Reliability.
(ii) Reliability. If an uncontrolled transaction involves the transfer of the same intangible under the same, or substantially the same, circumstances as the controlled transaction, the results derived from applying the comparable uncontrolled transaction method will generally be the most direct and reliable measure of the arm's length result for the controlled transfer of an intangible. Circumstances between the controlled and uncontrolled transactions will be considered substantially the same if there are at most only minor differences that have a definite and reasonably ascertainable effect on the amount charged and for which appropriate adjustments are made. If such uncontrolled transactions cannot be identified, uncontrolled transactions that involve the transfer of comparable intangibles under comparable circumstances may be used to apply this method, but the reliability of the analysis will be reduced.
