Transfer Pricing Comparables: Functional vs. Product Comparability
Transfer pricing comparables are independent companies or transactions used to test whether intercompany pricing meets the arm’s-length principle — the requirement that related-party transactions be priced as if the parties were unrelated. A common point of confusion: comparables don’t need to sell the same products as your business. For the transactional net margin method (TNMM) and comparable profits method (CPM), what matters is functional comparability — similar functions, assets, and risks (FAR) — not product similarity. This article explains why, with practical examples, and how Exactera helps identify functionally comparable companies.
The Common Misconception: “Why Aren’t My Comparables My Competitors?
If you’re new to transfer pricing, this is one of the most common questions: why aren’t the comparable companies in my benchmarking report my actual competitors? Here’s the short answer — and the longer explanation.
If I had a dollar for every time I’ve heard someone who’s new to transfer pricing ask me why the comparable companies in one of their reports are not their local competitors…I wouldn’t be writing this blog (or at least I’d be writing it on the beach). Given this, I thought I’d share my explanation here.
Functional Comparability: What Actually Drives Profit Margins
When benchmarking the profitability of a tested party using the transactional net margin method (TNMM) or comparable profits method (CPM) — among the most commonly used transfer pricing methods — product comparability takes a back seat to functional comparability. This is because a company’s Functions, Assets, and Risks (FAR) are what create its profit margin, not the specific products it sells. A comparable that performs the same functions, uses similar assets, and bears similar risks as your tested party will tend to earn a similar margin — regardless of what it sells.
Two Examples: When Product Type Doesn’t Matter — and When It Does
Example 1: Distributors selling different products
Let’s look at distributors as an example. Regardless of the products they sell, distributors have specific functions — inventory management, logistics, and marketing — that drive their ability to generate revenue and control costs. These functions have a direct impact on the profit margin. Similarly, receivables risk and physical assets such as warehousing are also key to a distributor’s margin. Whether the particular distributor is selling plumbing products or office furniture, these characteristics remain consistent — making them potentially valid comparables for each other.
Example 2: When product type does matter
Granted, certain products are ‘unique’ enough to require comparables within the same industry — and in certain circumstances, that’s the correct approach. For instance, if your tested party is a frozen-food distributor, which requires storage conditions very different from our plumbing supply example, you’d want to find comparable distribution companies that similarly deal with frozen (or at least fresh) foods.
The important point: we would reject a comparable that manufactures frozen foods but accept a comparable that only distributes coffee and other dry foods. Why? Because the frozen-food manufacturer has very different functional characteristics that will impact its margin — we’d be comparing apples to oranges (food pun intended). In other words, while the product comparability of the coffee distributor isn’t optimal, its margin is a much better comparison of what our tested party should be earning. This is an application of one specific comparability factor — Functions — which we’ll place in context next.
How Exactera Identifies Functionally Comparable Companies
We applied this very concept when we structured our transfer pricing benchmark search engine. It specifically focuses on the function of the tested party, and returns functionally similar comparables, rather than rely on industry codes or keywords, which offer a much weaker correlation to functional characteristics and require much trial and error by the user to come up with a decent set of comps.
