REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM


To the Participants and Plan Administrator of
InterDigital Savings and Protection Plan
Wilmington, Delaware


We have audited the accompanying statements of net assets available for benefits of the InterDigital Savings and Protection Plan as of December 31, 2015 and 2014, and the related statements of changes in net assets available for benefits for the years then ended. These financial statements are the responsibility of the Plan's management. Our responsibility is to express an opinion on these financial statements based on our audits.

We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the financial statements referred to above present fairly, in all material respects, the net assets available for benefits of the Plan as of December 31, 2015 and 2014, and the changes in net assets available for benefits for the years then ended, in conformity with accounting principles generally accepted in the United States of America.

The supplemental information in the accompanying schedule of assets held at end of year as of December 31, 2015 and schedule of delinquent participant contributions for the year ended December 31, 2015 has been subjected to audit procedures performed in conjunction with the audit of the InterDigital Savings and Protection Plan's financial statements. The supplemental information is presented for the purpose of additional analysis and is not a required part of the financial statements but include supplemental information required by the Department of Labor's Rules and Regulations for Reporting and Disclosure under the Employee Retirement Income Security Act of 1974. This supplemental information is the responsibility of the Plan's management. Our audit procedures included determining whether the supplemental information reconciles to the financial statements or the underlying accounting and other records, as applicable, and performing procedures to test the completeness and accuracy of the information presented in the supplemental information. In forming our opinion on the supplemental information in the accompanying schedules, we evaluated whether the supplemental information, including its form and content, is presented in conformity with the Department of Labor's Rules and Regulations for Reporting and Disclosure under the Employee Retirement Income Security Act of 1974. In our opinion, the supplemental information in the accompanying schedules is fairly stated in all material respects in relation to the financial statements as a whole.

INTERDIGITAL
SAVINGS AND PROTECTION PLAN
NOTES TO FINANCIAL STATEMENTS

NOTE 1 - DESCRIPTION OF THE PLAN
The following description of the InterDigital Savings and Protection Plan (the “Plan”) is provided for general information purposes. Plan participants should refer to the Plan agreement for a more complete description of the Plan's provisions.
General
The Plan is a defined contribution 401(k) plan of InterDigital, Inc. and its participating subsidiaries (the “Company” or “InterDigital”) for its eligible employees. An eligible employee will be eligible to participate in the Plan in the next payroll period, or as soon as administratively possible, following the date the eligible employee attained age 18 and completed one month of service with the Company.
The following individuals are not eligible to participate in the Plan: (i) individuals employed by the Company as part of an academic course of study, such as a work-study program, co-op program or similar arrangements; (ii) collective bargaining employees; (iii) leased employees within the meaning of Internal Revenue Code (“IRC”) Sections 414(n)(2) and 414(o)(2); and (iv) nonresident aliens who receive no earned income that constituted income from sources within the United States.
The Plan was established effective February 1, 1985, restated January 1, 1997, restated January 1, 2007, when the Plan name was changed from InterDigital Communications Corporation Savings and Protection Plan to InterDigital Savings and Protection Plan, and most recently amended and restated effective January 1, 2010. The Plan is subject to the provisions of the Employee Retirement Income Security Act of 1974, as amended (“ERISA”). State Street Bank & Trust Company is the trustee of the Plan. Transamerica Retirement Solutions, LLC ("Transamerica"), formerly known as Diversified Investment Advisors, is the Plan custodian and third party administrator of the Plan's assets.
Contributions
Participant contributions are made on a pre-tax basis and/or an after-tax basis. Each participant may invest from 1% to 100% of eligible compensation as a basic contribution subject to state, local, and certain Federal taxes. The total of the basic and supplemental contributions cannot exceed IRC limitations for each Plan year. For the 2015 and 2014 Plan years, such limit was $18,000 and $17,500, respectively. Participants who have attained the age of 50 before the end of the Plan year are eligible to make catch-up contributions. In 2015 and 2014, the maximum additional annual contribution was $6,000 and $5,500, respectively. If a participant's annual contributions exceed the dollar limitation set by the IRC, thereby requiring a distribution of such excess contributions, the participant will forfeit any employer matching contributions related to the distribution amount. Amounts forfeited will be used by the Company to reduce future employer matching contributions.
The Company may, at its sole discretion, contribute to the Plan through matching contributions and/or discretionary employer contributions. The Company currently matches 50% of the first 6% of each participant's eligible earnings contributed to the Plan. There were no discretionary employer contributions made for the years ended December 31, 2015 and December 31, 2014. Effective January 1, 2013, the Plan was amended to allow discretionary employer matching contributions to be made by the Company in an amount not to exceed 6% of a participant's annual compensation, thereby allowing for true-ups to be made to ensure participants receive the maximum matching contributions irrespective of deduction timing.
The IRC limits the amount of pay that may be used to determine participants' discretionary contributions. The limit was $265,000 and $260,000 in 2015 and 2014, respectively. The IRC also limits the amount of all contributions that can be made for or by a participant to the Plan in a given year. The limit was the lesser of 100% of pay or $53,000 or $52,000 for 2015 and 2014, respectively.
Employee rollover contributions from other qualified retirement plans are permitted; such contributions are subject to the conditions and procedures set forth in the Plan.

4



Participant Accounts
Each participant's account is credited with that participant's contributions, allocations of the Company's matching contributions, discretionary employer contributions, if any, and Plan earnings and losses. Allocations of discretionary employer contributions are based on a percentage of a participant's eligible compensation as determined by the Board of Directors of the Company. The benefit to which a participant is entitled is the benefit that can be provided from the participant's vested account. Terminated participants forfeit unvested Company contributions. Forfeitures are used to reduce future employer matching contributions.
Vesting
Rollover contributions and participants' before and after-tax contributions are 100% vested and nonforfeitable. Plan participants who were credited with an Hour of Service (as defined in the Plan) shall be vested in their discretionary matching and employer contributions as follows:
Periods of Service
 
Percentage
Less than 1 year
 
%
At least 1, less than 2 years
 
33
%
At least 2, less than 3 years
 
67
%
3 or more years
 
100
%
Participants who die while an employee of InterDigital or retire at their normal retirement age (age 65) are 100% vested in their account, regardless of their length of service.
Notes Receivable from Participants
Any participant who is an active employee may apply for a secured loan provided the request does not exceed the lesser of 50% of their vested account balance or $50,000. The minimum loan amount is $500. Only one loan per participant may be made every 365 days and all loans are subject to approval by the Company as Plan Administrator. Loan terms are limited to five years set at the inception of each loan. Interest rates are set at an annual rate of prime + 1%. The rate on all outstanding loans at December 31, 2015 and 2014 was between 4.25% and 4.5%. Interest paid by the participant is credited to the participant's account. If a participant's balance remains unpaid for more than 90 days after it is due, the loan will be in default on the outstanding loan amount and the participant's vested account will be reduced by the amount of the unpaid principal and interest. The unpaid amount is treated as a taxable withdrawal and is subject to federal income taxes. Loans in default, in principal plus interest that were reclassified to distributions, amounted to $9,761 and $23,875 for the years ended December 31, 2015 and 2014, respectively. Participants may continue to make scheduled loan payments after the related participant ceases to be an employee or party-in-interest as defined by ERISA.
When a participant receives a distribution from the Plan, any outstanding principal plus accrued interest will be deducted from the amount of the distribution. A participant may then either default on the loan or make arrangements to continue loan repayments beyond when they become entitled to a distribution as long as their remaining interest in the Plan exceeds their outstanding loan balance.
Payment of Benefits
If a participant retires, dies, becomes permanently disabled, or otherwise separates from the Company, the participant or participant's beneficiary, as applicable, is entitled to the vested amount of their account as valued on the applicable valuation date. In the event of a participant's death, distribution of their account will be made as soon as administratively practicable upon the receipt of appropriate documentation from their designated beneficiary. Distributions for reasons of retirement, permanent disability or termination will be made upon written request. Distributions from a participant's account are made in a single lump sum payment. Employees may defer payment of their account under the Plan.
Plan Termination
The Company may amend or suspend the Plan and may terminate the Plan at any time subject to the provisions of ERISA; although there is no present intent to do so. However, no such action may cause the Plan's assets to be used for purposes other than the exclusive benefit of the participants and their beneficiaries. If the Plan is terminated, all such participants' accounts shall become fully vested and all accounts of participants shall be distributed as soon as administratively possible.

NOTE 2 - SUMMARY OF ACCOUNTING POLICIES
The following accounting policies, which conform with accounting principles generally accepted in the United States(“GAAP”), have been used consistently in the preparation of the Plan's financial statements.
Basis of Accounting

7



Accounting records are maintained by the custodian on the cash basis of accounting. The financial statements of the Plan reflect all material adjustments to place the financial statements on the accrual basis of accounting.
Use of Estimates
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 at the date of the financial statements, as well as reported amounts of additions and deductions during the reporting period. Actual results could differ from those estimates.
Investment Valuation and Income Recognition
Investments are reported at fair value. Fair value is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. See Note 3 for discussion of fair value measurements.
Purchases and sales of investments are recorded on a trade-date basis. Interest income is accrued when earned. Dividend income is recorded on the ex-dividend date. Capital gain distributions are included in dividend income.
Notes Receivable from Participants
Notes receivable from participants are measured at their unpaid principal balance plus any accrued but unpaid interest. Interest income is recorded on the accrual basis. Related fees are recorded as administrative expenses and are expensed when they are incurred. No allowance for credit losses has been recorded as of December 31, 2015 or December 31, 2014. If a participant ceases to make loan repayments and the plan administrator deems the participant loan to be in default, the participant loan balance is reduced and a benefit payment is recorded.
Payment of Benefits
Benefits are recorded when paid.
Forfeited Accounts
At December 31, 2015 and 2014, forfeited non-vested accounts totaled $34,260 and $30,537, respectively. No amounts were used to reduce employer matching contributions in either year.
Recently Adopted Accounting Pronouncements
In May 2015, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update 2015-07, Fair Value Measurement (Topic 820), Disclosures for Investments in Certain Entities that Calculate Net Asset Value per Share (or Its Equivalent) ("ASU 2015-07"). The amendments in ASU 2015-07 relate to fair value measurement and the disclosures for investments in certain entities that calculate net asset value ("NAV") per share (or its equivalent). The updated guidance applies to reporting entities that elect to measure the fair value of certain investments using the NAV per share (or its equivalent) of the investment as a practical expedient. Currently, investments valued using the practical expedient are categorized within the fair value hierarchy on the basis of when the investment is redeemable with the investee at NAV. The amendments remove the requirement to categorize within the fair value hierarchy all investments for which fair value is measured using the NAV per share practical expedient. The amendments also remove the requirement to make certain disclosures for all investments that are eligible to be measured at fair value using the NAV per share practical expedient. Rather, those disclosures are limited to investments for which the entity has elected to measure the fair value using that practical expedient. The amendments are effective for the Plan for fiscal years beginning after December 15, 2015 and shall apply retrospectively to all periods presented. Earlier application is permitted and the Plan's administrator has elected to early adopt ASU 2015-07. Other than the changes to classification and disclosure, the adoption of this ASU did not have a material impact on the Plan's financial statements.

8



In July 2015, the FASB issued ASU 2015-12, Plan Accounting: Defined Benefit Pension Plans (Topic 960), Defined Contribution Pension Plans (Topic 962), Health and Welfare Benefit Plans (Topic 965): (Part I) Fully Benefit-Responsive Investment Contracts, (Part II) Plan Investment Disclosures, (Part III) Measurement Date Practical Expedient ("ASU 2015-12"). Part I eliminates the requirements to measure fully benefit-responsive investment contracts at fair value, including common collective trust assets, and provide certain disclosures. Contract value is the only required measure for fully benefit-responsive investments. Part II eliminates the requirements to disclose individual investments that represent five percent or more of net assets available for benefits and the net appreciation or depreciation in fair value of investments by general type. Part II also simplifies the level of disaggregation of investments that are measured using fair value. Plans will continue to disaggregate investments that are measured using fair value by general type; however, plans are no longer required to also disaggregate investments by nature, characteristics or risks. Further, the disclosure of information about fair value measurements shall be provided by general type of plan asset. Part III is not applicable to the Plan. ASU 2015-12 is effective for fiscal years beginning after December 15, 2015, with early adoption permitted. Parts I and II are to be applied retrospectively. The Plan administrator has elected to early adopt Part I of ASU 2015-12. As a result of the adoption, the Statements of Net Assets Available for Benefits have been retrospectively adjusted to report collective trusts at the NAV practical expedient and the adjustment from fair value to contract value for interests in a collective trust relating to a fully benefit-responsive investment contract has been removed. Additionally, the Notes to the Financial Statements have been retrospectively adjusted to reflect the simplified disclosures permitted by ASU 2015-12.
Recently Issued Accounting Pronouncements Not Yet Adopted
As of December 31, 2015, there were no recently issued accounting standards not yet adopted which are expected to have a material effect on the Plan's financial statements.
NOTE 3 - FAIR VALUE MEASUREMENTS
The framework for measuring fair value provides a fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1) and the lowest priority to unobservable inputs (Level 3). The three levels of the fair value hierarchy under FASB ASC 820 are described as follows:
Level 1
Inputs to the valuation methodology are unadjusted quoted prices for identical assets or liabilities in active markets that the Plan has the ability to access;
Level 2
Inputs to the valuation methodology include:
     -Quoted prices for similar assets or liabilities in active markets;
     -Quoted prices for identical or similar assets or liabilities in inactive markets;
     -Inputs other than quoted prices that are observable for the asset or liability; and
     -Inputs that are derived principally from or corroborated by observable market data by correlation or other means.
If the asset or liability has a specified (contractual) term, the Level 2 input must be observable for substantially the full term of the asset or liability.
Level 3
Inputs to the valuation methodology are unobservable and significant to the fair value measurement.
The asset's or liability's fair value measurement level within the fair value hierarchy is based on the lowest level of any input that is significant to the fair value measurement. Valuation techniques used need to maximize the use of observable inputs and minimize the use of unobservable inputs.
Following is a description of the valuation methodologies used for assets measured at fair value. There have been no changes in the methodologies used at December 31, 2015 and 2014.
InterDigital stock : Valued at its year-end unit closing price (comprised of common stock market price plus uninvested cash position).

9



Registered investment companies : Valued at the quoted market prices on the active market representing the net asset value (“NAV”) of shares held by the Plan at year-end.
Stable Pooled Fund : A stable value fund that is a fund composed primarily of fully benefit-responsive investment contracts that is valued at the NAV of units of the bank collective trust. The NAV is used as a practical expedient to estimate fair value. This practical expedient would not be used if it is determined to be probable that the fund will sell the investment for an amount different from the reported NAV. Participant transactions (purchases and sales) may occur daily. If the Plan initiates a full redemption of the collective trust, the issuer reserves the right to require 30 days notification in order to ensure that securities liquidations will be carried out in an orderly business manner.
The following tables set forth by level, within the fair value hierarchy, the Plan's assets at fair value as of December 31, 2015 and December 31, 2014:

The Plan invests in various investment securities. Investment securities are exposed to various risks such as interest rate, market, and credit risks. Due to the level of risk associated with certain investment securities, it is at least reasonably possible that changes in the values of investment securities will occur in the near term and that such changes could materially affect participants' account balances and the amounts reported in the Statement of Net Assets Available for Benefits.

NOTE 5 - RELATED PARTY TRANSACTIONS
The Plan invests in shares of the Company's common stock through the InterDigital Stock Fund. For the first half of 2014, the Plan also invested in funds managed by Transamerica. Transactions in such investments qualify as party-in-interest transactions that are exempt from the prohibited transaction rules.

NOTE 6 - PLAN EXPENSES
Effective March 1, 2014, an amendment to the Pension Services Agreement between Transamerica and the Company was made to revise the way costs and expenses incurred in the administration of the Plan are paid and allocated among participants. Pursuant to Transamerica’s Fund Revenue Equalization method, Transamerica uses certain revenue sharing payments it receives from the Investment Options available in the Plan to offset the costs of

11



administration of the Plan on an individual fund basis. If the revenue Transamerica collects from a fund provider is greater than the administrative fee negotiated, Transamerica refunds the difference to the participants invested in the fund. If the revenue Transamerica collects from a fund provider is less than the negotiated fee, it collects the difference by deducting an administrative fee from the participants invested in the fund. Transamerica’s Fund Revenue Equalization method ensures that all participants bear a similar percentage charge for the Plan's administrative fees irrespective of the investment funds they choose. Additional amounts in excess of its required revenue are credited to the "Expense Budget Account." If the amount received by Transamerica is less than its required revenue and the funds in the Expense Budget Account are insufficient to cover the shortfall, the Company pays the shortfall.
The amount of the credit to the Expense Budget Account in 2015 and 2014 was $99,777 and $97,615, respectively.
NOTE 7 - TAX STATUS
The Internal Revenue Service (“IRS”) has determined and informed the Company by letter dated July 5, 2012 that the Plan satisfies the qualification requirements under IRC Section 401(a) and that the trust maintained in connection with the Plan satisfies the requirements for exemption under IRC Section 501(a). The Company believes the Plan is designed and is currently being operated in compliance with the applicable requirements of the IRC.
GAAP requires Plan management to evaluate tax positions taken by the Plan and recognize a tax liability (or asset) if the Plan had taken an uncertain position that more likely than not would not be sustained upon examination by the IRS. The Plan administrator has analyzed the tax positions taken by the Plan, and has concluded that, as of December 31, 2015, there are no uncertain positions taken or expected to be taken that would require recognition of a liability (or asset) or disclosure in the financial statements.
The Plan is subject to routine audits by taxing jurisdictions; however, there are currently no audits for any tax period in progress. The Plan Administrator believes it is no longer subject to income tax examinations for years prior to 2013.

NOTE 8 - NON EXEMPT PARTY-IN-INTEREST TRANSACTIONS


For the Plan years 2015, 2014 and 2013, the Company remitted certain participant contributions and loan repayments to Transamerica later than required under Department of Labor Regulation §2510.3-102. The Company has filed IRS Form 5330 to report and pay an excise tax with respect to the 2014 and 2013 late remittances and is in the process of filing IRS Form 5330 for 2015. During 2015, participant accounts were credited with the amount of investment income that would have been earned had the participant contributions been remitted on a timely basis for 2014 and 2013. Participant accounts will be credited with the amount of investment income that would have been earned had the participant contributions been remitted on a timely basis in 2015 upon final calculation by Transamerica. Such amounts are not material to the Plan’s financial statements.
