Explore the principles of the cost, equity, and acquisition methods for intercorporate investments, focusing on how ownership level and influence drive financial treatment, with real-world examples and helpful diagrams to master these crucial accounting techniques.
Sometimes, when analysts first encounter intercorporate investments, they think: “Surely an investment is just an investment—how complicated can it get?” Well, as soon as ownership percentages and levels of influence enter the picture, things start getting, um, interesting.
In this section, we’ll go through three major accounting treatments for intercorporate investments:
• Cost Method
• Equity Method
• Acquisition Method
Whether an investor is passive (with little to no influence) or has total control (entirely running the investee), you’ll see how the investor’s financial statements reflect that relationship. We’ll also discuss how to identify significant influence vs. control, what happens with potential voting rights, and how to treat transitions (like moving from a small ownership stake to full control).
Let’s do a quick introduction:
Understanding these distinctions is crucial for analyzing and interpreting financial statements properly. Let’s walk through each method in more detail.
Under the cost method, the investor records the investment at its original purchase price (i.e., “cost”). Dividends received from the investee are recognized as dividend income. However, there’s no ongoing recognition of the investor’s share of the investee’s earnings. In other words, the carrying amount on the balance sheet doesn’t change unless there’s an impairment or the investor receives additional shares or capital distributions that affect the investment basis.
Cost Method is typically applied when:
Let’s say I (the investor) buy 5% of Company A’s shares for $100,000. Because I own only 5% and have no board seat or any other formal or informal influence, I’d likely use the cost method, recording an “Investment in Company A” at $100,000. Any dividends from Company A show up as dividend income on my income statement when received.
If Company A’s stock doubles or halves in market value, I don’t adjust the carrying value on my books under traditional cost method rules—unless there’s a requirement to mark to market under certain fair value or IFRS/US GAAP classification. However, if there’s a permanent impairment (for instance, Company A goes bankrupt), I’d then reduce the carrying value to comply with impairment rules.
The equity method steps things up a notch. Here, the investor has significant influence but not control, which is most commonly represented by ownership of roughly 20%–50%. However, the precise percentage is not the only factor; having board representation or other contractual rights can also confer significant influence.
Under the equity method:
In simpler terms:
Carrying Value at Period End = Initial Cost + (Investor’s Share of Investee Net Income) – (Investor’s Share of Dividends)
If the investee earns a profit, the investor’s carrying value goes up. If the investee pays out a dividend, the carrying value goes down. This method recognizes that the investor exerts enough influence to effectively share in the investee’s results.
I once worked with an organization that owned 25% of a local telecommunications startup. Because the startup’s strategy was heavily influenced by that 25% stakeholder—our folks even had a seat on the board—this was definitely an equity-method scenario, not just a passive investment. Every quarter, we’d gather the startup’s financials, calculate our share of their net income, and adjust the investment’s carrying amount accordingly.
Under both IFRS and US GAAP, if there’s evidence of impairment, we have to record an appropriate write-down. Additionally, certain fair value options exist if the standard setter’s guidelines permit or require it. But typically, the classic equity method is straightforward: track your portion of net income and dividends.
Below is a simple Mermaid diagram illustrating how losses or income flow to the investor under the equity method:

The acquisition method kicks in when an investor has control—often more than 50% of voting shares, but potentially less if certain conditions or contractual powers provide control. Under IFRS and US GAAP, “control” is broadly defined. There’s also the concept of special-purpose entities or variable interest entities (VIEs) where an investor can control the entity’s activities without traditional majority ownership.
With control comes the need to consolidate the investee’s financials with the investor’s. This means we:
When an acquisition occurs:
This goodwill remains on the consolidated balance sheet and is tested for impairment rather than amortized.
Think about it like cooking soup with various ingredients: Once you’re in total control (you have the pot, the vegetables, the water, the spices), the entire outcome—taste, aroma, color—belongs to you. If someone else has a small share of that pot, we track them as a “noncontrolling interest.” But you still present the soup in one big bowl.
Below is a simplistic look at how consolidation might stack up:
flowchart TB A["Parent Company Financials"] --> C["Consolidated Financials (Parent + Subsidiary)"] B["Subsidiary Company Financials"] --> C["Consolidated Financials (Parent + Subsidiary)"] C --> D["Noncontrolling Interest <br/>(Displayed Separately)"]
A tricky corner in these standards is potential voting rights and variable interest entities. If, for instance, you have stock warrants or convertible debt that can be exercised anytime (and that exercise would give you a majority stake), you may effectively have control right now, depending on IFRS/US GAAP guidelines.
Similarly, with a VIE, you might control the entity’s most significant activities through contractual terms (like controlling the majority of the variable returns), even if you hold a small equity interest. In that scenario, you’d consolidate the VIE.
Sometimes, an investor’s ownership changes over time. For instance, you might start with a 15% stake and then acquire enough shares to jump over the 20% mark. Here’s how it generally goes:
The logic behind these adjustments is that any previous carrying amounts may no longer reflect the economic reality once your degree of influence or control changes.
Let’s say you hold 15% of a small robotics company at a cost of $200,000, using the cost method. That stake’s fair value at the last reporting date is $220,000. Suddenly, you purchase additional 40% for $800,000, bringing total ownership to 55%. Now you have control, so you move to the acquisition method.
Steps:
The result is a single consolidated statement, with any noncontrolling interest recognized if you don’t own 100%.
To visualize the ownership thresholds and the associated accounting methods:
flowchart LR A["<20% <br/>No Influence <br/>(Cost Method)"] --> B["20%-50% <br/>Significant Influence <br/>(Equity Method)"] B --> C[">50% <br/>Control <br/>(Acquisition Method)"]
Of course, these thresholds are rules of thumb, and actual influence or control can arise at different percentages based on contractual or legal rights.
• Pitfall: Mixing Dividends and Earnings Under the Equity Method
– Always remember: under equity method, dividends reduce the investment account.
• Pitfall: Overlooking VIE Arrangements
– Even if your equity stake is small, you might have control contractually. Carefully check if your “small stake” is actually a big control situation.
• Pitfall: Incorrect Purchase Price Allocation in Consolidations
– Precisely measure the fair value of intangible assets, liabilities, and contingent liabilities. Overlooking intangible brand value, for instance, can lead to a misstatement of goodwill.
• Best Practice: Keep an Eye on Potential Voting Rights
– Options, warrants, or convertibles can instantly tilt the scale from “no control” to “full control” if they’re exercisable and in the money.
• Best Practice: Document Transition Steps Thoroughly
– Whenever changes in ownership occur, note the remeasurement and the fair-value thresholds in your workpapers or schedule to ensure transparency and compliance.
Understanding cost, equity, and acquisition methods is pivotal for accurate financial statement analysis. It’s not just about memorizing thresholds—it’s about recognizing the substance of the relationship between an investor and an investee. Always follow these steps:
This knowledge will help you read through corporate structures, interpret consolidated statements, and evaluate whether a holding should be considered just a line item or part of a bigger, consolidated picture.
