SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES These financial statements have been prepared in accordance with accounting principles generally accepted in Canada, and are within the framework of the accounting policies summarized below. Gains and 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 Dividends are recognized as earned. Interest income is recognized as it is earned consistent with the accrual basis of accounting. 2 The TRW Canada Stock Savings Plan NOTES TO FINANCIAL STATEMENTS December 31, 1999 and 1998 3. INCOME TAXES The Plan is exempt from Canadian federal income taxes under provisions of the Income Tax Act. Federal income tax consequences to the participants under the Plan are as provided in the Income Tax Act. TRW Canada Limited 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. In some circumstances, the amounts taxable could exceed the amounts allocated. The amount of foreign non-business income tax 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 15% withholding tax on amounts paid or credited to them under the Plan. 4.
