Comparable Companies — Comparable Companies (also called comparables or comps) are independent enterprises whose financial results are used to benchmark a tested party's profitability under the Transactional Net Margin Method (TNMM) or Comparable Profits Method (CPM).
Comparable Companies (also called comparables or comps) are independent enterprises whose financial results are used to benchmark a tested party's profitability under the Transactional Net Margin Method (TNMM) or Comparable Profits Method (CPM). A company is "comparable" when it performs similar functions, uses similar assets, and assumes similar risks as the tested party—making its profitability a reliable reference for arm's length pricing.
Comparable companies must be independent—they cannot be related parties or have controlled transactions that materially affect their profitability.
OECD/Regulatory Reference
The OECD Transfer Pricing Guidelines (2022) establish comparability as the cornerstone of transfer pricing analysis in Chapters I and III. The Guidelines define the five comparability factors: (1) characteristics of property or services transferred, (2) functions performed by the parties, (3) contractual terms, (4) economic circumstances of the parties, and (5) business strategies pursued.
The Guidelines note that identifying comparables requires a search for uncontrolled transactions whose characteristics are sufficiently similar to the controlled transaction.
US Treasury Regulations §1.482-1(d)(1) require that comparables be similar to the controlled transaction, mandating consideration of functions, risks, contractual terms, and economic conditions when evaluating comparability.
In Practice
Finding comparable companies involves a systematic search process:
Define search criteria based on the tested party's functions, industry, and geography
Query databases (Orbis, TP Catalyst, Amadeus, Compustat) using quantitative filters
Apply screening criteria (independence, revenue thresholds, data availability)
Manual review each potential comparable for functional similarity
Document accept/reject decisions for each company reviewed
Key Comparability Factors:
Factor
What to Match
Why It Matters
Functions
Similar activities performed
Functions drive profitability
Assets
Similar asset intensity
Asset base affects returns
Risks
Similar risk profile
Risk level affects required returns
Industry
Same or similar NACE/SIC codes
Industry norms differ
Geography
Same region/market
Economic conditions vary
Quality Over Quantity: 8 highly comparable companies is better than 25 loosely comparable ones. Tax authorities scrutinize comparable sets with weak functional similarity. Each comparable should be defensible as genuinely similar to the tested party.
Example
Tested Party: Limited-risk distributor of electronic components in Germany.

For a company to qualify as comparable, it must meet these standards:
Requirement
Test
Red Flags
Independence
No related-party transactions affecting results
Significant intercompany revenue
Functional similarity
Performs similar core functions
Different business model (e.g., manufacturer vs. distributor)
Financial data
Audited financials available
Unreliable or incomplete data
Ongoing business
Operating normally during period
Restructuring, bankruptcy, start-up
Clean profitability
No extraordinary items distorting results
One-time gains/losses, M&A effects
Manual Screening is Non-Negotiable: Databases can't assess functional comparability. Every company passing quantitative filters must be manually reviewed—read the business description, check for manufacturing vs. distribution, verify independence. Document your reasoning for each accept/reject decision.

Tested Party — The entity being benchmarked against comparables
While there's no universal minimum, 7–15 comparables is generally considered robust. Fewer than 5 comparables makes statistical measures less reliable and may raise tax authority concerns. More important than count is quality—each comparable should genuinely match the tested party's functions. Some jurisdictions (e.g., Germany) have indicated preferences for minimum numbers.
Can I use companies from different countries?
Yes, regional comparables are acceptable when local comparables are insufficient or when the tested party operates in a pan-regional market. However, most tax authorities prefer local comparables when available. If using regional comparables, consider whether country risk adjustments are needed to account for economic differences. Document why regional expansion was necessary.
Should I exclude loss-making comparables?
Generally, persistent loss-makers should be excluded unless losses are explained by normal business factors (economic downturn, start-up phase, market exit) that also apply to your tested party. A company consistently unprofitable over 3+ years may have structural issues unrelated to the tested transaction. However, don't exclude losses in cyclical industries during downturns—that would bias results upward.
What independence indicators should I use?
For Bureau van Dijk databases (Orbis, Amadeus), use BvD Independence Indicators:
A = No shareholder with >25% ownership (most independent)
B = No shareholder with >50% ownership
C = No shareholder with >50%, but below threshold for A/B
Typically, accept A and B; C may require additional verification. Exclude D (>50% owned) and U (unknown).
How do I handle companies with multiple business lines?
If a potential comparable has significant activities outside the tested function (e.g., a distributor that also manufactures), you have options: (1) exclude it if non-comparable activities materially affect profitability, (2) use segmented financials if reported separately, or (3) include it with documented caveats. Segmented data is ideal but often unavailable for private companies.
Can I use the same comparable set for multiple years?
Yes, using a consistent comparable set across analysis years is preferred and demonstrates robustness. Update the set only when comparables no longer meet criteria (bankruptcy, acquisition, business model change). Recalculate comparables' PLIs annually using their financial data for each year. Don't re-run the search every year to optimize results.
What if my tested party is unique in the market?
If no reliable comparables exist, consider: (1) expanding the geographic search, (2) using companies with similar functions even if different industries, (3) applying the Profit Split Method which doesn't require external comparables, or (4) using CUP method if comparable transactions exist. Document the search effort thoroughly—"no comparables found" requires strong justification.
