GENERAL PLAN PROVISIONS The TRW Canada Stock Savings Plan [the "Plan"] is a qualified employee profit sharing and retirement savings plan sponsored by TRW Canada Limited. The Plan was originally established effective January 1, 1968 as a stock savings plan. Effective January 1, 1990, the Plan was amended to immediately vest TRW Canada Limited's contributions and the group retirement savings portion was added to the Plan. The eligibility of employees to participate in the Plan is based on the provisions as included in the Plan document. A participant may join the Plan upon becoming a permanent part-time or full-time employee. The provisions of the Plan require certain employees to have been employed for a period of 90 days before joining the Plan. The Plan's assets are held by Clarica Trust as Trustee and administrator of the Plan. Effective December 11, 2002, TRW Inc. ["TRW"] was acquired by Northrop Grumman Corporation ["NGC"] and TRW shares held in the Plan were converted into shares of NGC common stock based on a ratio of 0.5357 NGC share per TRW share. In connection with the acquisition of TRW by NGC, the Plan was amended to provide that any NGC common stock held in the Plan on March 1, 2003 would be distributed to participants in the form of share certificates. The investment programs of the Plan are as follows: Participant contributions Upon enrolment or re-enrolment, each participant directs that his/her basic contributions [computed in increments of one percent, from one percent to six percent of qualifying compensation] are to be invested in a range of professionally managed funds with different objectives, risk factors and return expectations. A participant may, at any time, change his/her contribution rate, temporarily suspend contributions, the way he/she invests future contributions or existing assets at any time, at no cost. If a participant temporarily suspends contributions, TRW Canada Limited's matching contributions [see TRW Canada Limited's contributions below] are also temporarily suspended. A participant may make cash withdrawals from his/her accounts at any time. However, if the participant withdraws his/her basic contribution or TRW Canada Limited's matching contribution made on or after January 1, 2003, the participant will not be able to contribute to the Plan or receive TRW Canada Limited's matching contribution for a period of three months. 1 The TRW Canada Stock Savings Plan NOTES TO FINANCIAL STATEMENTS December 31, 2002 TRW Canada Limited's contributions TRW Canada Limited shall contribute cash to the Plan for each month, out of current or accumulated earnings, an amount equal to 50% of the participant contributions [to a maximum of 3% of the participant's compensation] for such month. TRW Canada Limited's contributions vest immediately. All TRW Canada Limited's cash contributions were invested in TRW stock purchased on the open market up until December 11, 2002 at which point the sponsor contributions were directed to Clarica Perigee Axis Cash Fund NR. The number of participants in each of the funds at December 31 is as follows: 2002 2001 -------------------------------------------------------------------------------- Clarica Trimark Equity Fund NR [Non-registered] 4 -- Clarica Trimark Global Fund NR 3 -- Clarica McLean Budden Canadian Equity Growth Fund NR 5 -- Clarica McLean Budden Bond Fund NR 6 -- Clarica McLean Budden Core Balanced Fund NR 7 -- Clarica Perigee Axis Cash Fund NR 493 -- Clarica US Equity Index Fund NR 2 -- NGC common stock 528 -- Clarica CC&L Balanced Fund 9 -- Clarica Trimark Equity Fund 15 -- Clarica Perigee International Fund 8 -- Clarica Trimark Global Fund 22 -- Clarica Synthetic US Equity Index Fund 12 -- Clarica McLean Budden Canadian Equity Growth Fund 14 -- Clarica McLean Budden Bond Fund 12 -- Clarica McLean Budden Core Balanced Fund 128 -- Clarica Perigee Axis Cash Fund 50 -- TRW Stock Fund -- 511 Pooled Money Market Fund Employees' Profit Sharing Plan -- 92 Pooled Balanced Fund Registered Retirement Savings Plan -- 131 Pooled Money Market Fund Registered Retirement Savings Plan -- 54 -------------------------------------------------------------------------------- The total number of participants in the Plan is less than the sum of the number of participants shown above because many are participating in more than one fund. 2 The TRW Canada Stock Savings Plan NOTES TO FINANCIAL STATEMENTS December 31, 2002 2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES These financial statements have been prepared in accordance with Canadian generally accepted accounting principles, within the framework of the significant accounting policies summarized below: Basis of accounting The accompanying financial statements have been prepared on the accrual basis of accounting. 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 settlement date basis. Interest income is recorded on the accrual basis. Unrealized appreciation or depreciation of investments is the difference between the current value and the cost of investments. The realized gain or loss on investments is the difference between the proceeds received and the average cost of investments sold. Payment of benefits Benefit payments are recorded when paid. Gains or losses on investments The realized gains or losses on disposition or transfer of an investment is determined from the market value of the investment at the date of disposition or transfer and the average cost base of that specific pool of investments prior to the disposition or transfer. Unrealized gains or losses are determined as the net effect of the change in appreciation (depreciation) of investments from January 1 to December 31, based on market value and the average cost base of each investment at those respective dates. Income recognition Dividend income is recognized as earned. Interest income is recognized as it is earned consistent with the accrual basis of accounting. 3 The TRW Canada Stock Savings Plan NOTES TO FINANCIAL STATEMENTS December 31, 2002 3. INCOME TAXES The Plan is exempt from Canadian federal income taxes under the provisions of the Income Tax Act (Canada) [the "Act"]. Federal income tax consequences to the participants under the Plan are as provided in the Act. TRW Canada Limited's contributions are taxable to the participants as is the income and all post-1971 capital gains, less post-1971 capital losses of the Plan, all of which are allocated to the participants by the Trustee during the year, whether or not such amounts are paid to the participants by the Trustee during the year. The amount of foreign non-business income taxes paid on foreign source income by the trusts under the Plan for the year is allocated to and deemed to have been paid by the participants for Canadian federal income tax purposes. Participants who are non-resident taxpayers are subject to special rules depending on whether they have performed duties in Canada during the year and are subject to withholding tax on amounts paid or credited to them under the Plan. 4. RELATED PARTY TRANSACTIONS All expenses related to the Plan are paid by TRW Canada Limited. 5. STATEMENT DISCLOSURES The costs of the investments have not been shown parenthetically as cost is not tracked or disclosed by the Trustee when reporting to us. The realized and unrealized gains and losses have not been disclosed separately as the Trustee does not segregate this information when reporting to us. 6. COMPARATIVE FINANCIAL STATEMENTS The comparative financial statements have been reclassified from statements previously presented to conform to the presentation of the 2002 financial statements. 7. UNITED STATES GENERALLY ACCEPTED ACCOUNTING PRINCIPLES The Plan's accounting policies do not materially differ from United States generally accepted accounting principles. 4 SIGNATURES The Plan.
