In some cases, the assets of an uncontrolled comparable may need to be adjusted to achieve greater comparability between the tested party and the uncontrolled comparable. In such cases, the uncontrolled comparable’s operating income attributable to those assets must also be adjusted before computing a profit level indicator in order to reflect the income and expense attributable to the adjusted assets. In certain cases it may also be appropriate to adjust the operating profit of the tested party and comparable parties.
