To show that a related-party price is arm's length, you have to measure it against something, and that is what transfer pricing methods do. There are five recognised methods, drawn from the international standards the UAE follows. They are not a menu to pick from by preference. The rule is to use the most appropriate method for the transaction, and knowing what each does, and when it fits, is how a group defends its pricing rather than just asserting it.
The comparable uncontrolled price method
The comparable uncontrolled price method, or CUP, is the most direct. It compares the price charged in the related-party transaction with the price charged in a comparable transaction between independent parties. Where a genuine comparable exists, for example a commodity with a market price or the same product sold to third parties, CUP is powerful because it tests price against price. Its weakness is that truly comparable independent transactions are often hard to find, especially for services and unique goods.
Resale price and cost plus
Where CUP is not available, two gross-margin methods often help. The resale price method starts from the price at which a product bought from a related party is resold to an independent customer, and works back by an arm's length gross margin. It suits distributors. The cost plus method starts from the costs a supplier incurs and adds an arm's length mark-up. It suits manufacturers and service providers that add value to inputs. Both test the margin earned rather than the price itself.
The profit-based methods
The transactional net margin method, or TNMM, compares the net profit margin the tested party earns on a transaction with the margins independent companies earn on comparable activity. It is widely used because net margins are more robust to product differences than gross ones, and comparable data is more available. The profit split method divides the combined profit of the related parties according to how independent parties would have shared it, and it fits highly integrated operations or those with valuable shared intangibles, where neither side can be tested in isolation.
Most appropriate, not most convenient
The regime does not rank the methods rigidly, but it does require you to select the one most appropriate to the facts, considering the nature of the transaction, the functions performed, and the availability of reliable comparables. A method chosen because it produces a convenient answer, rather than because it fits the transaction, is exposed. The selection itself is part of the analysis, and the file should explain why the chosen method beats the alternatives, not just apply it.
What to do about it
For each material related-party transaction, work through the methods and choose the most appropriate on the facts, documenting why. Prefer a direct price comparison where a real comparable exists, and fall back to margin or profit-based methods where it does not. Match the method to the party being tested and the value it adds. And keep the reasoning, because the choice of method is one of the first things a review will probe. The right method, well justified, turns a price into a defensible position.
