DESCRIPTION OF THE PLAN The following description of the Newport News Inc. 401(k) Investment Plan for Salaried Employees (the "Plan") provides only general information. Participants should refer to the plan document for a more complete description of the Plan's provisions. General - The Plan was adopted by Newport News Shipbuilding Inc. (the "Company" or "NNS"), effective December 16, 1996. As of November 7, 2001 the Company completed a merger agreement with Northrop Grumman Corporation ("Northrop Grumman") whereby the Company was subsequently merged with and into Northrop Grumman. The Plan is intended to constitute a defined contribution 401(k) plan that provides for tax-deferred savings and employer contributions to participants. The Company and Merrill Lynch Trust Co. (the "Trustee") have executed the Newport News Shipbuilding Inc. 401(k) Investment Plan for Salaried Employees Trust Agreement, which provides for the investment and reinvestment of the assets of the Plan. Through February 12, 2002, the Plan was administered by the Company's Benefits Committee (the "Committee"). The members of the Committee were appointed by the Company's Board of Directors (the "Board"). The Plan is subject to the applicable provisions of the Employee Retirement Income Security Act of 1974, as amended ("ERISA"). Eligibility and Contributions - All salaried employees are eligible to participate in the Plan as soon as administratively feasible. Approximately one week after receipt of their first paycheck, employees may contact the Trustee to enroll in the Plan. Participants may elect to voluntarily contribute a percentage of their annual before-tax compensation, not to exceed limitations imposed by the Internal Revenue Code ("IRC"), through equal pay period deductions. Participant contributions can range from 1 to 12 percent of annual compensation. Deferral contributions were capped at $10,500 for the years ended December 31, 2001 and 2000. The Company will provide a matching contribution equal to 50 percent of the first 8 percent of compensation deferred under the Plan, resulting in a cap of 4 percent for Company matched contributions. Company matching contributions were made in the form of the Company's stock through November 30, 2001 and in cash subsequent to that date. All of the Plan's participants, regardless of whether they make a contribution, also received a Company stock grant equal to 3 percent of the participant's base pay through November 30, 2001 and in cash subsequent to that date, each pay period through December 31, 2001. Participant Accounts - Each participant's account is credited with the participant's contribution, an allocation of the Plan's earnings or losses and Company matching contributions each pay period. Allocations are based on the participant's account balance, as defined in the plan document. - 5 - Vesting and Forfeitures - Participants are vested in Company matching contributions after completing two years of Company service. Forfeited contributions are applied to reduce future Company matching contributions. All participants are fully vested in the three percent stock grant and all other funds in their accounts. Payment of Benefits - Upon termination of employment, including layoff, distributions to participants are generally made via single lump-sum payments. Participants whose account balances exceed $5,000 have the right to defer the distribution of their account balances until they reach the age of 70 1/2. Investment Options - Upon enrollment in the Plan, participants may direct their contributions in one percent increments in any of the investment funds that are selected by the Committee. Loans to Participants - A participant may borrow up to 50 percent of his or her account balance with a minimum loan amount of $1,000. Loans are repayable through payroll deductions for a period no longer than five years. Interest on loans to participants is charged at a rate of prime (rate of interest charged by commercial banks on loans to preferred customers) plus one percent. The interest rates at December 31, 2001 and 2000 were 5.8 percent and 10.5 percent, respectively. 2. SIGNIFICANT ACCOUNTING POLICIES Basis of Accounting - The accompanying financial statements are prepared in accordance with accounting principles generally accepted in the United States of America. 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 net assets available for benefits and changes therein, and disclosure of contingent assets and liabilities. Actual results could differ from those estimates. Risk and Uncertainties - The Plan utilizes various investment instruments. Investment securities, in general, are exposed to various risks, such as interest rate, credit and overall market volatility. Due to the level of risk associated with certain investment securities, it is reasonably possible that changes in the values of investment securities will occur in the near term and that such changes could materially affect the amounts reported in the financial statements. Investment Valuation and Income Recognition - All investments are recorded at fair market value based on quoted market prices. Purchase and sale transactions are recorded on a trade date basis. Interest income is recorded on the accrual basis. Dividends are recorded on the ex-dividend date. Payment of Benefits - Benefit payments are recorded when paid. - 6 - 3. INVESTMENTS The fair market value of individual investments that represent five percent or more of the Plan's net assets are as follows as of December 31: 2001 2000 Newport News Shipbuilding Inc. Common Stock $ 82,136,810 $186,279,794 Northrop Grumman Corporation Common Stock 82,300,459 - Money Market Fund 292,490,942 179,872,388 Fidelity Growth Company Fund 103,332,434 137,720,350 Putnam New Opportunities Fund 66,053,066 93,625,671 Equity Index Fund 56,795,956 65,658,915 During 2001, the Plan's investments (including gains and losses on investments bought and sold, as well as on investments held during the year) appreciated (depreciated) in value as follows: 2001 Common stock $ 67,185,020 Mutual funds (12,914,827) Collective funds (60,395,776) ------------ Net depreciation $ (6,125,583) ============ 4. NONPARTICIPANT-DIRECTED INVESTMENTS Information about the net assets and the significant components of the changes in net assets relating to the nonparticipant-directed investment is as follows as of December 31: 2001 2000 Net Assets - Newport News Shipbuilding Inc. Common Stock $ - $186,279,794 Year Ended December 31, 2001 Changes in net assets: Net appreciation $ 40,959,717 Interest and dividends 745,571 Employer contributions 24,022,782 Participant contributions 2,444,879 Benefits paid to participants (7,465,701) Administrative expenses (12,513) ------------ Net appreciation $ 60,694,735 ============ - 7 - 5. TAX STATUS The Internal Revenue Service ("IRS") has determined and informed the Company by a letter, dated November 17, 1997, that the Plan and related trust were designed in accordance with the applicable regulations of the IRC. The Plan has been amended since receiving the IRS' Determination Letter; however, the Company and the plan administrator believe that the Plan is currently designed and operated in compliance with the applicable requirements of the IRC and the Plan and related trust continue to be tax exempt. Therefore, no provision for income taxes has been included in the Plan's financial statements. 6. PLAN TERMINATION Although it has not expressed any intention to do so, the Company has the right under the Plan to discontinue its contributions at any time and to terminate the Plan subject to the provisions set forth in ERISA. In the event that the Plan is terminated, participants would become 100 percent vested in their accounts. 7. TRANSACTIONS WITH PARTIES-IN-INTEREST Since the Company's and Northrop Grumman's common stock are investments held by the Plan, investments in these common stocks represented transactions with parties-in-interest. Certain plan investments are shares of collective funds managed by the Trustee. Therefore, transactions with these investments qualify as transactions with parties-in-interest. 8. PLAN AMENDMENTS The Plan was amended and restated on December 19, 2001, effective January 1, 2002, to provide for the Plan's compliance with specific tax and other regulatory requirements and to provide for new provisions in the Plan. The following significant changes in the Plan are effective for the plan year beginning January 1, 2002: o The limit on participant contributions was increased to 20 percent; o The three percent Company stock grant to participants' accounts was eliminated; and o The Company matching contribution was increased to one half of the first eight percent plus one quarter of the next four percent of a participant's compensation deferred under the Plan. 9. CONVERSION OF COMPANY COMMON STOCK As a result of the merger of the Company with and into Northrop Grumman, the Plan converted investments in NNS common stock to Northrop Grumman common stock. Participants were given the opportunity to exchange all their NNS shares for either $67.50 per share in cash or 0.7193 shares of Northrop Grumman common stock, subject to adjustment. This conversion occurred through a tender offer expiring on November 29, 2001 and a subsequent surrendering of NNS shares by participants in exchange for $67.50 per share in cash or 0.7193 shares of Northrop Grumman common stock. During early 2002 through a final conversion, all shares that had not been tendered resulted in the participants receiving $51.14 in cash and 0.1743 shares of Northrop Grumman common stock for each share of NNS common stock. - 8 - 10. ELIMINATION OF INVESTMENT OPTIONS During the year ended December 31, 2001 the Plan notified participants that it would eliminate the investment options related to former affiliates of the Company. Participants were provided with the option to redirect their balances in these investment options to other investment options provided for under the Plan. On January 2, 2002, all remaining investments related to former affiliates were liquidated and the proceeds were invested in money market funds. - 9 - NEWPORT NEWS SHIPBUILDING INC. 401(k) INVESTMENT PLAN FOR SALARIED EMPLOYEES SCHEDULE H, LINE 4i - SCHEDULE OF ASSETS (HELD AT END OF YEAR) DECEMBER 31, 2001 -------------------------------------------------------------------------------- Description of Investment, Identity of Issue, Including Maturity Date, Borrower, Lessor Rate of Interest, Collateral, Current or Similar Party Par or Maturity Value Value U.S. Bond Index Fund Collective Fund $ 14,946,840 Equity Index Fund Collective Fund 56,795,956 LifePath 2000* Collective Fund 1,097,237 LifePath 2010* Collective Fund 3,155,362 LifePath 2020* Collective Fund 4,928,159 LifePath 2030* Collective Fund 4,335,460 LifePath 2040* Collective Fund 7,906,253 Money Market Fund* Collective Fund 292,490,941 State Street Research International Mutual Fund Shares 675,100 State Street Aurora Fund Mutual Fund Shares 12,653,123 Van Kampen Growth and Income Fund Mutual Fund Shares 6,221,696 Putnam New Opportunities Fund Mutual Fund Shares 66,053,066 Templeton Foreign Fund Mutual Fund Shares 11,996,928 Fidelity Growth Company Fund Mutual Fund Shares 103,332,434 INVESCO Value Trust Total Return Fund Mutual Fund Shares 5,373,446 Northrop Grumman Common Stock* Common Stock 82,300,459 Newport News Shipbuilding Inc.
