Report of independent public accountants To the Plan Administrator of the InterDigital Communications Corporation Savings and Protection Plan We were engaged to audit the accompanying financial statements and supplemental schedule of the InterDigital Communications Corporation Savings and Protection Plan (the Plan) as of December 31, 2000 and 1999, and for the year ended December 31, 2000 as listed in the accompanying index. These financial statements and the schedule referred to below are the responsibility of the Plan's management. As permitted by 29 CFR 2520.103-8 of the Department of Labor's Rules and Regulations for Reporting and Disclosure under the Employee Retirement Income Security Act of 1974 the plan administrator instructed us not to perform, and we did not perform, any auditing procedures with respect to the information summarized in Note 1, which was certified by The Principal Life Insurance Company, the custodian of the Plan for 2000 and 1999, except for comparing such information with the related information included in the 2000 and 1999 financial statements and supplemental schedule. We have been informed by the plan administrator that the custodian holds the Plan's investment assets and executes investment transactions. The plan administrator has obtained a certification from the custodian as of December 31, 2000 and 1999 and for the year ended December 31, 2000, that the information provided to the plan administrator by the custodian is complete and accurate. Because of the significance of the information that we did not audit, we are unable to, and do not, express an opinion on the accompanying financial statements and schedule taken as a whole. The form and content of the information included in the financial statements and schedule, other than that derived from the information certified by the custodian, have been audited by us in accordance with auditing standards generally accepted in the United States and, in our opinion, are presented in compliance with the Department of Labor's Rules and Regulations for Reporting and Disclosure under the Employee Retirement Income Security Act of 1974 /s/ Arthur Andersen LLP Philadelphia, Pennsylvania September 10, 2001 1 Report of Independent Accountants To the Participants and Administrator of InterDigital Communications Corporation Savings and Protection Plan: In our opinion, the accompanying statements of net assets available for benefits and the related statements of changes in net assets available for benefits present fairly, in all material respects, the net assets available for benefits of InterDigital Communications Corporation Savings and Protection Plan (the "Plan") at December 31, 2001 and for the year then ended, as listed in the accompanying index, in conformity with accounting principles generally accepted in the United States of America. 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 audit. We conducted our audit of these statements in accordance with auditing standards generally accepted in the United States of America, which 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, assessing the accounting principles used and significant estimates made by management, and evaluating the overall financial statement presentation. We believe that our audit provides a reasonable basis for our opinion. Our audit was conducted for the purpose of forming an opinion on the basic financial statements taken as a whole. This supplemental schedule of assets (held at end of year) is presented for the purpose of additional analysis and is not a required part of the basic financial statements but is supplementary 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 schedule is the responsibility of the Plan's management. The supplemental schedule has been subjected to the auditing procedures applied in the audit of the basic financial statements and, in our opinion, is fairly stated in all material respects in relation to the basic financial statements taken as a whole. As permitted by 29 CFR 2520.103-8 of the Department of Labor's Rules and Regulations for Reporting and Disclosure under the Employee Retirement Income Security Act of 1974, the plan administrator instructed us not to perform, and we did not perform, any auditing procedures with respect to the information summarized in Note 6, which was certified by The Principal Life Insurance Company, the trustee of the Plan, except for comparing such information with the related information included in the financial statements. We have been informed by the plan administrator that the trustee holds the Plan's investment assets and executes investment transactions. The plan administrator has obtained a certification from the trustee as of December 31, 2001 and for the year then ended, that the information provided to the plan administrator by the trustee is complete and accurate.

Participants should refer to the Plan document for a more complete description of the Plan's provisions. General The Plan is a voluntary, defined contribution 401(k) plan for salaried and hourly employees of InterDigital Communications Corporation and its participating subsidiaries (the "Company") over the age of 18 who have completed one month of service. The Plan was established effective February 1, 1985 and restated effective January 1, 1997. The Plan is subject to the provisions of the Employee Retirement Income Security Act of 1974 ("ERISA"). Contributions All participant contributions are made on a before-tax basis. Each participant may contribute from 1% to 15% of his or her annual compensation. Participant contributions cannot exceed Internal Revenue Service ("IRS") limitations for each plan year. For the 2001 and 2000 plan years, the IRS limit was $10,500. If a participant's annual contributions exceed the dollar limitation set by the IRS, 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 to reduce future employer contributions. The Company may, at its sole discretion, contribute to the Plan through matching contributions and/or discretionary contributions. Beginning July 2001, the Company matches 50% of each participant's contribution, up to a maximum of 6% of a participant's pretax annual compensation. 50% of the Company match consists of cash and the other 50% is paid in the form of the Company's common stock. Discretionary contributions are lump-sum payments made to the Plan as determined from time to time by the Board of Directors of the Company. The Company did not make any discretionary contributions in 2001 or 2000. The law limits the amount of annual compensation that may be used to determine contributions. The limit was $170,000 in 2001 and 2000. The law also limits the amount of all contributions that can be made for or by a participant to the Plan in a year. That limit for 2001 was the lesser of 25% of annual compensation or $35,000. In 2000 the limit was the lesser of 25% of annual compensation or $30,000. Employee rollover contributions from other qualified retirement plans are permitted; such rollover contributions are subject to the conditions and procedures set forth in the Plan. Participant Accounts Each participant's account is credited with that participant's contributions and allocations of the Company's matching and discretionary contributions and Plan earnings and losses. Allocations of discretionary contributions are based on a participant's annual compensation relative to the total compensation of all other participants. The benefit to which a participant is entitled is the benefit that can be provided from the participant's vested account. Terminating participants forfeit nonvested Company contributions. Forfeitures are used to pay Plan expenses or reduce employer contributions. Vesting Participants are immediately vested in their salary deferral and rollover contributions. Vesting in Company contributions is based on length of service. Participants vest 33% immediately upon commencement of employment. At their first and second anniversary of employment, individual participants are 67% and 100% vested, respectively. 5 Participant Loans Any participant who is an active employee may apply for a secured loan provided the request does not exceed the lesser of 50% of the vested account balance or $50,000. The minimum loan amount is $1,000. Only one loan may be made every 365 days and all loans are subject to approval by the Plan administrator. Loan terms are limited to five years. Upon termination of employment the outstanding principal and accrued interest balance is immediately payable. Interest rates are determined by the Plan administrator in accordance with prevailing market rates on similar types of loans, ranging between 6.50% and 11.00% at December 31, 2001. 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 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. When a participant receives a distribution from the Plan, any outstanding principal plus accrued interest will be deducted from the amount of the distribution. Payment of Benefits If a participant retires, dies, becomes permanently disabled, or otherwise separates from the Company, the participant or participant's beneficiary is entitled to the vested amount of his account as valued on the applicable valuation date. In the event of a participant's death, distribution of the participant's account will be made as soon as administratively practicable upon the receipt of appropriate documentation from the participant's designated beneficiary. Distributions for reasons of retirement, permanent disability or termination will be made upon written request. Distributions of a participant's account are typically made, subject to certain limitations, in a single payment, installment or deferred payment for the vested value of his/her account. 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 participants' accounts shall become fully vested and all accounts of participants shall be distributed as soon as administratively possible. 6 Investment Options All investments are participant directed except for 50% of the match contribution which by the terms of the Plan, is invested in Company stock. During the Plan years ending December 31, 2001 and 2000, participants were able to allocate their contributions, in 1% increments, among the following investment options: Guaranteed Interest Account This account invests in private-market bonds, commercial mortgages and mortgage backed securities.

Plan Amendments In June 2001, the Company's Compensation and Stock Option Committee authorized an amendment to the Plan to include increasing the Company's matching contribution from 25% to 50% of the first 6% of a participant's annual compensation that a participant contributes to the Plan (paying the 25% increased matching contribution in the Company's stock), adding the Company's stock to the selection of investment funds under the Plan, permitting an additional discretionary year-end Company contribution and, effective January 1, 2002, extending the vesting period for Company contributions to 36 months from the commencement of employment. The prior vesting policy permitted immediate vesting of 33% upon commencement of employment and vesting of 67% and 100% on the first and second anniversaries of commencement of employment, respectively. In August 2001, 400,000 shares of the Company's authorized but unissued common stock were reserved for issuance to the account of participants in the Plan as matching contributions. An agreement was entered into between the Company on behalf of the Plan and Web401(k).com and Fidelity Investments to serve as third party administrator and Custodian, respectively, of the InterDigital Stock Fund. Reclassifications Certain reclassifications have been made to prior year financial statements to conform to the current year presentations. NOTE 2 - SUMMARY OF ACCOUNTING POLICIES The following accounting policies, which conform with accounting principles generally accepted in the United States of America, have been used consistently in the preparation of the Plan's financial statements: 9 Basis of Accounting 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 accounting principles generally accepted in the United States of America, requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure 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 Guaranteed Investment Contracts are stated at fair value. Shares of registered investment companies are valued at quoted market prices which represent the net asset value of shares held by the Plan at year-end. The InterDigital Stock Fund is valued at its year end unit closing price (comprised of common stock market price plus uninvested cash position). Participant loans are valued at cost, which approximates fair value. 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. Payment of Benefits Benefits are recorded when paid. Forfeited Accounts At December 31, 2001 forfeited nonvested accounts totaled $7,974. These forfeited accounts were fully utilized to reduce employer contributions with respect to 2001. NOTE 3 - INVESTMENT CONTRACT WITH INSURANCE COMPANIES The Guaranteed Interest Account (the "Account") provides a guaranteed interest rate for a two year and five year period. The rate credited to the Account is the rate in effect on the day when each deposit is directed to the Account. To simplify reporting to Plan participants, all rates credited during the twelve-month period are averaged into a single composite rate. The guarantees made with regard to the Account are supported by the general account of the Principal Financial Group. The general account is invested mostly in private placement bonds, commercial mortgages, and residential mortgages. The Account promises contract value for a benefit event, however, there is a market adjustment when funds are withdrawn prior to their maturity. Thus, the Account is not considered benefit responsive. 10 NOTE 4 - INVESTMENTS During 2001 and 2000, the Plan's investments (including gains and losses on investments bought and sold, as well as held during the year) appreciated (depreciated) in value as follows: December 31, 2001 2000 ------------------ ------------------ Pooled Separate Accounts $ (488,229) $ (126,136) Registered Investment Companies (115,673) - Company Stock 24,797 - ------------------ ------------------ $ (579,105) $ (126,136) ================== ================== NOTE 5 - NONPARTICIPANT-DIRECTED INVESTMENTS Information about the components of and significant changes in net assets relative to the Plan's nonparticipant-directed investments are as follows: December 31, 2001 2000 ------------------ ------------------ Net Assets: InterDigital Stock Fund $ 155,477 $ - ========= ======== Year Ended December 31, 2001 2000 ------------------ ------------------ Changes in Net Assets: Contributions $ 132,048 $ - Dividend Income 68 - Net Appreciation in Fair Value of - Investments 24,742 Administrative Expenses (1,381) - NOTE 6 - RELATED PARTY TRANSACTIONS The Plan invests in shares of the Company's stock through the InterDigital Stock Fund and in Pooled Separate Account and Guaranteed Interest Account investments with the Principal Financial Group. Transactions in such investments qualify as party-in-interest transactions that are exempt from the prohibited transaction rules. 11 NOTE 7- PLAN EXPENSES All costs and expenses, exclusive of fees for participant loans, incurred in the administration of the Plan (i.e., trustee and recordkeeper fees) are currently paid by the Company. NOTE 8 -TAX STATUS The IRS has determined and informed the Company by letter dated March 8, 2002 that the Plan satisfies the qualification requirements under Internal Revenue Code ("IRC") Section 401(a) and that the trust maintained in connection with the Plan satisfies the requirements for exemption under Section 501(a) of the IRC. The Company believes the Plan is designed and is currently being operated in compliance with the applicable requirements of the IRC. NOTE 9 -DEMUTUALIZATION PROCESS On March 31, 2001, the board of directors of Principal Mutual Holding Company unanimously adopted a plan converting the mutual organization into a stock company, a form of conversion known as demutualization. The demutualization was governed by Iowa law, which required approval by policyholders entitled to vote on the plan of conversion by two-thirds of the votes cast, and also by the Insurance Commissioner of the State of Iowa. The policyholders entitled to a vote on the plan of conversion approved the plan at a meeting on July 24, 2001, by approximately 92% of the votes cast. A public hearing was held on the plan of conversion on July 25, 2001, and the Insurance Commissioner of the State of Iowa approved the plan of conversion on August 28, 2001. Under the terms of the plan of conversion, effective October 26, 2001, Principal Financial Group completed its initial public offering. All membership interests in Principal Mutual Holding Company were extinguished on that date and eligible policyholders received compensation in the form of shares credited to the Principal Financial Group Income Separate Account. In December 2001, distribution to the Plan of demutualization compensation occurred in the amount of $209,198. 12 Schedule 1 INTERDIGITAL COMMUNICATIONS CORPORATION SAVINGS AND PROTECTION PLAN Schedule of Assets (Held at End of Year) As of December 31, 2001 -------------------------------------------------------------------------------- InterDigital Communications Corporation Savings and Protection Plan - InterDigital Communications Corporation EIN 23-1882087 Attachment to Form 5500, Schedule H, Part IV, Line i: Identity of Issue Investment Type Current Value -------------------------------------------------------------------------------------------------------------------- Guaranteed interest account Pooled Separate Accounts $ 382,996 Money market separate account Pooled Separate Accounts 799,669 Bond & mortgage separate account Pooled Separate Accounts 571,835 Government securities separate account Pooled Separate Accounts 281,626 Bond emphasis balanced separate account Pooled Separate Accounts 363,675 Large cap stock index separate account Pooled Separate Accounts 2,620,540 Large company blend separate account Pooled Separate Accounts 851,298 Medium company value separate account Pooled Separate Accounts 557,176 Real estate separate account Pooled Separate Accounts 171,999 Stock emphasis balanced separate account Pooled Separate Accounts 267,851 Medium company blend separate account Pooled Separate Accounts 826,993 Small company blend separate account Pooled Separate Accounts 904,703 International stock separate account Pooled Separate Accounts 341,401 Principal Financial Group income stock separate account Pooled Separate Accounts 267,957 Strong Opportunity Fund Registered Investment Company 196,450 Vanguard Growth & Income Fund Registered Investment Company 65,228 INVESCO Small Company Growth Fund Registered Investment Company 73,550 Janus Aspen Aggregate Growth Fund Registered Investment Company 122,150 T.
