Arm's Length Range
The arm's length range is the span of financial results, whether prices, margins or returns, produced by a set of properly selected comparable companies or transactions. Any outcome falling within this range is generally accepted as consistent with the arm's length principle, meaning no further pricing adjustment is required.
Building an arm's length range starts with identifying comparable companies or transactions through a rigorous comparability analysis covering function, risk, contractual terms and market conditions. The financial results from these comparables, often measured over several years, are then compiled into a data set.
Once the range is established, the taxpayer's actual result is tested against it. If the result sits within the accepted range, most tax authorities will not seek an adjustment, though the OECD Guidelines note that a point closer to the median may still be favoured where comparability is imperfect. If the result falls outside.
In practice
What matters when applying arm's length range
- Represents acceptable pricing outcomes from comparable data
- Built from a properly conducted comparability analysis
- Often narrowed using the interquartile range method
- Results outside the range attract closer scrutiny
- Median is frequently used as the fallback adjustment point
Frequently asked
Common questions
How wide can an arm's length range be?+
There is no fixed width because it depends entirely on the quality and consistency of the comparable data used. A tight cluster of highly comparable companies produces a narrow range, while a broader or less reliable comparable set produces a wider one.
What happens if actual results fall outside the arm's length range?+
Falling outside the range signals that the controlled transaction's pricing may not reflect market conditions, which can trigger a transfer pricing adjustment by the tax authority. In many jurisdictions, the adjustment defaults to the median of the range unless the taxpayer can demonstrate that another point is more appropriate given specific facts.
