Comparability Analysis
Comparability analysis identifies and evaluates the economically relevant characteristics of a controlled transaction and compares them with uncontrolled transactions to assess similarity for benchmarking. The OECD identifies five factors: contractual terms, functions, characteristics, economic circumstances, and strategies.
A thorough comparability analysis begins with understanding the controlled transaction through accurate delineation, examining actual conduct rather than written contracts, before searching for comparables sharing similar characteristics. Material differences must be adjusted for or the comparable must be excluded.
The depth required varies by method, since traditional methods such as CUP demand close comparability, while profit methods such as TNMM tolerate broader differences. Robust documentation of the search process and rejection criteria applied is essential to demonstrate genuine arm's length conditions were met.
In practice
What matters when applying comparability analysis
- Assesses five OECD comparability factors
- Begins with accurate delineation of the transaction
- Differences must be adjusted for or excluded
- Depth of analysis varies by method chosen
- Documentation of the search process is essential
Frequently asked
Common questions
What are the five comparability factors identified by the OECD?+
The five comparability factors are the contractual terms of the transaction, the functions performed by each party taking into account assets used and risks assumed, the characteristics of the property transferred or services provided, the economic circumstances of the parties and markets involved, and the business strategies pursued, such as market penetration or diversification strategies that may temporarily affect profitability.
What happens if a comparable has material differences from the tested party?+
If a potential comparable shows material differences in one or more comparability factors, a reliable adjustment should be made to eliminate the effect of that difference wherever possible, for example a working capital adjustment for differing payment terms. If no reliable adjustment can be made, the comparable should generally be rejected from the benchmarking set rather than included with an unquantified distortion.
