZTE trial addressing infringement of the ’151 patent was held from April 20 to April 22, 2015. On April 22, 2015, the jury returned a verdict in favor of ZTE, finding that the ’151 patent is not infringed by ZTE 3G and 4G cellular devices.

On April 23, 2015, InterDigital filed a motion to partially dismiss its complaint pertaining to the ’151 patent against Nokia and MMO, as well as Nokia and MMO’s counterclaims that relate to the ’151 patent (including inequitable conduct), and on April 27, 2015, the judge granted the motion.

On April 27, 2015, the court ruled that Nokia Corporation should be severed for a separate trial addressing infringement of the ’244 patent.

On May 5, 2015, the court scheduled the Nokia Inc./MMO jury trial addressing infringement of the ’244 patent for November 16, 2015. On May 29, 2015, the court entered a new scheduling order for damages and FRAND-related issues due to changes in the schedule of the liability portion of the MMO proceedings, scheduling trials related to damages and FRAND-related issues for October 2016 with ZTE and November 2016 with MMO.

On September 14, 2015, a panel of Administrative Law Judges of the United States Patent and Trademark Office Patent Trial and Appeal Board (the “PTAB”) issued a final written decision in two Inter Partes Review (“IPR”) cases concerning the ’244 patent. These IPR proceedings were commenced on petitions filed by ZTE Corporation and ZTE (USA) Inc. and by Microsoft Corporation, respectively. Specifically, the panel determined that a number of claims of the ’244 patent are unpatentable as obvious. IPR Licensing, Inc. appealed to the U.S. Court of Appeals for the Federal Circuit seeking review of the PTAB’s decision. The appeals are pending. On October 13, 2015, by stipulation of the parties, the Delaware District Court stayed the action involving MMO and Nokia Inc., including the November 2015 and November 2016 trials concerning infringement of the ’244 patent and damages and FRAND-related issues, respectively, pending completion of the IPR proceedings, including all appeals and subsequent proceedings before the PTAB. This stay is with respect to MMO and Nokia Inc. only, and does not apply to the Delaware action pending against ZTE.

On May 12, 2015, Nokia/MMO moved for summary judgment of non-infringement of the ’244 patent, alleging that the accused devices do not practice a particular claim element of the ’244 patent. On June 2, 2015, InterDigital opposed Nokia/MMO’s motion, and filed a cross-motion for partial summary judgment that the accused devices infringe the claim element at issue in Nokia/MMO’s motion for summary judgment. On October 13, 2015, the Delaware District Court denied the pending summary judgment cross-motions without prejudice in light of the stay discussed above, indicating that the motions could be considered refiled if and when the stay is lifted if either party requests it.

On December 21, 2015, the court entered another scheduling order that vacated the October 2016 date for the ZTE trial related to damages and FRAND-related issues as set forth in the May 2015 scheduling order.

On March 18, 2016, the court denied ZTE’s motion for judgment as a matter of law, or in the alternative for a new trial, with respect to the ’966 and ’847 patents. The court postponed its ruling on ZTE’s motion as to the ’244 patent pending the U.S. Court of Appeals for the Federal Circuit’s decision on InterDigital’s appeal of the September 14, 2015 PTAB ruling and administratively closed that portion of the motion. On April 8, 2016, the court set a new schedule for the FRAND/damages portion of the ZTE case with a target trial date in February 2018.

On April 18, 2016, ZTE filed a stipulated request for dismissal with prejudice of its counterclaims for breach of contract and patent unenforceability based on FRAND and withdrew its corresponding FRAND-related affirmative defenses. Also on April 18, 2016, ZTE filed a motion under Federal Rule of Civil Procedure 54(b) seeking certification of partial final judgment on the claims for infringement of the ’966 and ’847 patents to allow ZTE to file an immediate appeal as to those patents. The motion is pending.

Nokia and ZTE 2011 USITC Proceeding (337-TA-800) and Related Delaware District Court Proceeding

USITC Proceeding (337-TA-800)

On July 26, 2011, InterDigital’s wholly owned subsidiaries InterDigital Communications, LLC (now InterDigital Communications, Inc.), InterDigital Technology Corporation and IPR Licensing, Inc. filed a complaint with the USITC against Nokia Corporation and Nokia Inc., Huawei Technologies Co., Ltd. and FutureWei Technologies, Inc. d/b/a Huawei Technologies (USA) and ZTE Corporation and ZTE (USA) Inc. (collectively, the “337-TA-800 Respondents”), alleging violations of Section 337 of the Tariff Act of 1930 in that they engaged in unfair trade practices by selling for importation into the United States, importing into the United States and/or selling after importation into the United States certain 3G wireless devices (including WCDMA- and cdma2000-capable mobile phones, USB sticks, mobile hotspots and tablets and components

17

of such devices) that infringe several of InterDigital’s U.S. patents. The action also extended to certain WCDMA and cdma2000 devices incorporating WiFi functionality. InterDigital’s complaint with the USITC sought an exclusion order that would bar from entry into the United States any infringing 3G wireless devices (and components) that are imported by or on behalf of the 337-TA-800 Respondents, and also sought a cease-and-desist order to bar further sales of infringing products that have already been imported into the United States. In May 2012, Huawei Device USA, Inc. was added as a 337-TA-800 Respondent.

The ALJ held an evidentiary hearing from February 12-21, 2013. The patents in issue as of the hearing were U.S. Patent Nos. 8,009,636 (the “’636 patent”), 7,706, 830 (the “’830 patent”), 7,502,406 (the “’406 patent”), 7,616,970 (the “’970 patent”), 7,706,332 (the “’332 patent”), 7,536,013 (the “’013 patent”) and 7,970,127 (the “’127 patent”). The ALJ’s Initial Determination (“ID”) issued on June 28, 2013, finding no violation because the asserted patents were not infringed and/or invalid. Among other determinations, with respect to the 337-TA-800 Respondents’ FRAND and other equitable defenses, the ALJ found that Respondents had failed to prove either that InterDigital violated any FRAND obligations, that InterDigital failed to negotiate in good faith, or that InterDigital’s licensing offers were discriminatory. The ALJ also found that InterDigital is not precluded from seeking injunctive relief based on any alleged FRAND commitments.

Petitions for review of the ID to the Commission were filed by InterDigital and the 337-TA-800 Respondents on July 15, 2013. On September 4, 2013, the Commission determined to review the ID in its entirety.

On December 19, 2013, the Commission issued its final determination. The Commission adopted, with some modification, the ALJ’s finding of no violation of Section 337 as to Nokia, Huawei, and ZTE. The Commission did not rule on any other issue, including FRAND and domestic industry, and stated that all other issues remain under review.

On December 20, 2013, InterDigital filed in the Federal Circuit a petition for review seeking reversal of the Commission’s final determination. On February 18, 2015, the Federal Circuit issued a decision affirming the USITC’s determinations that the claims of the ’830, ’636, ’406 and ’332 patents were not infringed, that the claims of the ’970 patent are invalid, and that the Respondents did not violate Section 337. On April 6, 2015, InterDigital filed a combined petition for panel rehearing and rehearing en banc as to the ’830 and ’636 patents. The petition was denied on May 12, 2015, and the court’s mandate issued on May 19, 2015.

Related Delaware District Court Proceeding

On July 26, 2011, the same date that InterDigital filed USITC Proceeding (337-TA-800), it filed a parallel action in the United States District Court for the District of Delaware against the 337-TA-800 Respondents alleging infringement of the same asserted patents identified in USITC Proceeding (337-TA-800). The Delaware District Court complaint seeks a permanent injunction and compensatory damages in an amount to be determined, as well as enhanced damages based on willful infringement, and recovery of reasonable attorneys' fees and costs. On September 23, 2011, the defendants in the Delaware District Court complaint filed a motion to stay the Delaware District Court action pending the parallel proceedings in the USITC. Because the USITC has instituted USITC Proceeding (337-TA-800), the defendants have a statutory right to a mandatory stay of the Delaware District Court proceeding pending a final determination in the USITC. On October 3, 2011, InterDigital amended the Delaware District Court complaint, adding LG as a defendant and adding the same additional patent that InterDigital requested be added to USITC Proceeding (337-TA-800). On October 11, 2011, the Delaware District Court granted the defendants' motion to stay. The case is currently stayed through June 15, 2016.

On January 14, 2014, InterDigital and Huawei filed a stipulation of dismissal of their disputes in this action on account of the confidential settlement agreement mentioned above. On the same day, the Delaware District Court granted the stipulation of dismissal.

Nokia 2007 USITC Proceeding (337-TA-613), Related Delaware District Court Proceeding and Federal Circuit Appeal

USITC Proceeding (337-TA-613)

In August 2007, InterDigital filed a USITC complaint against Nokia Corporation and Nokia, Inc., alleging a violation of Section 337 of the Tariff Act of 1930 in that Nokia engaged in an unfair trade practice by selling for importation into the United States, importing into the United States and/or selling after importation into the United States certain 3G mobile handsets and components that infringe two of InterDigital’s patents. In November and December 2007, respectively, a third patent and a fourth patent were added to the Company’s complaint against Nokia. The complaint sought an exclusion order barring from entry into the United States infringing 3G mobile handsets and components that are imported by or on behalf of Nokia. InterDigital’s complaint also sought a cease-and-desist order to bar further sales of infringing Nokia products that have already been imported into the United States.

18

On August 14, 2009, the ALJ overseeing USITC Proceeding (337-TA-613) issued an Initial Determination finding no violation of Section 337 of the Tariff Act of 1930. The Initial Determination found that InterDigital’s patents were valid and enforceable, but that Nokia did not infringe these patents. In the event that a Section 337 violation were to be found by the Commission, the ALJ recommended the issuance of a limited exclusion order barring entry into the United States of infringing Nokia 3G WCDMA handsets and components, as well as the issuance of appropriate cease-and-desist orders.

On October 16, 2009, the Commission issued a notice that it had determined to review in part the Initial Determination, and that it affirmed the ALJ’s determination of no violation and terminated the investigation. The Commission determined to review the claim construction of the patent claim terms “synchronize” and “access signal” and also determined to review the ALJ’s validity determinations. On review, the Commission modified the ALJ’s claim construction of “access signal” and took no position with regard to the claim term “synchronize” or the validity determinations. The Commission determined not to review the remaining issues decided in the Initial Determination.

On November 30, 2009, InterDigital filed with the Federal Circuit a petition for review of certain rulings by the USITC. In its appeal, InterDigital sought reversal of the Commission’s claim constructions and non-infringement findings with respect to certain claim terms in the ’966 and ’847 patents, vacatur of the Commission’s determination of no Section 337 violation and a remand for further proceedings before the Commission. On August 1, 2012, the Federal Circuit issued its decision in the appeal, holding that the Commission had erred in interpreting the claim terms at issue and reversing the Commission’s finding of non-infringement. The Federal Circuit adopted InterDigital’s interpretation of such claim terms and remanded the case back to the Commission for further proceedings. In addition, the Federal Circuit rejected Nokia’s argument that InterDigital did not satisfy the domestic industry requirement. On September 17, 2012, Nokia filed a combined petition for rehearing by the panel or en banc with the Federal Circuit. On January 10, 2013, the Federal Circuit denied Nokia’s petition.

On January 17, 2013, the Federal Circuit issued its mandate remanding USITC Proceeding (337-TA-613) to the Commission for further proceedings. On February 12, 2014, the Commission issued a notice, order and opinion remanding the investigation to an ALJ. In doing so, the Commission determined certain issues and identified others that would be subject to further proceedings by the ALJ. The Commission assigned the investigation to an ALJ for limited remand proceedings consistent with its February 12, 2014 opinion.

In June 2014, MMO was added as a respondent in the investigation.    

The evidentiary hearing in the remand proceeding was held January 26 - 28, 2015. On April 27, 2015, the ALJ issued his Remand Initial Determination (“RID”). The ALJ found that the imported accused handsets (1) contain chips that were not previously adjudicated and (2) infringe the asserted claims of the ’966 and ’847 patents, that there was no evidence of patent hold-up by InterDigital, that there is evidence of reverse hold-up by the respondents, and that the public interest does not preclude issuance of an exclusion order.

On May 11, 2015, Nokia Corporation and MMO each filed petitions to the Commission to review the RID. On June 25, 2015, the Commission issued a notice of its decision to review the RID in part. The Commission determined to review the RID’s findings concerning the application of the Commission’s prior construction of one claim limitation in Investigation Nos. 337-TA-800 and 337-TA-868, the RID’s findings as to whether the accused products satisfy that claim limitation, and the RID’s public interest findings. The Commission issued its final determination on August 28, 2015, finding that issue preclusion applied with respect to the construction of the claim limitations at issue, and issue preclusion also required a finding of non-infringement. The Commission determined there was no violation of Section 337 and terminated the 337-TA-613 investigation. The Commission found that consideration of the public interest issues was moot and did not address them.

Related Delaware District Court Proceeding

In addition, in August 2007, on the same date as the filing of USITC Proceeding (337-TA-613), InterDigital also filed a complaint in the Delaware District Court alleging that Nokia’s 3G mobile handsets and components infringe the same two InterDigital patents identified in the original USITC complaint. The complaint seeks a permanent injunction and damages in an amount to be determined. This Delaware action was stayed on January 10, 2008, pursuant to the mandatory, statutory stay of parallel district court proceedings at the request of a respondent in a USITC investigation. The Delaware District Court permitted InterDigital to add to the stayed Delaware action the third and fourth patents InterDigital asserted against Nokia in the USITC action. This case remains stayed.

In June 2014, we announced that our Board of Directors had approved a 100% increase in the Company’s quarterly cash dividend, to $0.20 per share. We currently expect to continue to pay dividends comparable to our quarterly $0.20 per share cash dividend in the future; however, continued payment of cash dividends and changes in the Company's dividend policy will depend on the Company's earnings, financial condition, capital resources and capital requirements, alternative uses of capital, restrictions imposed by any existing debt, economic conditions and other factors considered relevant by our Board of Directors.

Common Stock Warrants

On March 29, 2011 and March 30, 2011, we sold warrants to acquire, subject to customary anti-dilution adjustments, approximately 3.5 million and approximately 0.5 million shares of our common stock, respectively. The warrants become exercisable and expire in tranches over an approximately two-month period starting June 15, 2016, and have a strike price of $63.18 per share. In consideration for the warrants issued on March 29, 2011 and March 30, 2011, we received $27.6 million and $4.1 million, respectively, on April 4, 2011.

On March 5 and March 9, 2015, we sold warrants to acquire, subject to customary anti-dilution adjustments, approximately 3.8 million and approximately 0.6 million shares of our common stock, respectively, at an initial strike price of approximately $88.46 per share. The warrants become exercisable and expire in tranches over a three and a half month period starting in June 2020. As consideration for the warrants issued on March 5 and March 9, 2015, we received approximately $37.3 million and approximately $5.6 million, respectively.

7.CONCENTRATION OF CREDIT RISK AND FAIR VALUE OF FINANCIAL ASSETS AND FINANCIAL LIABILITIES

Concentration of Credit Risk and Fair Value of Financial Instruments

Financial instruments that potentially subject us to concentration of credit risk consist primarily of cash equivalents, short-term investments, and accounts receivable. We place our cash equivalents and short-term investments only in highly rated financial instruments and in United States government instruments.

Our accounts receivable are derived principally from patent license and technology solutions agreements. At March 31, 2016 and December 31, 2015, five licensees comprised 98% and four licensees comprised 97%, respectively, of our net accounts receivable balance. We perform ongoing credit evaluations of our licensees, who generally include large, multinational, wireless telecommunications equipment manufacturers. We believe that the book values of our financial instruments approximate their fair values.

Fair Value Measurements

Effective January 1, 2008, we adopted the provisions of the FASB fair value measurement guidance that relate to our financial assets and financial liabilities. We adopted the guidance related to non-financial assets and liabilities as of January 1, 2009. We use various valuation techniques and assumptions when measuring fair value of our assets and liabilities. We utilize market data or assumptions that market participants would use in pricing the asset or liability, including assumptions about risk and the risks inherent in the inputs to the valuation technique. This guidance established a hierarchy that prioritizes fair value

21

measurements based on the types of input used for the various valuation techniques (market approach, income approach and cost approach). The levels of the hierarchy are described below:

Level 1 Inputs — Level 1 includes financial instruments for which quoted market prices for identical instruments are available in active markets.

Level 2 Inputs — Level 2 includes financial instruments for which there are inputs other than quoted prices included within Level 1 that are observable for the instrument such as quoted prices for similar instruments in active markets, quoted prices for identical or similar instruments in markets with insufficient volume or infrequent transactions (less active markets) or model-driven valuations in which significant inputs are observable or can be derived principally from, or corroborated by, observable market data, including market interest rate curves, referenced credit spreads and pre-payment rates.

Level 3 Inputs — Level 3 includes financial instruments for which fair value is derived from valuation techniques including pricing models and discounted cash flow models in which one or more significant inputs are unobservable, including the Company’s own assumptions. The pricing models incorporate transaction details such as contractual terms, maturity and, in certain instances, timing and amount of future cash flows, as well as assumptions related to liquidity and credit valuation adjustments of marketplace participants.

Our assessment of the significance of a particular input to the fair value measurement requires judgment and may affect the valuation of financial assets and financial liabilities and their placement within the fair value hierarchy. We use quoted market prices for similar assets to estimate the fair value of our Level 2 investments. Our financial assets are included within short-term investments on our condensed consolidated balance sheets, unless otherwise indicated. Our financial assets that are accounted for at fair value on a recurring basis are presented in the tables below as of March 31, 2016 and December 31, 2015 (in thousands):

The aggregate fair value of the principal amount of the long-term debt (Level 2 Notes as defined in Note 8 “Long-Term Debt”) was calculated using inputs such as actual trade data, benchmark yields, broker/dealer quotes and other similar data, which were obtained from independent pricing vendors, quoted market prices or other sources.

8. LONG-TERM DEBT

2016 Senior Convertible Notes, and related Note Hedge and Warrant Transactions

In April 2011, we issued $230.0 million in aggregate principal amount of 2.50% Senior Convertible Notes due 2016 (the “2016 Notes”), which matured and were repaid in full on March 15, 2016.

In connection with the offering of the 2016 Notes, on March 29 and March 30, 2011, we entered into convertible note hedge transactions that covered, subject to customary anti-dilution adjustments, approximately 3.5 million and approximately 0.5 million shares of our common stock, respectively, at an initial strike price that corresponded to the initial conversion price of the 2016 Notes and were exercisable upon conversion of the 2016 Notes. In addition, on the same dates, we sold warrants to acquire, subject to customary anti-dilution adjustments, approximately 3.5 million shares and approximately 0.5 million shares, respectively, of common stock. The warrants have a current strike price of $63.18 per share, as adjusted as of January 11, 2016 in connection with a conversion rate adjustment to the 2016 Notes pursuant to the terms of the indenture for such notes. The warrants become exercisable and expire in tranches over an approximately two-month period starting June 15, 2016.

Accounting Treatment of the 2016 Notes and related Convertible Note Hedge and Warrant Transactions

The offering of the 2016 Notes on March 29, 2011 was for $200.0 million and included an overallotment option that allowed the initial purchaser to purchase up to an additional $30.0 million aggregate principal amount of 2016 Notes. The initial purchaser exercised its overallotment option on March 30, 2011, bringing the total amount of 2016 Notes issued on April 4, 2011 to $230.0 million.

In connection with the offering of the 2016 Notes, as discussed above, the Company entered into convertible note hedge transactions with respect to its common stock. The $42.7 million cost of the convertible note hedge transactions was partially offset by the proceeds from the sale of the warrants described above, resulting in a net cost of $10.9 million.

Existing accounting guidance provides that the March 29, 2011 convertible note hedge and warrant contracts be treated as derivative instruments for the period during which the initial purchaser's overallotment option was outstanding. Once the overallotment option was exercised on March 30, 2011, the March 29, 2011 convertible note hedge and warrant contracts were reclassified to equity, as the settlement terms of the Company's note hedge and warrant contracts both provide for net share settlement. There was no material net change in the value of these convertible note hedges and warrants during the one day they were classified as derivatives and the equity components of these instruments will not be adjusted for subsequent changes in fair value.

Under current accounting guidance, the Company bifurcated the proceeds from the offering of the 2016 Notes between the liability and equity components of the debt. On the date of issuance, the liability and equity components were calculated to be approximately $187.0 million and $43.0 million, respectively. The initial $187.0 million liability component was determined based on the fair value of similar debt instruments excluding the conversion feature. The initial $43.0 million ($28.0 million net of tax) equity component represents the difference between the fair value of the initial $187.0 million in debt and the $230.0 million of gross proceeds. The related initial debt discount of $43.0 million is being amortized using the effective interest method over the life of the 2016 Notes. An effective interest rate of 7% was used to calculate the debt discount on the 2016 Notes.

In connection with the above-noted transactions, the Company incurred $8.0 million of directly related costs. The initial purchaser's transaction fees and related offering expenses were allocated to the liability and equity components of the debt in proportion to the allocation of proceeds and accounted for as debt issuance costs. We allocated $6.5 million of debt issuance costs to the liability component of the debt, which were capitalized as deferred financing costs. These costs are being amortized to interest expense over the term of the debt using the effective interest method. The remaining $1.5 million of costs allocated to the equity component of the debt were recorded as a reduction of the equity component of the debt.

On March 11, 2015, we issued $316.0 million in aggregate principal amount of 1.50% Senior Convertible Notes due 2020 (the “2020 Notes”). The 2020 Notes bear interest at a rate of 1.50% per year, payable in cash on March 1 and September 1 of each year, commencing September 1, 2015, and mature on March 1, 2020, unless earlier converted or repurchased.

The 2020 Notes will be convertible into cash, shares of our common stock or a combination thereof, at our election, at an initial conversion rate of 13.8172 shares of common stock per $1,000 principal amount of 2020 Notes (which is equivalent to an initial conversion price of approximately $72.37 per share). It is our current intent and policy to settle all conversions through combination settlement of cash and shares of common stock, with a specified dollar amount of $1,000 per $1,000 principal amount of the 2020 Notes and any remaining amounts in shares.

Prior to 5:00 p.m., New York City time, on the business day immediately preceding December 1, 2019, the 2020 Notes will be convertible only under certain circumstances as set forth in the indenture to the 2020 Notes. Commencing on December 1, 2019, the 2020 Notes will be convertible in multiples of $1,000 principal amount, at any time prior to 5:00 p.m., New York City time, on the second scheduled trading day immediately preceding the maturity date of the 2020 Notes.

The Company may not redeem the 2020 Notes prior to their maturity date.

On March 5 and March 9, 2015, in connection with the offering of the 2020 Notes, we entered into convertible note hedge transactions that cover approximately 3.8 million and approximately 0.6 million shares of our common stock, respectively, at a strike price that corresponds initially to the initial conversion price of the 2020 Notes and are exercisable upon conversion of the 2020 Notes.

The cost of the March 5 and March 9, 2015 convertible note hedge transactions was approximately $51.7 million and approximately $7.7 million, respectively.

On March 5 and March 9, 2015, we sold warrants to acquire, subject to customary anti-dilution adjustments, approximately 3.8 million and approximately 0.6 million, respectively, of common stock at an initial strike price of approximately $88.46 per share. The warrants become exercisable and expire in tranches over a three and a half month period starting in June 2020. As consideration for the warrants issued on March 5 and March 9, 2015, we received approximately $37.3 million and approximately $5.6 million, respectively.

The Company also repurchased 0.8 million shares of our common stock at $53.61 per share, the closing price of the stock on March 5, 2015, from institutional investors through one of the initial purchasers and its affiliate, as our agent, concurrently with the pricing of the offering of the 2020 Notes.    

Accounting Treatment of the 2020 Notes and related Convertible Note Hedge and Warrant Transactions

The offering of the 2020 Notes on March 5, 2015 was for $275.0 million and included an overallotment option that allowed the initial purchasers to purchase up to an additional $41.0 million aggregate principal amount of 2020 Notes. The initial purchasers exercised their overallotment option on March 9, 2015, bringing the total amount of 2020 Notes issued on March 11, 2015 to $316.0 million.

In connection with the offering of the 2020 Notes, as discussed above, InterDigital entered into convertible note hedge transactions with respect to its common stock. The $59.4 million cost of the convertible note hedge transactions was partially offset by the proceeds from the sale of the warrants described above, resulting in a net cost of $16.5 million. Both the convertible note hedge and warrants were classified as equity.

The Company bifurcated the proceeds from the offering of the 2020 Notes between liability and equity components. On the date of issuance, the liability and equity components were calculated to be approximately $256.7 million and $59.3 million, respectively. The initial $256.7 million liability component was determined based on the fair value of similar debt instruments excluding the conversion feature. The initial $59.3 million ($38.6 million net of tax) equity component represents the difference between the fair value of the initial $256.7 million in debt and the $316.0 million of gross proceeds. The related initial debt discount of $59.3 million is being amortized using the effective interest method over the life of the 2020 Notes. An effective interest rate of 5.89% was used to calculate the debt discount on the 2020 Notes.

In connection with the above-noted transactions, the Company incurred $9.3 million of directly related costs. The initial purchasers' transaction fees and related offering expenses were allocated to the liability and equity components in proportion to the allocation of proceeds and accounted for as debt and equity issuance costs, respectively. We allocated $7.0 million of debt issuance costs to the liability component, which were capitalized as deferred financing costs. These costs are being amortized to interest expense over the term of the debt using the effective interest method. The remaining $2.4 million of costs allocated to the equity component were recorded as a reduction of the equity component.

The following table reflects the carrying value of the Company's convertible debt as of March 31, 2016 and December 31, 2015 (in thousands):

9. VARIABLE INTEREST ENTITIES

As further discussed below, we are the primary beneficiary of two variable interest entities. As of March 31, 2016, the combined book values of the assets and liabilities associated with these variable interest entities included in our Consolidated Balance Sheet were $22.9 million and $1.0 million, respectively. Assets included $16.5 million of cash and cash equivalents and $6.4 million of patents, net. As of December 31, 2015, the combined book values of the assets and liabilities associated with these variable interest entities included in our Consolidated Balance Sheet were $24.2 million and $0.8 million, respectively. Assets included $19.0 million of cash and cash equivalents and $5.2 million of patents, net. The impact of consolidating these variable interest entities on our Consolidated Statements of Income was not significant.

Convida Wireless

On September 26, 2015, we renewed and expanded our joint venture with Sony, Convida Wireless, to include 5G technologies. Convida Wireless was launched in 2013 to combine Sony's consumer electronics expertise with our pioneering Internet of Things (“IoT”) expertise to drive IoT communications and connectivity.  Based on the terms of the agreement, the parties will contribute funding and resources for additional research and platform development, which we will perform.  SCP IP Investment LLC, an affiliate of Stephens Inc., is a minority investor in Convida Wireless.

Convida Wireless is a variable interest entity. Based on our provision of research and platform development services to Convida Wireless, we have determined that we remain the primary beneficiary for accounting purposes and will continue to consolidate Convida Wireless.  For the three months ended March 31, 2016 and 2015, we have allocated approximately $0.9 million and $0.7 million, respectively, of Convida Wireless' net loss to noncontrolling interests held by other parties.

Signal Trust for Wireless Innovation

On October 17, 2013, we announced the establishment of the Signal Trust for Wireless Innovation (the “Signal Trust”), the goal of which is to monetize a large InterDigital patent portfolio related to cellular infrastructure.

The more than 500 patents and patent applications transferred from InterDigital to the Signal Trust focus primarily on 3G and LTE technologies, and were developed by InterDigital's engineers and researchers over more than a decade, with a number of the innovations contributed to the worldwide standards process.

InterDigital is the primary beneficiary of the Signal Trust. The distributions from the Signal Trust will support continued research related to cellular wireless technologies.  A small portion of the proceeds from the Signal Trust will be used to fund, through the Signal Foundation for Wireless Innovation, scholarly analysis of intellectual property rights and the technological, commercial and creative innovations they facilitate.

25

    The Signal Trust is a variable interest entity. Based on the terms of the Trust Agreement, we have determined that we are the primary beneficiary for accounting purposes and must consolidate the Signal Trust.

Item 2.MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS.

OVERVIEW

The following discussion should be read in conjunction with the unaudited, condensed consolidated financial statements and notes thereto contained in Part I, Item 1 of this Quarterly Report on Form 10-Q, in addition to our 2015 Form 10-K, other reports filed with the SEC and the Statement Pursuant to the Private Securities Litigation Reform Act of 1995 — Forward-Looking Statements below.

Throughout the following discussion and elsewhere in this Form 10-Q, we refer to “recurring revenues” and “past sales.”  Recurring revenues are comprised of “current patent royalties” and “current technology solutions revenue.”  Past sales are comprised of “past patent royalties” and “past technology solutions revenue.”

Recurring Revenue

Recurring revenue of $103.6 million in first quarter 2016 increased $11.0 million from $92.6 million in fourth quarter 2015 due to an increase in per-unit royalties primarily attributable to an increase in shipments from third quarter 2015 to fourth quarter 2015 by Pegatron Corporation (“Pegatron”) and our other Taiwan-based licensees.

Refer to “Results of Operations — First Quarter 2016 Compared to First Quarter 2015” for further discussion of our 2016 revenue.

Stock Repurchase

During first quarter 2016, we repurchased 0.9 million shares of common stock for $40.4 million. From April 1, 2016 through April 27, 2016, we repurchased an additional 0.1 million shares at a cost of $5.3 million, bringing the total number of shares repurchased under the company’s current $400 million stock repurchase program to 6.4 million shares at a cost of $294.8 million.

New Agreements and Other Past Sales

During first quarter 2016, we amended our worldwide, non-exclusive, royalty bearing patent license agreement with NEC Corporation (“NEC”). The agreement was amended to add coverage for 4G technologies, and NEC is now also licensed for the sale of its LTE and LTE-A terminal unit and infrastructure products.  The amendment also extends the existing term of NEC’s patent license with InterDigital. During first quarter 2016, we recognized $0.1 million of past sales and $0.9 million of fixed-fee royalty revenue related to this agreement.

Additionally, during first quarter 2016, we resolved an outstanding dispute with an existing licensee, and, as a result, recognized $3.9 million of past sales and $0.3 million of interest income.

Huawei Arbitration

In December 2013, InterDigital and Huawei reached a settlement agreement to enter into binding arbitration to resolve their global patent licensing dispute. Pursuant to their agreement, InterDigital and Huawei initiated an arbitration in April 2014 jointly seeking a determination by an arbitral tribunal of FRAND royalty terms and conditions to be included in a binding worldwide patent license agreement to take effect upon issuance of the arbitration award. An arbitration hearing was held in January 2015, and the arbitration panel delivered a confidential partial award in May 2015 and a confidential final award in July 2015. In June 2015, InterDigital filed a petition in the District Court for the Southern District of New York for an order confirming the arbitration award (the “New York Proceeding”), and Huawei filed an action in the Paris Court of Appeal requesting annulment of the arbitration award (the “Paris Proceeding”). Huawei also filed a motion to stay the New York Proceeding pending the Paris Proceeding. In February 2016, the judge in the New York Proceeding agreed to the stay, subject to the requirement that Huawei post suitable security, and in March 2016, the court issued an order setting the amount of Huawei’s security. A hearing was held in the Paris Proceeding in March 2016, and on April 12, 2016, the Paris Court of Appeal denied Huawei’s request to annul the arbitration award. Huawei has indicated that it is considering an appeal of the Paris Court of Appeal decision to the highest court in France. On April 26, 2016, the parties submitted a proposed order to the New York District Court, which was entered by the court that same day, notifying the court of their agreements regarding payments under the partial and final arbitration awards and the status of the New York Proceeding. As it considers whether to pursue an appeal of the Paris Court of Appeal decision, Huawei has agreed to make payments, without prejudice to its right to a further appeal, of amounts currently outstanding and amounts that become due under the arbitration awards (including the resulting license agreement). In addition, InterDigital has agreed not to seek to lift the stay in the New York Proceeding pending receipt of all

27

such payments and pending any further appeal that Huawei has the right to pursue to the courts of France, and not to require Huawei to post security.

We expect the first payment under the arbitration awards and license agreement to be made in second quarter 2016. We will recognize the related revenue in the period in which all criteria for revenue recognition have been met.

Please see Note 5,“Litigation and Legal Proceedings,” in the Notes to Condensed Consolidated Financial Statements included in Part I, Item 1 of this Quarterly Report on Form 10-Q for a more complete discussion of these proceedings.

Comparability of Financial Results

When comparing first quarter 2016 financial results against other periods, the following items should be taken into consideration:

• $4.1 million of past sales primarily related to the resolution of a dispute with an existing licensee;

• $1.9 million severance charge related to ongoing efforts to optimize our cost structure;

• $3.0 million of expense to increase accrual rates for some of our incentive compensation plans; and

• $0.6 million tax benefit as a result of a partial reversal of a tax reserve.

CRITICAL ACCOUNTING POLICIES AND ESTIMATES

Our significant accounting policies are described in Note 1 of the Notes to Consolidated Financial Statements included in our 2015 Form 10-K. A discussion of our critical accounting policies, and the estimates related to them, are included in Management’s Discussion and Analysis of Financial Condition and Results of Operations in our 2015 Form 10-K. There have been no material changes in our existing critical accounting policies from the disclosures included in our 2015 Form 10-K. Refer to Note 1, “Basis of Presentation,” in the Notes to Condensed Consolidated Financial Statements included in Part I, Item 1 of this Quarterly Report on Form 10-Q for updates related to new accounting pronouncements.

FINANCIAL POSITION, LIQUIDITY AND CAPITAL RESOURCES

Our primary sources of liquidity are cash, cash equivalents and short-term investments, as well as cash generated from operations. We believe we have the ability to obtain additional liquidity through debt and equity financings. Based on our past performance and current expectations, we believe our available sources of funds, including cash, cash equivalents and short-term investments and cash generated from our operations, will be sufficient to finance our operations, capital requirements, our debt obligations, existing stock repurchase program and dividend program for the next twelve months.

Cash, cash equivalents and short-term investments

At March 31, 2016 and December 31, 2015, we had the following amounts of cash, cash equivalents and short-term investments (in thousands):

	March 31, 2016		December 31, 2015		Increase / (Decrease)
Cash and cash equivalents	$	524,307	$	510,207	$	14,100
Short-term investments	134,387		423,501		(289,114		)
Total cash and cash equivalents and short-term investments	$	658,694	$	933,708	$	(275,014	)

The decrease in cash, cash equivalents and short-term investments was primarily attributable to the repayment of the $230.0 million aggregate principal amount of our 2.50% senior convertible notes (the “2016 Notes”) that became due in March 2016, capitalized patent costs and patent acquisitions of $12.6 million, share repurchases of $40.4 million and dividend payments of $7.1 million. These decreases were partially offset by $16.2 million of cash provided by operating activities.

Cash flows from operations

We generated the following cash flows from our operating activities in first quarter 2016 and 2015 (in thousands):

	For the Three Months Ended March 31,
	2016		2015		Increase / (Decrease)
Net cash provided by operating activities	$	16,233	$	1,771	$	14,462

28

Our cash flows provided by operating activities are principally derived from cash receipts from patent license and technology solutions agreements offset by cash operating expenses and income tax payments. The increase in cash flows provided by operating activities of $14.5 million was primarily attributable to an increase in cash receipts of $7.2 million and a decrease in cash outflows of $2.9 million. The increase in cash receipts was primarily attributable to higher current royalty cash receipts as a result of increased shipments by Pegatron and other Taiwan-based licensees. Cash operating expense decreased $4.6 million, which was partially offset by a $1.7 million increase in taxes paid. Other working capital adjustments increased $4.3 million, primarily due to timing differences in accounts payable. The table below provides the significant items comprising our cash flows provided by operating activities during the three months ended March 31, 2016 and 2015 (in thousands).

	For the Three Months Ended March 31,
	2016			2015			Increase / (Decrease)
Cash Receipts:
Current royalties a	$	76,478		$	70,717		$	5,761
Fixed-fee royalty payments	19,000			17,250			1,750
Prepaid royalties	3,356			2,390			966
Technology solutions	1,077			2,321			(1,244		)
Total cash receipts	$	99,911		$	92,678		$	7,233
Cash Outflows:
Cash operating expenses b	39,889			44,516			(4,627		)
Income taxes paid c	14,423			12,714			1,709
Total cash outflows	54,312			57,230			(2,918		)
Other working capital adjustments	(29,366		)	(33,677		)	4,311
Cash flows provided by operating activities	$	16,233		$	1,771		$	14,462

(a) Current patent royalty payments for the three months ended March 31, 2016 include $4.2 million of cash receipts recognized as past sales revenue.

(b) Cash operating expenses include operating expenses less depreciation of fixed assets, amortization of patents, and non-cash compensation.

(c) Income taxes paid include foreign withholding taxes.

Working capital

We believe that working capital, adjusted to exclude cash, cash equivalents, short-term investments and current deferred revenue provides additional information about non-cash assets and liabilities that might affect our near-term liquidity. While we believe cash and short-term investments are important measures of our liquidity, the remaining components of our current assets and current liabilities, with the exception of deferred revenue, could affect our near-term liquidity and/or cash flow. We have no material obligations associated with our deferred revenue, and the amortization of deferred revenue has no impact on our future liquidity and/or cash flow. Our adjusted working capital, a non-GAAP financial measure, reconciles to working capital, the most directly comparable GAAP financial measure, at March 31, 2016, and December 31, 2015 (in thousands), as follows:

29

	March 31, 2016		December 31, 2015			Increase / (Decrease)
Current assets	$	798,096	$	1,010,967		$	(212,871	)
Less: current liabilities	171,225		399,973			(228,748		)
Working capital	626,871		610,994			15,877
Subtract:
Cash and cash equivalents	524,307		510,207			14,100
Short-term investments	134,387		423,501			(289,114		)
Add:
Current deferred revenue	109,951		106,229			3,722
Adjusted working capital	$	78,128	$	(216,485	)	$	294,613

The $294.6 million net increase in adjusted working capital is primarily attributable to the repayment of the 2016 Notes, which resulted in a $227.2 million decrease in current liabilities. Additionally, accounts receivable increased $60.7 million due to the timing of payments related to both existing and new fixed-fee agreements.

Cash flows from investing and financing activities

We generated net cash in investing activities of $275.3 million and $22.1 million in first quarter 2016 and first quarter 2015, respectively. We sold$289.5 million and $51.4 million, net of purchases, of short-term marketable securities in first quarter 2016 and 2015, respectively. Investment costs associated with capitalized patent costs and acquisition of patents decreased to $12.6 million in first quarter 2016 from $28.4 million in first quarter 2015, primarily due to a final payment in first quarter 2015 of $20.0 million on a $45.0 million patent acquisition made in 2014. 

Net cash used in financing activities for first quarter 2016 was $277.5 million, a $512.3 million change from $234.8 million net cash generated in first quarter 2015. This change was primarily attributable to the $230.0 million repayment of the 2016 Notes in first quarter 2016 as compared to the $306.7 million in net proceeds from the issuance and sale of the 1.50% senior convertible notes due 2020 (the “2020 Notes”) in first quarter 2015. This change was partially offset by a $10.3 million decrease in repurchases of common stock in first quarter 2016 and $16.5 million of net costs for the bond hedge and warrant transactions entered into in first quarter 2015 in connection with the offering of the 2020 Notes.

Other

Our combined short-term and long-term deferred revenue balance at March 31, 2016 was approximately $441.1 million, an increase of $45.8 million from December 31, 2015. We have no material obligations associated with such deferred revenue. The increase was due to a gross increase in deferred revenue of $80.4 million associated with fixed-fee agreement payments or payments due within twelve months, which was partially offset by $34.6 million of deferred revenue recognized. The deferred revenue recognized was primarily comprised of $29.1 million of amortized fixed-fee royalty payments and $5.5 million in per-unit exhaustion of prepaid royalties.

Based on current license agreements, we expect the amortization of fixed-fee royalty payments to reduce the March 31, 2016 deferred revenue balance of $441.1 million by $110.0 million over the next twelve months. Additional reductions to deferred revenue will be dependent upon the level of per-unit royalties our licensees report against prepaid balances.

Revenues

The following table compares first quarter 2016 revenues to first quarter 2015 revenues (in thousands):

	For the Three Months Ended March 31,
	2016		2015		Increase/(Decrease)
Per-unit royalty revenue	$	73,689	$	75,583	$	(1,894	)	(3	)%
Fixed-fee amortized royalty revenue	29,098		33,373		(4,275		)	(13	)%
Current patent royalties a	102,787		108,956		(6,169		)	(6	)%
Past patent royalties b	4,167		17		4,150			NM
Total patent licensing royalties	106,954		108,973		(2,019		)	(2	)%
Current technology solutions revenue a	810		1,405		(595		)	(42	)%
Total revenue	$	107,764	$	110,378	$	(2,614	)	(2	)%

a.    Recurring revenues consist of current patent royalties and current technology solutions revenue.

b.    Past sales consist of past patent royalties and past technology solutions revenue.

The $2.6 milliondecrease in total revenue was primarily attributable to a $6.8 million decrease in recurring revenue. The decrease in recurring revenue was primarily a result of a $4.3 million decrease in fixed-fee amortized royalty revenue due to a lower base of fixed-fee amortized royalty revenue. The decrease in per-unit royalty revenue primarily resulted from decreased shipments by certain of our non-Taiwanese licensees. These decreases were partially offset by a $4.2 million increase in past sales. The increase in past sales was primarily driven by the resolution of a dispute with an existing licensee as discussed above. Current technology solutions revenue decreased by $0.6 million primarily due to decreased shipments by one of our technology solutions customers.

In first quarter 2016 and first quarter 2015, 62% and 55% of our total revenue, respectively, was attributable to companies that individually accounted for 10% or more of our total revenue. In first quarter 2016 and first quarter 2015, the following companies accounted for 10% or more of our total revenue:

	For the Three Months Ended March 31,
	2016	2015
Pegatron	46%	39%
Samsung	16%	16%

Operating Expenses

The following table summarizes the changes in operating expenses between first quarter 2016 and first quarter 2015 by category (in thousands):

	For the Three Months Ended March 31,
	2016		2015		Increase/ (Decrease)
Patent administration and licensing	$	27,167	$	31,625	$	(4,458	)	(14	)%
Development	20,269		17,991		2,278			13	%
Selling, general and administrative	11,972		9,518		2,454			26	%
Total operating expenses	$	59,408	$	59,134	$	274		—	%

Operating expenses increased slightly to $59.4 million in first quarter 2016 from $59.1 million in first quarter 2015. The $0.3 million increase in total operating expenses was primarily due to changes in the following items (in thousands):

31

	Increase/ (Decrease)
Performance-based incentive compensation	$	4,230
Personnel-related costs	2,187
Depreciation and amortization	1,233
Other	14
Intellectual property enforcement and non-patent litigation	(7,390		)
Total increase in operating expenses	$	274

The $4.2 million increase in performance-based incentive compensation was primarily driven by a $3.0 million non-recurring charge to increase accrual rates associated with our long-term performance-based compensation plans, following recent developments involving an arbitration award and related agreement that are expected to result in the collection of all amounts currently due to us under such award and agreement in second quarter 2016. The $2.2 million increase in personnel-related costs was primarily due to a non-recurring $1.9 million severance charge incurred during first quarter 2016 related to ongoing efforts to optimize our cost structure. Additionally, the $1.2 million increase in depreciation and amortization was primarily related to recent patent acquisitions. These increases and other increases were partially offset by the $7.4 million decrease in intellectual property enforcement and non-patent litigation primarily related to decreased costs associated with the USITC actions and licensee arbitrations.

Patent Administration and Licensing Expense: The decrease in patent administration and licensing expense primarily resulted from the above-noted decrease in intellectual property enforcement and non-patent litigation costs. The decrease was partially offset by the above-noted increases in performance-based incentive compensation and patent amortization.

Development Expense: The increase in development expense primarily resulted from the above-noted increases in performance-based incentive compensation and personnel-related costs.

Selling, General and Administrative Expense: The increase in selling, general and administrative expense primarily resulted from the above-noted increases in performance-based incentive compensation and personnel-related costs.

Other (Expense) Income

The following table compares first quarter 2016 other (expense) income to first quarter 2015 other (expense) income (in thousands):

	For the Three Months Ended March 31,
	2016			2015			Change
Interest expense	$	(8,185	)	$	(5,473	)	$	(2,712	)	50	%
Other	(112		)	(188		)	76			(40	)%
Interest and investment income	1,160			425			735			173	%
	$	(7,137	)	$	(5,236	)	$	(1,901	)	36	%

In first quarter 2016, other expense was $7.1 million as compared to other expense of $5.2 million in first quarter 2015. The change between periods was primarily due to additional interest expense as a result of the issuance of the 2020 Notes in first quarter 2015. This increase in other expense was partially offset by higher returns on our investment balances during first quarter 2016 as compared to first quarter 2015 and $0.3 million of interest income related to the resolution of a dispute with an existing licensee, as discussed above.

Income tax provision

In first quarter 2016, our effective tax rate was approximately 34.1% as compared to 38.4% during first quarter 2015, based on the statutory federal tax rate net of discrete federal and state taxes. The decrease in our effective tax rate is primarily attributable to the inclusion of an estimated U.S. federal research and development tax credit and a partial reversal of a tax reserve in first quarter 2016. The U.S. federal research and development tax credit received a permanent extension in December of 2015. In first quarter 2016, we reversed a portion of our tax reserve upon completion of the Joint Committee on Taxation's review of the U.S. tax audit for the tax years 2010 through 2012. Additionally. our first quarter 2015 effective tax rate included a higher level of certain deductions that were not allowed for tax purposes, contributing to the higher effective tax rate as compared to first quarter 2016.

PART II — OTHER INFORMATION

Item 1.LEGAL PROCEEDINGS.

Huawei Arbitration

Reference is made to the Huawei Arbitration previously disclosed in the 2015 Form 10-K. On March 28, 2016, the United States District Court for the Southern District of New York (the “New York District Court”) issued an order setting the amount of the security Huawei was required to post in connection with the stay of the New York Proceeding pending Huawei’s action in the Paris Court of Appeal requesting annulment of the arbitration award (the “Paris Proceeding”). A hearing in the Paris Proceeding was held on March 8, 2016, and on April 12, 2016, the Paris Court of Appeal denied Huawei's request to annul the arbitration award. Huawei has indicated that it is considering an appeal of the Paris Court of Appeal decision to the highest court in France. On April 26, 2016, the parties submitted a proposed order to the New York District Court, which was entered by the court that same day, notifying the court of their agreements regarding payments under the partial and final arbitration awards and the status of the New York Proceeding. As it considers whether to pursue an appeal of the Paris Court of Appeal decision, Huawei has agreed to make payments, without prejudice to its right to a further appeal, of amounts currently outstanding and amounts that become due under the arbitration awards (including the resulting license agreement). In addition, InterDigital has agreed not to seek to lift the stay in the New York Proceeding pending receipt of all such payments and pending any further appeal that Huawei has the right to pursue to the courts of France, and not to require Huawei to post security. We expect the first payment under the arbitration awards and license agreement to be made in second quarter 2016. We will recognize the related revenue in the period in which all criteria for revenue recognition have been met.

LG Arbitration

Reference is made to the arbitration initiated against InterDigital by LG Electronics, Inc. in March 2012 previously disclosed in the 2015 Form 10-K. On February 29, 2016, the New York District Court entered judgment on InterDigital’s February 2016 petition to confirm the December 2015 arbitration award.

Microsoft Sherman Act Delaware Proceedings

Reference is made to the proceedings initiated against InterDigital by Microsoft Mobile, Inc. and Microsoft Mobile Oy (collectively, “Microsoft”) in the United States District Court for the District of Delaware (the “Delaware District Court”) in August 2015 previously disclosed in the 2015 Form 10-K. A hearing on InterDigital's motion to dismiss and strike Microsoft's complaint was held on March 1, 2016, and on April 13, 2016, the Delaware District Court denied InterDigital's motion. On April 27, 2016, InterDigital filed a motion with the Delaware District Court to certify questions addressed in the court’s April 13, 2016 decision for interlocutory appeal.

Sharp Arbitration

On December 19, 2014, Sharp Corporation (“Sharp”) filed a demand for arbitration against the Company’s wholly owned subsidiary InterDigital Technology Corporation (“ITC”) with the American Arbitration Association’s International Center for Dispute Resolution.  Sharp’s demand for arbitration is based on ITC’s alleged breach of the August 10, 2001 patent license agreement (as amended) (the “2001 PLA”) between Sharp and ITC.  Sharp claims that ITC breached its FRAND commitments under the ETSI IPR policy, Section 6.1, by enforcing the 2001 PLA, thereby requiring Sharp to pay what it alleges to be excessive and discriminatory royalties.  Sharp also claims that ITC breached the implied covenant of good faith and fair dealing in the 2001 PLA by charging what Sharp alleges are excessive and discriminatory royalties. Sharp further alleges that ITC should be promissorily estopped from charging allegedly excessive and discriminatory royalties, and that ITC should provide an accounting of overpayments resulting from ITC’s alleged failure to observe its FRAND commitments.  Sharp is seeking (a) a declaration that ITC breached its FRAND commitments and breached the implied covenant of good faith and fair dealing, (b) calculation of new FRAND rates for the 2001 PLA, and (c) an order that ITC must return an amount to be determined for Sharp’s alleged overpayment under the 2001 PLA. Based on recent submissions by Sharp, we have reason to believe that Sharp may seek to amend its claims to allege that ITC breached a contractual provision that was included in the original 2001 PLA, prior to subsequent amendment. In addition, based on recent submissions by Sharp, we have reason to believe that Sharp may seek as damages a refund of a substantial majority of the royalties paid by Sharp under the 2001 PLA plus interest, resulting in an aggregate amount of damages of up to approximately $390 million. The arbitration is scheduled for an evidentiary hearing in July 2016.

34

The Company has not recorded any accrual at March 31, 2016 for contingent losses associated with this matter based on its belief that losses, while reasonably possible, are not probable in accordance with accounting guidance. Further, the possible range of loss, if any, cannot be reasonably estimated at this time.

Nokia and ZTE 2013 USITC Proceeding (337-TA-868) and Related Delaware District Court Proceedings

Reference is made to the USITC proceeding and related Delaware District Court proceedings initiated in January 2013 involving InterDigital, Nokia and ZTE previously disclosed in the 2015 Form 10-K. On March 18, 2016, the Delaware District Court denied ZTE’s motion for judgment as a matter of law, or in the alternative for a new trial, with respect to the ’966 and ’847 patents. The court postponed its ruling on ZTE’s motion as to the ’244 patent pending the U.S. Court of Appeals for the Federal Circuit’s decision on InterDigital’s appeal of the September 14, 2015 PTAB ruling and administratively closed that portion of the motion. On April 8, 2016, the court set a new schedule for the FRAND/damages portion of the ZTE case with a target trial date in February 2018.

On April 18, 2016, ZTE filed a stipulated request for dismissal with prejudice of its counterclaims for breach of contract and patent unenforceability based on FRAND and withdrew its corresponding FRAND-related affirmative defenses. Also on April 18, 2016, ZTE filed a motion under Federal Rule of Civil Procedure 54(b) seeking certification of partial final judgment on the claims for infringement of the ’966 and ’847 patents to allow ZTE to file an immediate appeal as to those patents. The motion is pending.

Nokia and ZTE 2011 USITC Proceeding (337-TA-800) and Related Delaware District Court Proceeding

Reference is made to the USITC proceeding and related Delaware District Court proceeding initiated in July 2011 involving InterDigital, Nokia and ZTE previously disclosed in the 2015 Form 10-K. The Delaware District Court proceeding is currently stayed through June 15, 2016.

See Note 5, “Litigation and Legal Proceedings,” to the Notes to Condensed Consolidated Financial Statements included in Part I, Item 1 of this Quarterly Report on Form 10-Q for further discussion regarding these and other proceedings.

Item 1A.RISK FACTORS.

In addition to the factors set forth in the Statement Pursuant to the Private Securities Litigation Reform Act of 1995 -- Forward-Looking Statements in Part I, Item 2 of this Quarterly Report on Form 10-Q, you should carefully consider the factors discussed in Part I, Item 1A Risk Factors of the 2015 Form 10-K, which could materially affect our business, financial condition or future results. The risks described in this Quarterly Report on Form 10-Q and in the 2015 Form 10-K are not the only risks facing our company. Additional risks and uncertainties not currently known to us or that we currently deem to be immaterial also may materially and adversely affect our business, financial condition and/or operating results.
