Under GAAP, related party transactions are governed primarily by ASC Topic 850, which requires the reporting entity to identify parties that control or significantly influence it, record most transactions with those parties at the amount actually exchanged, and disclose the relationship and the dealings in the footnotes even when no money changed hands. Public companies apply SEC rules on top of ASC 850, and auditors apply heightened scrutiny under PCAOB standards. The reason the rules exist is that related parties do not bargain at arm’s length, so the stated price may not reflect what two strangers would have agreed to, and the financial statements have to alert users to that fact.
Who Counts as a Related Party
ASC 850 defines related parties broadly, by asking whether one party can control or significantly influence the other’s financial and operating decisions. The named categories are:
- Affiliates, meaning entities that share a common parent, such as two subsidiaries of the same corporation.
- Equity method investees, where the reporting entity holds enough ownership to use the equity method.
- Employee benefit trusts, such as pension plans and profit-sharing trusts managed by the entity’s own leadership.
- Principal owners and their immediate families.
- Management and their immediate families, including officers, directors, and others who direct the entity’s activities.
“Immediate family” is defined by influence, not by a fixed list of relatives. It reaches any family member who might control or influence a principal owner or member of management, or be controlled or influenced by them, because of the family relationship. That judgment falls to management and can extend well beyond spouses and children depending on the facts.
The categories are not exhaustive. Management has to apply judgment about whether a relationship involves enough control or influence to qualify, even if it does not fit neatly into a named group. Complex ownership structures, joint ventures, and de facto agency relationships where one party acts on behalf of another without a formal agreement are where that judgment gets tested.
What Counts as a Related Party Transaction
A related party transaction is any transfer of resources, services, or obligations between the reporting entity and a related party. Sales, purchases, leases, loans, and management service arrangements are the obvious examples. The scope is wider than most preparers first assume.
A transaction qualifies even when no money changes hands. An interest-free loan, administrative services provided at no cost, or office space used without a lease payment all fall within ASC 850. The trigger is the relationship and the transfer of economic value, not whether an invoice was issued.1Deloitte Accounting Research Tool (DART). 5.3 Related-Party Transactions Zero-price transactions are where the most significant measurement and disclosure issues arise, and they are the easiest to miss.
One scope carve-out matters in practice. Compensation arrangements, expense allowances, and similar items in the ordinary course of business sit outside ASC 850’s detailed disclosure rules, even though management is a related party. A private company whose only employees are its owners does not need to lay out granular detail about ordinary salary arrangements in the related party footnote. Unusual compensation, or arrangements that go beyond routine pay, still get full disclosure.
Measuring Related Party Transactions
The measurement problem is that the agreed price may have nothing to do with fair value. Two subsidiaries of the same parent can set any price they want, and there is no market to push back. GAAP handles this with a general rule and specific guidance for a handful of common transaction types.
The General Rule
Related party transactions are generally recorded at the amount actually exchanged between the parties. If a parent sells inventory to its subsidiary for $500,000, the subsidiary records a $500,000 purchase, even if the fair value is $750,000. The footnotes then carry the burden of alerting readers to the relationship and the possibility that the price was not arm’s length.
The measurement approach shifts when the transaction is effectively a capital contribution, a dividend, or a non-monetary exchange, and for the specific arrangements below.
Common Control Transfers
When assets or entire businesses move between entities under common control, the receiving entity records what it gets at the historical carrying amount used by the parent of the group. This predecessor-basis accounting prevents the artificial recognition of gains or losses within a controlled group. Any difference between the consideration paid and the net carrying amount of what was received goes directly to equity, not to the income statement.
For asset transfers, the receiving entity picks up the assets at carrying value on a going-forward basis. For transfers of entire businesses, the receiving entity typically restates its prior-period financial statements as if the combination had always existed. The transferring entity treats the transaction as a disposal and records any gap between proceeds and book value as an equity adjustment.
Below-Market and Interest-Free Loans
GAAP treatment of below-market loans depends on the relationship. ASC 835-30, which governs imputed interest on notes and receivables, explicitly excludes transactions between a parent and its subsidiaries and between subsidiaries of a common parent. For loans within a consolidated group, the general GAAP imputation rules do not apply, though the related party disclosure requirements still do.
For loans between other types of related parties where ASC 835-30 does apply, interest must be imputed at a market-based rate. The difference between the stated rate and the imputed rate is typically treated as a capital contribution or a distribution, depending on the direction of the transfer.
Tax law runs on a separate track. Section 7872 of the Internal Revenue Code imputes forgone interest on below-market loans based on the Applicable Federal Rate, and that imputation happens regardless of the GAAP result. Preparers dealing with intercompany loans should expect the book and tax numbers to diverge.
Leases Between Related Parties
Under ASC 842, leases between related parties follow the same classification and measurement rules as any other lease, with one twist: classification rests on the legally enforceable terms and conditions of the arrangement, not just the written contract. When related parties share a controlling owner and can modify a lease at will, the enforceable terms can differ from what is written down.
ASU 2023-01 gives private companies and not-for-profit entities a practical expedient. They can use the written terms of a common-control arrangement to determine whether a lease exists and how to classify it. If nothing is written down, the shortcut is unavailable and the entity has to apply ASC 842 to whatever terms are legally enforceable.
Footnote Disclosures Required by ASC 850
Measurement alone cannot convey the risk that a related party relationship creates. The footnotes carry that work.
Core Disclosure Elements
For each material related party transaction, the financial statement footnotes have to include:
- The nature of the relationship, identified explicitly as parent-subsidiary, entity-key management personnel, common ownership, or whatever the actual type is.
- A description of the transaction with enough detail that a reader can understand its effect on the financial statements, including transactions where no amounts or only nominal amounts were assigned.
- The dollar amounts of transactions for each period presented in the income statement, plus disclosure of any change in how the terms were established compared to the prior period.
- Settlement terms, meaning how the transaction was settled or will be settled, whether through cash, non-monetary assets, or the creation or forgiveness of debt.
- Outstanding balances due from or to related parties as of each balance sheet date, shown separately from balances owed by or to unrelated parties.
Common Control With No Transactions
If the reporting entity and another entity are under common ownership or management control, the nature of that control relationship has to be disclosed even when no transactions occurred during the period. The reasoning is that common control itself can distort results, because a parent could direct business away from one subsidiary to benefit another, and financial statement users need to know that possibility exists. The disclosure is triggered by the relationship alone.1Deloitte Accounting Research Tool (DART). 5.3 Related-Party Transactions
Careful With the Arm’s-Length Assertion
Companies sometimes want to state in the footnotes that a related party transaction was conducted on terms equivalent to arm’s length. GAAP allows the claim only when the company can substantiate it, typically through independent market studies or appraisals showing the terms mirror what an unrelated third party would have accepted.1Deloitte Accounting Research Tool (DART). 5.3 Related-Party Transactions Substantiation is expensive and difficult to obtain, and most companies avoid the assertion rather than risk making a claim they cannot defend.
Guarantees Between Related Parties
Intercompany guarantees are common, and the accounting is more nuanced than many preparers assume. Under ASC 460, a guarantor normally has to recognize a liability at inception for the fair value of the guarantee obligation. Guarantees between parents and subsidiaries, and between entities under common control, are explicitly exempt from both the recognition and measurement provisions of ASC 460.2Financial Accounting Standards Board (FASB). Summary of Interpretation No. 45
The exemption covers a parent’s guarantee of its subsidiary’s debt to a third party, a subsidiary’s guarantee of its parent’s debt, and guarantees between sister subsidiaries. No fair value liability is booked for any of these arrangements in the consolidated financial statements.
The exemption from recognition does not remove the guarantee from the footnotes. Related party guarantees remain subject to the disclosure requirements of both ASC 460 and ASC 850. Stand-alone financial statements of a subsidiary whose parent has guaranteed its debt still have to disclose the guarantee, even though no liability is recognized for it.
Consolidated vs. Separate Financial Statements
A common point of confusion. Transactions between a parent and its wholly-owned subsidiary are eliminated in consolidation for external reporting. The sale, the receivable, the payable, and any unrealized profit all disappear from the consolidated statements. That elimination does not excuse the entities from ASC 850’s disclosure requirements in their separate financial statements.
If a subsidiary issues stand-alone financial statements to lenders, regulators, or minority investors, those statements must carry the full related party footnote, including the nature of the relationship, transaction amounts, settlement terms, and outstanding balances. Consolidation makes the transactions invisible in the group financials; separate-entity disclosure makes them visible again where they matter to users.
Extra Rules for Public Companies
Public companies face additional related party reporting on top of ASC 850, meant to put the information where investors will actually see it.
Regulation S-X Presentation
Rule 4-08(k) of Regulation S-X requires related party transaction amounts to appear on the face of the balance sheet, statement of comprehensive income, or statement of cash flows, not only in the notes. When separate financial statements are presented for investees or subsidiaries, any intercompany profits or losses from related party transactions and their effects also have to be disclosed.3eCFR. 17 CFR 210.4-08 – General Notes to Financial Statements
Regulation S-K Item 404
Item 404 requires disclosure in proxy statements and annual reports of any transaction since the beginning of the last fiscal year, or any currently proposed transaction, in which the registrant was or will be a participant, the amount involved exceeds $120,000, and any related person had or will have a direct or indirect material interest. Smaller reporting companies use the lower of $120,000 or one percent of the average of their total assets at year-end for the last two completed fiscal years.4eCFR. 17 CFR 229.404 – Transactions With Related Persons, Promoters and Certain Control Persons
Form 8-K
If a public company enters into a material definitive agreement outside the ordinary course of business, a Form 8-K has to be filed describing the agreement, including any material relationship between the registrant or its affiliates and the other parties. Termination of such an agreement triggers the same filing. A significant new related party contract can create an immediate disclosure obligation, not just a year-end footnote.
What Auditors Will Do With Your Related Party Population
Related party transactions get more audit attention than nearly any other area of the financial statements, because they are a known vector for fraud and earnings manipulation. Under PCAOB Auditing Standard 2410, auditors of public companies must inquire of management about the names of all related parties, changes from the prior period, the nature and ownership of each relationship, and the terms and business purposes of transactions entered into or terminated during the period. They also have to ask about transactions that were not authorized under company policies or where exceptions were granted.5PCAOB Public Company Accounting Oversight Board. AS 2410 – Related Parties
The inquiries do not stop with management. Auditors have to question other people inside the company who are likely to have knowledge of related party relationships, and they discuss the topic with the audit committee or its chair, including whether any committee member has concerns about specific relationships or transactions.
For any related party transaction that requires disclosure or that the auditor flags as a significant risk, the auditor reads the underlying documentation and evaluates whether the terms are consistent with management’s explanations. They verify authorization and approval under company policies and check whether exceptions were granted and properly documented.5PCAOB Public Company Accounting Oversight Board. AS 2410 – Related Parties Auditors also search for undisclosed related parties by reviewing tax filings, corporate life insurance policies, contracts, organizational charts, and the company’s website. Contracts for below-market goods or services, bill-and-hold arrangements, uncollateralized loans, and sale-and-repurchase patterns are red flags they specifically look for.
