Why should you care about a company's transactions with itself?

A company announces that it has sold equipment to an affiliate for $50 million, or hired consulting services from a firm owned by the CEO's family for $10 million annually, or bought components from a supplier that is 30% owned by the board's largest shareholder.

At first glance, these might seem like ordinary business transactions. Companies buy and sell with many counterparties. What matters is price and value.

But related-party transactions—deals between a company and its insiders, affiliated entities, or entities with overlapping ownership—are where fraud often hides. Because there is no arm's-length negotiation, no competitive pressure, and no natural incentive for both sides to strike a fair deal. Instead, one side can extract hidden value from the other.

A company can overpay a related party (funneling profit to an insider). Or underpay (siphoning assets out). Or the transaction might be between a parent and subsidiary, disguising profits or losses to manipulate reported earnings.

This article explores the red flags hidden in related-party transactions, how to find them in the footnotes, and what they reveal about management integrity.

Quick definition​

A related-party transaction is any transaction between a company and an entity that has a relationship to the company or its insiders. The relationship can be ownership (a subsidiary, joint venture, or affiliate), control (an entity owned by the CEO or a director), family ties (a company owned by an insider's relative), or common management. Related-party transactions must be disclosed in a footnote (or, on a 10-K, in Item 13 of the 10-K and Item 14 of the proxy statement).

Key takeaways​

  • Related-party transactions are inherently suspect because there is no arm's-length bargaining. Prices can be inflated, deflated, or terms hidden.
  • The SEC requires extensive disclosure of related-party transactions, but disclosure alone does not prevent abuse—it just requires honesty about conflicts.
  • Watch for round-dollar amounts, vague descriptions ("consulting services," "management fees"), and transactions that lack clear economic substance.
  • When related-party transactions are material to a company's earnings or cash flow, or when they are hidden or downplayed, suspect earnings manipulation.
  • Common red flags: payments to entities controlled by insiders, transactions at prices that differ materially from market rates, or transactions that seem to lack independent business rationale.
  • The presence of a related-party transaction does not prove fraud, but it raises the risk. Combine it with other red flags for a more complete picture.

The core issue: When a transaction is between related parties, one side controls (or influences) both sides of the deal. This breaks the natural check that arm's-length dealing provides.

In a normal market transaction, a buyer wants to pay as little as possible, and a seller wants to receive as much as possible. The two incentives collide, and price emerges. If the price is wrong, one side can walk away.

In a related-party transaction, the incentives are aligned toward one goal: shifting value. An insider who controls both the buyer and seller can set the price anywhere they like. They might overpay the related party to extract profit (if the related party belongs to them or their family). Or underpay to siphon value out of the company (if they control the company but not the related party, or vice versa).

The board is supposed to review related-party transactions for fairness, but boards are often weak or captured by insiders. Auditors review them, but auditing is not forensic.

Common structures and red flags​

Overpayment to related parties (extracting profit from the company)

A company pays a consulting firm (owned by the CEO) $5 million annually for "strategic advice." The work is vague, deliverables are unclear, and the fee far exceeds market rates for consulting. The CEO is extracting profit from the company and moving it into their own entity.

Red flags:

  • Large, growing payments to related parties.
  • Vague descriptions of what the related party is doing.
  • No competitive bidding or external validation of the fee.
  • The CEO or major shareholder has a direct or indirect ownership stake in the related party.

Asset transfers at inflated prices (extracting equity)

A company sells intellectual property (patents, trademarks) to a related entity (controlled by an insider) at a discounted price, or transfers the asset at an inflated valuation, then the related entity sells it back to the company or a third party at a higher price. The insider captures the difference.

Red flags:

  • Asset transfers between the company and related entities at prices that differ from recent independent valuations.
  • A "strategic sale" of an asset to a related party, followed by a buyback at a higher price or write-down by the company.
  • Vague or aggressive intangible asset valuations involved in the transaction.

Cost-shifting through transfer pricing (moving profits)

A parent company sells products to a subsidiary (also controlled by the parent) at a markup, shifting profits to whichever entity has lower tax rates or is in a jurisdiction with favorable rules. The transfer price is inflated or deflated compared to market rates.

Red flags:

  • Significant related-party sales between parent and subsidiaries.
  • Transfer prices that are not publicly benchmarked or independently validated.
  • Sudden changes in related-party pricing or transaction volumes.
  • Large unrealized intercompany profits (inventory held at inflated cost).

Loan guarantees and debt (hidden liabilities)

A company guarantees debt or loans of related-party entities, or extends loans to related parties at favorable terms. The company is taking on risk without obvious economic benefit.

Red flags:

  • Related-party loans that are unsecured or under-collateralized.
  • Loan terms (interest rate, maturity) that are more favorable than the company could obtain on the open market.
  • Large loan guarantees or contingent liabilities not prominently disclosed.
  • Loans to related parties that are regularly renewed or rolled over rather than repaid.

Equity transactions (dilution or hidden funding)

A company purchases equity in a related-party entity at a premium, or sells equity to a related party at a discount. Value is transferred without obvious business rationale.

Red flags:

  • Investments in related-party entities that are not consolidated and not at fair market value.
  • Acquisitions of or capital contributions to entities controlled by insiders.
  • Sudden large equity issuances that are promptly used to fund related-party transactions.

1. The footnote (Item 13 or specific disclosure)

In a 10-K, Item 13 ("Certain Relationships and Related Transactions") and Item 14 ("Principal Accountant Fees and Services") disclose related-party transactions. In a 10-Q, search the notes for "related-party" or "affiliated."

Read every line. Note:

  • Who the related party is and what the relationship is (board member, shareholder, controlled entity, family member).
  • The nature of the transaction.
  • The amounts and terms.
  • Whether the transaction was ratified by independent board committees or audit committee.

2. The proxy statement (DEF 14A)

The proxy (filed before the annual shareholder meeting) includes a detailed "Relationships and Related Transactions" section. This is often clearer and more complete than the 10-K footnote.

3. Scan the MD&A for major counterparties

If the MD&A mentions a major supplier, customer, or partner, check whether that entity is disclosed as a related party. If it is, flag it and read the footnote carefully.

4. Watch the balance sheet for intercompany balances

Look for "due to/from affiliates" or "advances to related parties" on the balance sheet. Large or growing balances suggest material related-party activity. In the footnote, understand what these balances represent and whether they are being settled.

5. Check segment disclosures for affiliate revenues

If a company reports segment data, affiliate sales are sometimes broken out. Large intra-company revenues (sales between the company and its affiliates) should be eliminated when understanding the consolidated business. If elimination is not clear, flag it.

Real-world example: Berkshire Hathaway subsidiaries​

Warren Buffett's Berkshire Hathaway has numerous related-party transactions, but they are extensively disclosed and often involve arm's-length terms (Berkshire is a conglomerate, so subsidiaries naturally transact with each other). The board has an independent audit committee, and Buffett has a long reputation for integrity.

This is a case where related-party transactions are transparent and the governance mitigates risk. Investors can see the terms and assess fairness.

Contrast with: A smaller company where the CEO owns 40% of the shares, sits on the board, and has a consulting contract with a related entity that pays him $2 million annually for undefined services. The board lacks independent oversight, and the arrangement has not been validated by third parties. This is a major red flag.

Common mistakes​

1. Assuming disclosure alone ensures fairness

Just because a related-party transaction is disclosed does not mean it is fair or arm's-length. Disclosure is the baseline. You still need to evaluate whether the price, terms, and business rationale make sense. Many frauds involved fully disclosed related-party transactions.

2. Ignoring "de minimis" related-party transactions

The SEC allows companies to skip disclosing related-party transactions below certain thresholds (roughly $120,000 for smaller filers). But a clever fraudster can structure multiple small transactions to stay below the threshold. If you see a pattern of small transactions with the same related party, add them up and ask why the company is fragmenting them.

3. Misunderstanding transfer pricing in multinational groups

Large multinationals necessarily transfer goods and services between jurisdictions. Transfer pricing is complex and subject to tax regulation. Not all transfer pricing is suspicious. But if a company's transfer prices have never been validated by a transfer-pricing study, or if they change suddenly without explanation, investigate further.

4. Forgetting to check if the related-party transaction was ratified by independent directors

The proxy or footnote might note that a related-party transaction was reviewed and approved by an "independent committee" or "audit committee." This is a mitigating factor—it means insiders did not have sole control over the decision. But check whether the "independent" committee is truly independent (no financial ties to the insider beyond board compensation).

5. Assuming all related-party transactions are revenue-related

Some of the biggest red flags are on the balance sheet: loans to related parties, guarantees, equity investments. These are less visible than revenue or expense transactions, but they are where hidden liabilities lurk.

FAQ​

Q: Are all related-party transactions red flags?

A: No. Large conglomerates have extensive related-party transactions. If a parent company owns multiple operating subsidiaries, they transact with each other. As long as transactions are at fair market value and disclosed, they are fine. The red flag arises when terms are inflated, deflated, or hidden.

Q: What is a "fair" price for a related-party transaction?

A: Ideally, the same price that would be struck in an arm's-length transaction with an unrelated third party. This can be validated by: (1) third-party pricing (if comparable transactions exist), (2) independent appraisal, (3) competitive bidding, or (4) audit firm review. If none of these exist, the transaction is more suspect.

Q: Can a company's audit firm sign off on an unfair related-party transaction?

A: Auditors check whether related-party transactions are disclosed and whether amounts are accurate. They are less equipped to determine whether prices are "fair" unless the company engages an independent valuator. So yes, an unfair transaction can pass the audit as long as it is disclosed correctly.

Q: Why does the SEC require related-party disclosure if it does not prevent fraud?

A: Disclosure is a transparency mechanism. It allows investors to see what is happening and make informed decisions. It also creates a paper trail that can be used to detect fraud later (via SEC enforcement, civil litigation, or shareholder class actions). Disclosure is not a guarantee of fairness, but it is a foundation.

Q: Should I avoid companies with related-party transactions?

A: Not necessarily. But you should assign a small "discount" to valuation to account for the governance risk. If related-party transactions are material (more than 5–10% of revenues or a material amount of expense), scrutinize them carefully and get comfortable with the business rationale and price.

Q: How is Regulation FD related to related-party transactions?

A: Regulation FD (Fair Disclosure) requires that companies disclose material information to all investors simultaneously. A related-party transaction that is material but not disclosed to the public until a footnote is filed could be a Reg FD violation. If you see evidence that insiders knew about a material related-party transaction before the public, that is a serious red flag.

Q: What if a related-party transaction is at "market rates" but still bothers me?

A: Trust your instinct. Even at market rates, a transaction might lack clear business rationale. For example, a company might pay market rates to a consulting firm (owned by the CEO) but the consulting work might be redundant with internal expertise. The price is fair, but the transaction itself is wasteful. This is a softer red flag—not fraud, but indicating weak governance.

Q: Can related-party transactions be a sign of strength?

A: Rarely, but sometimes. If a company is vertically integrating (making goods that it previously bought from third parties) by acquiring a related-party entity at a fair price, that might be a strategic move. The related-party aspect is less important than the economic logic. But always verify that the price is fair—acquiring an affiliate at a premium is a common way to siphon shareholder value.

  • Transfer pricing and tax avoidance: Related-party transactions across jurisdictions involve transfer pricing, which can be used to minimize taxes legally or illegally. This is a subset of related-party risk focused on tax.
  • Consolidation and equity-method accounting: When a company owns a related entity, it might consolidate it (fold all revenue and expenses in) or use the equity method (record only the company's share of earnings). The accounting choice can affect reported results.
  • Segment reporting and intercompany eliminations: Segment data should eliminate intra-company transactions. If segment revenues are not properly eliminated, reported revenue is inflated.
  • Corporate governance and board independence: The presence of independent board committees reviewing related-party transactions is a mitigating control. Weak governance correlates with higher related-party risk.
  • Fraud forensics and forensic accounting: Related-party transactions are a common starting point for forensic investigations. The toolkit includes benchmarking prices, tracing cash flows, and reconstructing transaction history.

Summary​

Related-party transactions are inherent conflict-of-interest situations, and they are where fraud often hides. When you see related-party transactions disclosed in a footnote, do not skip over them. Read the description carefully: What is the transaction? Who is the related party? What is the price? Is it at market rates? Was it approved by an independent committee?

If a transaction involves a large payment to an entity controlled by an insider, or a transfer of assets at unusual prices, or a loan on favorable terms, dig deeper. Cross-reference the transaction to the proxy statement and MD&A. See if third-party pricing or valuations are available. If the company cannot justify the transaction on economic merits or in terms of market rates, treat it as a governance red flag.

The presence of related-party transactions does not prove fraud, but it raises the risk and warrants extra scrutiny. Combine this red flag with others (weak board, high insider ownership, prior restatements, or aggressive accounting) to form a complete assessment of management integrity.

Related-party transactions are at least visible (disclosed in footnotes). Off-balance-sheet arrangements are arrangements that, by design, are kept off the balance sheet—often with minimal disclosure.
