(A) The specified method requirement is met if the taxpayer selects and applies a specified method in a reasonable manner. The taxpayer's selection and application of a specified method is reasonable only if, given the available data and the applicable pricing methods, the taxpayer reasonably concluded that the method (and its application of that method) provided the most reliable measure of an arm's length result under the principles of the best method rule of § 1.482-1(c). A taxpayer can reasonably conclude that a specified method provided the most reliable measure of an arm's length result only if it has made a reasonable effort to evaluate the potential applicability of the other specified methods in a manner consistent with the principles of the best method rule. The extent of this evaluation generally will depend on the nature of the available data, and it may vary from case to case and from method to method. This evaluation may not entail an exhaustive analysis or detailed application of each method. Rather, after a reasonably thorough search for relevant data, the taxpayer should consider which method would provide the most reliable measure of an arm's length result given that data. The nature of the available data may enable the taxpayer to conclude reasonably that a particular specified method provides a more reliable measure of an arm's length result than one or more of the other specified methods, and accordingly no further consideration of such other specified methods is needed. Further, it is not necessary for a taxpayer to conclude that the selected specified method provides a more reliable measure of an arm's length result than any unspecified method. For examples illustrating the selection of a specified method consistent with this paragraph (d)(2)(ii), see § 1.482-8. Whether the taxpayer's conclusion was reasonable must be determined from all the facts and circumstances. The factors relevant to this determination include the following:
(1) The experience and knowledge of the taxpayer, including all members of the taxpayer's controlled group.
(2) The extent to which reliable data was available and the data was analyzed in a reasonable manner. A taxpayer must engage in a reasonably thorough search for the data necessary to determine which method should be selected and how it should be applied. In determining the scope of a reasonably thorough search for data, the expense of additional efforts to locate new data may be weighed against the likelihood of finding additional data that would improve the reliability of the results and the amount by which any new data would change the taxpayer's taxable income. Furthermore, a taxpayer must use the most current reliable data that is available before the end of the taxable year in question. Although the taxpayer is not required to search for relevant data after the end of the taxable year, the taxpayer must maintain as a principal document described in paragraph (d)(2)(iii)(B)(9) of this section any relevant data it obtains after the end of the taxable year but before the return is filed, if that data would help determine whether the taxpayer has reported its true taxable income.
(3) The extent to which the taxpayer followed the relevant requirements set forth in regulations under section 482 with respect to the application of the method.
(4) The extent to which the taxpayer reasonably relied on a study or other analysis performed by a professional qualified to conduct such a study or analysis, including an attorney, accountant, or economist. Whether the professional is an employee of, or related to, the taxpayer is not determinative in evaluating the reliability of that study or analysis, as long as the study or analysis is objective, thorough, and well reasoned. Such reliance is reasonable only if the taxpayer disclosed to the professional all relevant information regarding the controlled transactions at issue. A study or analysis that was reasonably relied upon in a prior year may reasonably be relied upon in the current year if the relevant facts and circumstances have not changed or if the study or analysis has been appropriately modified to reflect any change in facts and circumstances.
(5) If the taxpayer attempted to determine an arm's length result by using more than one uncontrolled comparable, whether the taxpayer arbitrarily selected a result that corresponds to an extreme point in the range of results derived from the uncontrolled comparables. Such a result generally would not likely be closest to an arm's length result. If the uncontrolled comparables that the taxpayer uses to determine an arm's length result are described in § 1.482-1(e)(2)(iii)(B), one reasonable method of selecting a point in the range would be that provided in § 1.482-1(e)(3).
(6) The extent to which the taxpayer relied on a transfer pricing methodology developed and applied pursuant to an Advance Pricing Agreement for a prior taxable year, or specifically approved by the Internal Revenue Service pursuant to a transfer pricing audit of the transactions at issue for a prior taxable year, provided that the taxpayer applied the approved method reasonably and consistently with its prior application, and the facts and circumstances surrounding the use of the method have not materially changed since the time of the IRS's action, or if the facts and circumstances have changed in a way that materially affects the reliability of the results, the taxpayer makes appropriate adjustments to reflect such changes.
(7) The size of a net transfer pricing adjustment in relation to the size of the controlled transaction out of which the adjustment arose.
(B) Services cost method. A taxpayer's selection of the services cost method for certain services, described in § 1.482-9(b), and its application of that method to a controlled services transaction will be considered reasonable for purposes of the specified method requirement only if the taxpayer reasonably allocated and apportioned costs in accordance with § 1.482-9(k), and reasonably concluded that the controlled services transaction satisfies the requirements described in § 1.482-9(b)(2). Whether the taxpayer's conclusion was reasonable must be determined from all the facts and circumstances. The factors relevant to this determination include those described in paragraph (d)(2)(ii)(A) of this section, to the extent applicable.
