Comparability and reliability considerations

(c)Comparability and reliability considerations—(1) In general. Whether results derived from application of this method are the most reliable measure of the arm's length result must be determined using the factors described under the best method rule in § 1.482-1(c).

(2)Comparability—(i) In general. The degree of comparability between an uncontrolled taxpayer and the tested party is determined by applying the provisions of § 1.482-1(d)(2). The comparable profits method compares the profitability of the tested party, measured by a profit level indicator (generally based on operating profit), to the profitability of uncontrolled taxpayers in similar circumstances. As with all methods that rely on external market benchmarks, the greater the degree of comparability between the tested party and the uncontrolled taxpayer, the more reliable will be the results derived from the application of this method. The determination of the degree of comparability between the tested party and the uncontrolled taxpayer depends upon all the relevant facts and circumstances, including the relevant lines of business, the product or service markets involved, the asset composition employed (including the nature and quantity of tangible assets, intangible assets and working capital), the size and scope of operations, and the stage in a business or product cycle.

(ii)Functional, risk and resource comparability. An operating profit represents a return for the investment of resources and assumption of risks. Therefore, although all of the factors described in § 1.482-1(d)(3) must be considered, comparability under this method is particularly dependent on resources employed and risks assumed. Moreover, because resources and risks usually are directly related to functions performed, it is also important to consider functions performed in determining the degree of comparability between the tested party and an uncontrolled taxpayer. The degree of functional comparability required to obtain a reliable result under the comparable profits method, however, is generally less than that required under the resale price or cost plus methods. For example, because differences in functions performed often are reflected in operating expenses, taxpayers performing different functions may have very different gross profit margins but earn similar levels of operating profit.

(iii)Other comparability factors. Other factors listed in § 1.482-1(d)(3) also may be particularly relevant under the comparable profits method. Because operating profit usually is less sensitive than gross profit to product differences, reliability under the comparable profits method is not as dependent on product similarity as the resale price or cost plus method. However, the reliability of profitability measures based on operating profit may be adversely affected by factors that have less effect on results under the comparable uncontrolled price, resale price, and cost plus methods. For example, operating profit may be affected by varying cost structures (as reflected, for example, in the age of plant and equipment), differences in business experience (such as whether the business is in a start-up phase or is mature), or differences in management efficiency (as indicated, for example, by objective evidence such as expanding or contracting sales or executive compensation over time). Accordingly, if material differences in these factors are identified based on objective evidence, the reliability of the analysis may be affected.

(iv)Adjustments for the differences between the tested party and the uncontrolled taxpayers. If there are differences between the tested party and an uncontrolled comparable that would materially affect the profits determined under the relevant profit level indicator, adjustments should be made according to the comparability provisions of § 1.482-1(d)(2). 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. For example, where there are material differences in accounts payable among the comparable parties and the tested party, it will generally be appropriate to adjust the operating profit of each party by increasing it to reflect an imputed interest charge on each party's accounts payable. As another example, it may be appropriate to adjust the operating profit of a party to account for material differences in the utilization of or accounting for stock-based compensation (as defined by § 1.482-7(d)(3)(i)) among the tested party and comparable parties.

(3)Data and assumptions—(i) In general. The reliability of the results derived from the comparable profits method is affected by the quality of the data and assumptions used to apply this method.

(ii)Consistency in accounting. The degree of consistency in accounting practices between the controlled transaction and the uncontrolled comparables that materially affect operating profit affects the reliability of the result. Thus, for example, if differences in inventory and other cost accounting practices would materially affect operating profit, the ability to make reliable adjustments for such differences would affect the reliability of the results.

(iii)Allocations between the relevant business activity and other activities. The reliability of the allocation of costs, income, and assets between the relevant business activity and other activities of the tested party or an uncontrolled comparable will affect the reliability of the determination of operating profit and profit level indicators. If it is not possible to allocate costs, income, and assets directly based on factual relationships, a reasonable allocation formula may be used. To the extent direct allocations are not made, the reliability of the results derived from the application of this method is reduced relative to the results of a method that requires fewer allocations of costs, income, and assets. Similarly, the reliability of the results derived from the application of this method is affected by the extent to which it is possible to apply the profit level indicator to the tested party's financial data that is related solely to the controlled transactions. For example, if the relevant business activity is the assembly of components purchased from both controlled and uncontrolled suppliers, it may not be possible to apply the profit level indicator solely to financial data related to the controlled transactions. In such a case, the reliability of the results derived from the application of this method will be reduced.
