Operating expenses
(3) Operating expenses includes all expenses not included in cost of goods sold except for interest expense, foreign income taxes (as defined in 1.901-2(a)), domestic income taxes, and any other expenses not related to the operation of the relevant business activity. Operating expenses ordinarily include expenses associated with advertising, promotion, sales, marketing, warehousing and distribution, administration, and a reasonable allowance for depreciation and amortization. (4) Operating profit means gross profit less operating expenses. Operating profit includes all income derived from the business activity being evaluated by the comparable profits method, but does not include interest and dividends, income derived from activities not being tested by this method, or extraordinary gains and losses that do not relate to the continuing operations of the tested party. (5) Reported operating profit means the operating profit of the tested party reflected on a timely filed U.S. income tax return. If the tested party files a U.S. income tax return, its operating profit is considered reflected on a U.S. income tax return if the calculation of taxable income on its return for the taxable year takes into account the income attributable to the controlled transaction under review. If the tested party does not file a U.S. income tax return, its operating profit is considered reflected on a U.S. income tax return in any taxable year for which income attributable to the controlled transaction under review affects the calculation of the U.S. taxable income of any other member of the same controlled group. If the comparable operating profit of the tested party is determined from profit level indicators derived from financial statements or other accounting records and reports of comparable parties, adjustments may be made to the reported operating profit of the tested party in order to account for material differences between the tested party's operating profit reported for U.S income tax purposes and the tested party's operating profit for financial statement purposes. In addition, in accordance with 1.482-1(f)(2)(iii)(D), adjustments under section 482 that are finally determined may be taken into account in determining reported operating profit. (6) Operating assets. The term operating assets means the value of all assets used in the relevant business activity of the tested party, including fixed assets and current assets (such as cash, cash equivalents, accounts receivable, and inventories).
