Intercorporate Investments: Fair Value, Equity Method and Consolidation

By Ryan O'Connell, CFA, FRM Published November 5, 2026

When one company buys shares in another, the accounting depends on the relationship those shares create. A small portfolio holding, an influential minority stake, and a controlled subsidiary can produce very different financial statements even when each investment begins with a cash purchase.

Intercorporate investments are investments by one company in another entity. This guide focuses on U.S. GAAP for an ordinary corporate investor holding common or in-substance common equity. It explains fair-value accounting, the equity method, and consolidation, then follows one hypothetical equity-method investment from purchase through year-end.

Three Accounting Models for Intercorporate Investments

For ordinary corporate equity investments, the starting framework is ASC 810 for consolidation, ASC 323 for the equity method, and ASC 321 for other equity securities. These models answer different questions: does the investor control the business, influence its policies, or simply hold an investment? Specialized entities and eligible accounting elections can change this framework.

The middle row is often called a one-line investment: the investor recognizes its interest through an investment balance and equity-method income rather than adding its percentage of every revenue and expense line. Consolidation instead reports the controlled business within the group. FASB’s issued ASC 321 amendments expressly exclude investments accounted for under consolidation or the equity method.

This equity framework should not be applied indiscriminately to corporate bonds. Debt has separate classification and credit-loss rules, covered in investment securities classification.

Ownership Thresholds: Influence and Control

Significant influence is an ability to participate

Significant influence concerns the ability to participate in an investee’s operating and financial policy decisions. Evidence includes board representation, policy participation, material transactions between the companies, interchange of managers, technological dependency, and the investor’s ownership relative to other shareholders. A board seat matters, but no isolated indicator automatically settles every case.

For voting stock of a corporation, ownership of 20% or more creates a rebuttable presumption of significant influence; ownership below 20% creates a rebuttable presumption that influence is absent. Contrary evidence can overcome either presumption. A smaller stake with meaningful policy rights may qualify, while restrictions on a larger investor’s rights can support a different conclusion. The current wording and indicators are reproduced in issuer correspondence quoting ASC 323-10-15-6 through 15-8; that correspondence is an issuer’s analysis, not an SEC endorsement.

As a real application, Berkshire Hathaway’s 2025 Form 10-K, Notes 1 and 4–5, explains that passivity commitments restrict its significant influence over American Express, whose shares it reports at fair value. The filing identifies Kraft Heinz and Occidental common stock as equity-method investments. The relevant lesson is to examine the rights and instrument involved, rather than classify every strategic holding identically.

Control is a separate, stronger relationship

For an ordinary voting-interest entity, majority voting ownership generally indicates a controlling financial interest. However, substantive participating rights held by other owners may overcome that conclusion; merely protective rights generally do not. A veto over an exceptional action protecting a lender or minority owner differs from substantive participation in significant ordinary business decisions. FASB’s consolidation guidance amendments explain these distinctions.

Voting percentages also do not resolve every variable interest entity, or VIE. Under the VIE model, the primary beneficiary needs both power to direct the activities that most significantly affect economic performance and an obligation to absorb losses or a right to receive benefits that could potentially be significant. Economic exposure alone is insufficient, as is power without the required economics. See ASC 810-10-25-38A as reproduced in ASU 2016-17.

A special-purpose vehicle is therefore neither automatically consolidated nor automatically outside the group. Read its contracts, decision rights, financing, and loss-sharing arrangements. Our project company and SPV guide explains the business structure; the accounting conclusion requires the separate control analysis.

ASC 321: Equity Investments Without Significant Influence

For qualifying equity securities outside consolidation and the equity method, ASC 321 generally requires subsequent measurement at fair value, with changes recognized in net income. An ordinary dividend also generally enters earnings. A quoted price increase can therefore change income even when the investor sells no shares.

The dividend does not reduce the ending fair value in this example; that amount is measured independently. The ending investment plus cash is $67,800, reconciling to the $60,000 starting cost plus $7,800 of income.

A security without a readily determinable fair value may qualify for an elected measurement alternative: cost less impairment, adjusted for observable price changes in orderly transactions for identical or similar investments of the same issuer. Eligibility conditions apply, including the exclusion for securities eligible for the net-asset-value practical expedient. “Private shares stay at cost forever” is therefore an unreliable shortcut. This alternative also differs from an ASC 825 fair-value-option election.

How the Equity Method Works

Under the equity method, begin with investment cost. Then recognize the investor’s share of the investee’s post-acquisition earnings or losses, with required adjustments. Eligible investee other comprehensive income also changes the investment, but enters the investor’s OCI rather than net income. Dividends generally reduce the investment because the investor has already recognized its share of the underlying earnings.

For a simple holding with unchanged ownership, the core bridge is:

This model tracks the investor’s accounting interest in changes in net assets. It does not continuously mark the stake to its stock-market price. Berkshire’s investment policies and Honeywell’s 2026 equity-method accounting disclosure illustrate these mechanics. For the distinction between earnings and OCI, see the income statement and comprehensive income.

Equity-Method Example: Purchase Through Year-End

The following companies and amounts are entirely hypothetical. On January 1, Northstar Corp. buys 30% of Harbor Systems’ voting common stock for $360,000 cash. Northstar has significant influence but no control under ASC 810, and has not elected the fair-value option. Use the ordinary public corporate-investor treatment, with no private-company goodwill alternative.

Harbor’s opening book net assets are $1,000,000. Northstar’s acquisition analysis assigns $30,000 of its own purchase-basis excess to equipment with five remaining years of useful life, straight-line depreciation, and no residual value. The residual excess is equity-method goodwill. Ignore allocation-related deferred taxes and investor-level taxes to isolate the accounting mechanics.

1. Explain the purchase-basis difference

Northstar’s share of Harbor’s opening book equity is 30% × $1,000,000 = $300,000. The purchase price exceeds that amount by $360,000 − $300,000 = $60,000. Allocate that excess as follows; the equipment amount shown is already Northstar’s 30% share, so do not multiply it by 30% again.

Northstar records one investment asset, not separate equipment and goodwill assets for this holding. The allocation is a supporting schedule used to adjust subsequent equity income. Finite-life basis differences require amortization or depreciation as applicable; equity-method goodwill follows different treatment. Honeywell’s policy and ConnectM’s 2026 equity-method note describe this distinction. Related background appears in goodwill and intangible assets and depreciation methods.

2. Recognize income, OCI, and the dividend

During the full year, Harbor reports $200,000 of net income, a $20,000 eligible OCI gain, and $80,000 of dividends declared and paid. Harbor’s income already includes its book depreciation and its own taxes. Assume unchanged 30% ownership and pro-rata allocations, with no impairment, intercompany gains, contributions, or other basis differences.

Northstar’s unadjusted share of income is 30% × $200,000 = $60,000. Subtract the $6,000 equipment-basis depreciation to obtain $54,000 of equity-method income. Its share of OCI is 30% × $20,000 = $6,000, and its dividend cash is 30% × $80,000 = $24,000.

The entries below show the two earnings steps separately so the basis adjustment remains visible. The dividend is declared and paid in the same period; no separate dividend-receivable timing entry is needed for this illustration. Debit and credit mechanics are explained in double-entry accounting.

The $60,000 credit and $6,000 debit to equity in earnings leave $54,000 of net income. The $6,000 OCI credit enters comprehensive income separately and ultimately accumulated OCI in equity. The $24,000 dividend exchanges part of the investment balance for cash; adding it to equity-method income would count a distribution as a second earnings event.

3. Reconcile the ending carrying value two ways

First, roll Northstar’s investment forward from its $360,000 cost using those entries. The table separates earnings, OCI, and cash distributions so each change has one place.

Second, reconcile to Harbor’s ending equity. Harbor ends with $1,000,000 + $200,000 + $20,000 − $80,000 = $1,140,000 of book equity. Northstar’s 30% share is $342,000. The equipment basis difference has $30,000 − $6,000 = $24,000 remaining, and goodwill remains $30,000.

The two approaches agree. Northstar’s investment increased $36,000 and it received $24,000 cash, totaling $60,000 of comprehensive gain: $54,000 net income plus $6,000 OCI. None of these amounts means the investment could be sold for exactly $396,000.

Basis Differences, Impairment, and Losses

The worked example isolates the main mechanics. Real equity-method accounting also requires attention to the following adjustments:

• Purchase-basis differences: differences assigned to inventory, depreciable assets, or other finite-life items affect income when the related items are sold, consumed, or amortized. The investee’s reported income alone is insufficient.
• Impairment: assess declines in value under the equity-method impairment guidance. An other-than-temporary decline requires a write-down; a lower market quotation does not automatically create the same recurring fair-value entry as ASC 321. Equity-method goodwill is included in the investment’s impairment assessment rather than tested as a separately recognized goodwill asset.
• Intercompany transactions: unrealized profits on transactions between investor and investee can require elimination to the extent applicable to the investor’s interest. A transfer loss may provide impairment evidence and cannot always be deferred mechanically. Timing and the underlying asset matter.
• Changed rights or ownership: reassess the model when acquisitions, disposals, contracts, or governance arrangements change influence or control. ASU 2016-07 addresses entering the equity method when an investment qualifies; historical ownership alone does not fix the method forever.

Losses do not have an unconditional zero-balance cap

An investor ordinarily stops applying equity-method losses after the relevant investment exposure has been reduced to zero, unless further loss recognition is required. Examine other at-risk interests, net advances, guarantees, and support commitments before concluding that a common-share balance of zero ends the analysis. FASB’s ASC 323 amendments, Berkshire’s policies, and COPT’s 2026 equity-method disclosure illustrate these qualifications.

Consolidation and Noncontrolling Interest

When control requires consolidation, the group generally includes 100% of the subsidiary’s assets, liabilities, revenue, and expenses, subject to consolidation adjustments. Amounts belonging to outside owners are then identified through noncontrolling interest, or NCI. This is different from multiplying each subsidiary line by the parent’s ownership percentage.

Consider a separate hypothetical parent owning 80% of a controlled subsidiary’s plain common equity; the other 20% is ordinary nonredeemable NCI. The subsidiary has $1,000,000 of external annual revenue and $800,000 of expenses, including relevant taxes. Assume no intercompany transactions, acquisition-basis differences, preferred claims, or other allocation adjustments. The table isolates the subsidiary’s contribution to the consolidated statements.

Consolidated revenue includes the entire $1,000,000; the $40,000 NCI attribution does not reduce revenue. Ordinary NCI is presented in equity separately from equity attributable to the parent. Redeemable interests and unusual security rights can require different presentation. FASB’s historical Statement 160 explains the principles now codified in ASC 810.

Full consolidation also removes the parent’s investment against subsidiary equity and eliminates relevant intragroup balances and transactions. Those worksheet mechanics are beyond this investor-classification guide. Consolidated debt can include obligations of a legally separate subsidiary, so accounting consolidation should not be mistaken for a legal guarantee by the parent.

For a complete parent-subsidiary worksheet, see consolidated financial statements and elimination entries, including the separate presentation of noncontrolling interests.

Joint Ventures and Important Scope Exceptions

Joint ownership describes an arrangement; it does not supply a universal accounting answer. In a corporate joint venture without a controlling venturer, an investor commonly applies the equity method. First inspect the governance agreement and ASC 810 requirements, including any applicable VIE analysis. A 50:50 split by itself does not establish that neither party controls the entity.

Keep the investor’s books separate from the venture’s own books. ASU 2023-05 on joint venture formations addresses the venture’s recognition and measurement at formation; it does not replace the venturer’s equity-method accounting or redefine a joint venture.

Also check these qualifications before using the simple corporate thresholds:

• Legal form and security terms: partnership interests and certain LLC structures have equity-method scope rules that differ from the ordinary corporate voting-stock framework. Preferred shares, warrants, and other instruments are not automatically common or in-substance common stock.
• Specialized entities: investment companies, broker-dealers, and certain other entities follow specialized guidance. Their fair-value accounting cannot be generalized to an ordinary corporate parent.
• Fair-value option: eligible equity-method investments may qualify for an ASC 825 election at specified election dates. Eligibility and election-unit rules matter. The option does not let an ordinary parent bypass required consolidation. FASB’s historical Statement 159 provides the background now codified in ASC 825.
• Private-company alternatives: qualifying private entities can elect specified alternatives, including a conditional common-control VIE alternative. ASU 2018-17 retains other consolidation requirements and disclosures; it is not a blanket private-company exemption.

Fair Value vs. Equity Method vs. Consolidation for Analysis

The accounting model changes where economic activity appears. Read the investment and consolidation notes before comparing companies’ margins, leverage, or returns.

For example, comparing enterprise value to EBITDA requires consistency between the businesses included in the valuation numerator and earnings denominator. A nonconsolidated investment value paired with earnings that exclude its operations may need an explicit adjustment. Likewise, return on assets can reflect a one-line equity-method asset for one company and a subsidiary’s full asset base for another. Neither model universally produces a better ratio.

Reconcile earnings with distributions and cash movements rather than treating equity-method income as cash received. The statement of cash flows supplies a separate perspective, while the three financial statements explain how income, assets, and cash connect.

Common Mistakes in Intercorporate Investment Accounting

• Using 20% and 50% as automatic switches. Start with scope, actual rights, and the appropriate control model; use the corporate influence presumptions within that analysis.
• Counting equity-method dividends as additional earnings. They generally reduce an investment already increased for the investor’s earnings share.
• Ignoring acquisition-basis differences. A percentage of reported profit may overstate equity income when extra depreciation or amortization is required.
• Calling carrying value fair value. The equity-method rollforward is an accounting basis, not a sale-price quotation.
• Recognizing only 80% of a controlled subsidiary’s revenue. Full consolidation and NCI attribution are separate steps.
• Stopping loss analysis at zero common-share carrying value. Other at-risk interests and support obligations may require further recognition.

Limitations and Practical Review Questions

Before preparing entries, document which model applies and why; identify the reporting period, purchase allocation, income and OCI information, distributions, and exposure to losses. Then reconcile the investment schedule to the financial statements and reassess after material changes. This article addresses U.S. financial reporting, not tax consolidation, dividends-received deductions, or an IFRS classification conclusion.
