Income (loss) from operations consists of sales less cost of sales, engineering and development expenses, and selling, general and administrative expenses but is not affected by either other income/expense or by income taxes expense (benefit). Non-operating expenses/income consists principally of investment income, interest income from transactions with payment terms exceeding one year (see Note 6 for details), and interest expense. All intercompany transactions have been eliminated.
