“ 68. The five methods stipulated in sub-section ( 1) of section 92C, are set out and articulated step-wise in detail in rule 10B of the Rules. Be it any of the five methods, the first step to be exercised is to identify the international transaction and the transfer price paid for the same by two associated enterprises. The second step is to carry out functional analysis, i.e., the functions to be performed by the two associated enterprises taking into account the assets used, risk assumed, the contractual terms, the economic circumstances of the parties and the business strategy pursued by the parties. On the question of comparability analysis, the United Nations' Practical Manual on Transfer Pricing in paragraph 5 .1.1 states that the analysis is used to designate two distinct but related analytical steps. First being to understand the economic significant characteristic of the controlled transaction between the two associated enterprises and the respective roles of the parties thereto. This has reference to the 5 characteristics, i.e., (a) characteristic of property or services transferred; (b) functions performed by the parties taking into account assets employed and risk assumed, i.e., functional analysis ; (c) contractual terms ; (d) economic circumstances and (e) business strategies pursued. The second analytical steps is comparison of those conditions of the controlled transactions with uncontrolled transactions, i.e., transactions between the two associated enterprises taking into account the economically significant characteristics of the controlled transactions and the respective roles of the 5 comparability factors. The aforesaid analysis, therefore, requires selection of appropriate comparables, i.e., an uncontrolled transaction which is to be compared with a tested party. The comparables can be internal, i.e., when one of the associated enterprises enters into a similar uncontrolled transaction with an independent enterprise ; or external, i.e., involving an independent enterprise in the same market or industry. It is obvious that an internal comparable could in several cases be more dependable and reliable than an external comparable. A comparable is acceptable, if based upon comparison of conditions a controlled transaction is similar with the conditions in the transactions between independent enterprises. The comparison must be with reference to the comparability analysis as elucidated in paragraph 5.1.1 of the United Nations Practical Manual on Transfer Pricing. In other words, the economically relevant characteristics of the two transactions being compared must be sufficiently comparable. This entails and implies that difference, if any, between controlled and uncontrolled transaction, should not materially affect the conditions being examined given the methodology being adopted for determining the price or the margin. When this is not possible, it should be ascertained whether reasonably accurate adjustments can be made to eliminate the effect of such differences on the price or margin. Thus, identification of the potential comparables is the key to the transfer pricing analysis. As a sequitur, it follows that the choice of the most
