You need to revalue an investment in a subsidiary when specific accounting rules require it. According to ASC guidance on investments, subsidiaries fall under different accounting methods depending on whether you control them, significantly influence them, or have a passive investment. The choice of accounting method directly affects whether you must adjust the investment’s value on your balance sheet. Around 35% of companies with subsidiaries experience valuation issues during annual audits because they apply the wrong accounting method or fail to test for impairment when conditions change.

Understanding Subsidiary Investments and Their Accounting Rules
A subsidiary is a company that another company controls. Control typically means owning more than 50% of the voting shares, though this can happen with less ownership in certain situations. The parent company must reflect this investment on its separate financial statements, and the accounting method depends on the type of control or influence the parent has.
When you buy a subsidiary, you record the investment at cost. That cost becomes your starting point on the balance sheet. But this starting point does not stay frozen forever—it changes based on the accounting method required by either U.S. GAAP or IFRS standards, depending on which framework the company uses.
The key concept is that different ownership levels trigger different accounting treatments. Federal accounting standards under the Financial Accounting Standards Board require companies to evaluate their relationships with investees and apply the appropriate method. The parent company must also test the investment for impairment—meaning checking whether the investment’s value has dropped and whether you need to write it down.
The Three Main Accounting Methods for Subsidiaries
The Cost Method: No Revaluation Until Impairment Strikes
Under the cost method, you record the subsidiary investment at its original purchase price and leave it there unless impairment occurs. This method applies when you own a subsidiary but are not required to consolidate or use equity accounting. You recognize dividend income when the subsidiary pays dividends, not based on the subsidiary’s profits.
The cost method feels simple on the surface, but it creates a critical problem: your balance sheet does not reflect changes in the subsidiary’s value. If the subsidiary’s business deteriorates, your investment remains on the books at its original cost until you test for and identify impairment. This disconnection between economic reality and your balance sheet can mislead investors and creditors about the true value of your assets.
The Equity Method: Continuous Revaluation Based on Earnings
The equity method requires you to adjust the investment’s carrying value based on the subsidiary’s net income or loss. When the subsidiary earns profit, you increase the investment value; when it loses money, you decrease it. You also reduce the investment by dividend distributions.
This method applies when you have significant influence over the investee—typically owning 20-50% of voting shares, though this is a rebuttable presumption. The equity method forces continuous revaluation, which means your balance sheet more closely tracks economic reality. However, this constant adjustment also means your profit and loss statement fluctuates based on the subsidiary’s performance, which some investors find volatile or hard to predict.
The Fair Value Method: Market-Based Revaluation
Fair value accounting requires you to revalue the investment to its current market price at each reporting date. Under ASC 321 equity investments, you can elect fair value for equity investments without control or significant influence. Changes in fair value flow through either net income or other comprehensive income, depending on your election.
Fair value updates your balance sheet most frequently and most accurately reflects current economics. But it also creates accounting volatility because value swings directly impact your financial statements. For publicly traded subsidiary investments, finding current market prices is straightforward; for private subsidiaries, fair value becomes an estimate based on comparable companies, valuation models, or transaction data.
When Revaluation Becomes Mandatory: The Impairment Test
You must perform an impairment test whenever triggering events suggest your investment’s value has dropped. These events include declining subsidiary revenues, loss of major customers, technology obsolescence, regulatory changes, or significant market downturns. Impairment testing applies to investments under the cost method and also applies to equity method investments as a secondary check.
Under ASC 360 property and equipment, you compare the investment’s carrying value to the subsidiary’s undiscounted cash flows. If undiscounted cash flows fall below the carrying value, you measure impairment by comparing the investment’s fair value to its carrying value. The difference becomes an impairment loss that flows through your income statement.
The impairment process forces revaluation even under the cost method, which normally avoids frequent updates. This creates a floor below which your investment value cannot fall on the balance sheet without triggering a write-down. Failing to perform impairment testing when events indicate impairment is a serious audit finding and can lead to overstated assets on your financial statements.
Scenarios: When and Why Revaluation Happens in Real Situations
Scenario 1: The Subsidiary Loses Its Largest Customer
| Trigger Event | Required Revaluation |
|---|---|
| Subsidiary loses 60% of revenue from its biggest client | Perform impairment test immediately; likely write down investment to fair value |
| Investment recorded at cost of $5 million; fair value now $2.5 million | Recognize $2.5 million impairment loss on income statement |
| Carrying value on balance sheet reduces from $5M to $2.5M | Future earnings from subsidiary are compared to new baseline when testing for reversal |
This scenario reflects a common triggering event in manufacturing and distribution businesses. When a subsidiary depends heavily on one or two major customers and loses one, the business value collapses. The parent company must stop ignoring this reality and write the investment down through impairment testing. Auditors specifically look for customer concentration issues during their procedures.
Scenario 2: Ownership Structure Shifts From 40% to 65% Control
| Change in Ownership | Accounting Method Shift |
|---|---|
| Parent increases ownership from 40% (significant influence) to 65% (control) | Switch from equity method to consolidation; remeasure investment at fair value on transition date |
| Investment balance under equity method was $3 million | Any difference between fair value and carrying value triggers a one-time gain or loss |
| Parent now controls subsidiary; consolidated statements replace equity accounting | Parent’s separate statements show investment at fair value with consolidation adjustments |
This scenario creates a pivotal accounting moment. Moving from significant influence to control means the parent company must shift from equity method accounting to consolidation, which represents a fundamental change in how the investment appears. The transition often triggers a gain or loss because the investment’s fair value rarely equals its equity method carrying value. After transition, the parent company’s separate statements still show the investment, but now at fair value with consolidation in the consolidated statements.
Scenario 3: Fair Value Election and Market Volatility
| Market Condition | Fair Value Accounting Impact |
|---|---|
| Subsidiary’s fair value increases 20% due to strong market performance | Unrealized gain of $2M flows to comprehensive income or net income (per election) |
| Subsidiary’s fair value decreases 15% in next period due to sector downturn | Unrealized loss of $1.5M flows to comprehensive income or net income |
| Three-year cycle of gains and losses creates volatility in parent’s reported earnings | Investors see fluctuation unrelated to parent’s core operations |
Companies that elect fair value for equity investments must accept this volatility as a trade-off for balance sheet accuracy. The subsidiary’s value swings create noise in the parent’s financial statements even when the parent company’s operations remain stable. This volatility can confuse investors who do not understand that some earnings swings reflect investment revaluation rather than operational performance.
The Mechanics of Measuring Fair Value When Revaluation Happens
Fair value means the price at which an asset would exchange between a willing buyer and willing seller in an orderly transaction. For subsidiaries that trade on public markets, fair value is their current stock price multiplied by the parent’s ownership percentage. For private subsidiaries, measuring fair value requires judgment and multiple approaches.
You can estimate private subsidiary fair value using the income approach (discounting expected cash flows), the market approach (comparing to comparable company multiples), or the asset approach (valuing underlying assets). The FASB’s fair value measurement guidance requires companies to use observable market inputs when available and resort to unobservable inputs (management estimates) only when market data is unavailable. Professional appraisers often assist with these valuations for material investments.
The hierarchy of inputs matters tremendously for audit purposes. Level 1 inputs (quoted prices in active markets) are most reliable; Level 2 inputs (observable data from comparable transactions) are moderately reliable; Level 3 inputs (company estimates) are least reliable but sometimes necessary. When you use Level 3 inputs, auditors scrutinize your assumptions closely and may require sensitivity analysis showing how valuation changes if your assumptions shift by 10-20%.
Specific Rules When Ownership Percentage Changes
When your ownership percentage of a subsidiary changes, the accounting rules depend on whether you maintain control before and after the change. If you own 60% and sell down to 40%, you lose control and must stop consolidating. At that moment, you remeasure the remaining 40% investment at fair value and recognize any gain or loss through the income statement or other comprehensive income.
If you own 40% and buy additional shares to reach 75%, you gain control and must start consolidating. You remeasure the original 40% investment to fair value as if you had just acquired it that day. Any difference between the old carrying value and new fair value creates a one-time gain or loss that flows through the income statement.
Partial dispositions (selling some but not all of your subsidiary shares while retaining control) require proportional remeasurement only for the shares sold. You account for the sale itself at fair value and recognize a gain or loss on the disposed portion. The retained investment continues under equity method or consolidation rules depending on your new ownership percentage and continued control.
Impairment Testing: The Process That Forces Revaluation
Impairment testing has two steps: first, you determine whether impairment indicators exist; second, if they do, you calculate the impairment loss. Indicators include declining subsidiary revenues, loss of key customers, technological obsolescence, unfavorable regulatory changes, increased competition, or significant economic downturns. The presence of one or more indicators does not automatically mean impairment exists—it triggers the need to perform the test.
In step one of impairment testing, you estimate the subsidiary’s undiscounted future cash flows over its useful life. If undiscounted cash flows exceed the investment’s carrying value, no impairment exists and you stop. If undiscounted cash flows fall below the carrying value, you proceed to step two. Many companies incorrectly skip this step or underestimate the subsidiary’s future cash generation capacity, leading to undetected impairment.
In step two, you measure fair value using the methods described earlier (income approach, market approach, or asset approach). The impairment loss equals the carrying value minus fair value. You record this loss through the income statement, which immediately impacts profitability. For equity method investments, you reduce the investment account itself; for cost method investments, you may record an impairment reserve or directly reduce the investment, depending on company policy.
Consolidation vs. Parent-Only Financial Statements: Different Revaluation Rules
Parent companies that control subsidiaries must issue two sets of financial statements: consolidated statements (combining parent and subsidiary) and parent-only or separate statements (showing the parent’s investment in the subsidiary). These statements require different accounting methods for the same subsidiary investment. In consolidated statements, the subsidiary investment never appears—it gets eliminated and replaced by the subsidiary’s individual assets and liabilities.
Consolidation is the only option for investments where control exists. In parent-only statements, the investment account remains and reflects either cost, equity, or fair value depending on the accounting method elected. For publicly traded parent companies, the SEC requires consolidated statements as the primary presentation, with parent-only statements presented only if material.
For private companies or holding companies, parent-only statements often matter greatly because creditors and lenders want to see the parent’s separate cash position and assets available to pay debt. Different revaluation rules apply between the two sets, which can create confusion if readers do not understand that these are two different perspectives of the same investment. This dual presentation requirement creates complexity because the same subsidiary shows different investment values in each set of statements.
Cost Method Under ASC 321: When You Don’t Have to Revalue
Under ASC 321 equity securities, you can maintain cost basis for subsidiaries even after acquisition without automatically adjusting for the subsidiary’s subsequent earnings. Cost basis companies typically choose this method because they either have passive ownership despite controlling shares, or because they report under cost method accounting as a matter of company policy. Cost method revaluation happens only through impairment testing when triggering events occur.
This method can significantly understate investment values if the subsidiary grows substantially or earns profits year after year. Some companies prefer cost method precisely because it creates stable, predictable balance sheet values without earnings volatility—a preference especially common among utility companies and long-term holding companies. You cannot use cost method if you have significant influence over the investee (which triggers equity method) or if you have elected fair value (which triggers revaluation each period).
You also cannot use cost method under IFRS investment standards, which requires either consolidation or the equity method for subsidiaries and joint ventures, with fair value available only in limited circumstances. This difference between U.S. GAAP and IFRS creates challenges for multinational companies that must prepare financial statements under both frameworks. Understanding which framework applies to your reporting obligation is critical for selecting the correct accounting method.
Equity Method Mechanics: Continuous Revaluation Through Earnings
Under the equity method, your investment account increases by your proportionate share of the subsidiary’s net income and decreases by your proportionate share of losses and dividends. This method creates automatic revaluation every period based on the subsidiary’s performance. If the subsidiary earns $1 million profit and you own 30%, your investment increases by $300,000.
Equity method complications arise when the subsidiary’s accounting methods differ from yours or when intercompany transactions exist. You must eliminate intercompany profits, adjust for purchase accounting differences, and align subsidiary accounting policies to parent policies. These adjustments happen through the equity method income calculation, which means they flow through your income statement as part of equity method earnings.
The equity method investment account represents your net book value in the subsidiary (assets minus liabilities) times your ownership percentage, adjusted for any goodwill and intangible assets from the original purchase. Unlike cost method, where the investment account stays frozen until impairment, equity method investments continuously change. An equity method investment can never drop below zero (an investor’s maximum loss equals the investment) unless the subsidiary pays distributions exceeding the investment basis, which reverses in future periods.
When Fair Value Changes and How to Record the Adjustment
Fair value adjustments flow through either net income or other comprehensive income depending on your accounting election under ASC 321 equity investments or earlier guidance. The choice matters because comprehensive income adjustments do not hit the income statement directly—they accumulate in shareholders’ equity as a separate line until the investment is sold. If you elect fair value through net income, a 10% increase in fair value creates a 10% increase in your investment’s contribution to earnings that period.
This creates earnings volatility tied to market conditions rather than your operations. If you elect fair value through other comprehensive income, the same 10% increase bypasses net income and accumulates in equity, which reduces earnings volatility but shifts the value change to the balance sheet. Once you sell the investment, any accumulated other comprehensive income reverses into net income as a realized gain or loss.
This timing difference between the fair value adjustment (recorded over multiple periods) and the realization (recorded on sale) requires careful tracking. Auditors specifically look for companies that misclassify fair value adjustments or fail to properly accumulate comprehensive income adjustments across multiple periods. Getting these mechanics right prevents restatement risk and audit complications.
The SEC and Audit Implications of Improper Revaluation
The SEC requires public companies to follow FASB investment guidance and disclose the accounting method, valuation assumptions, and sensitivity of fair value estimates to key assumptions. When companies fail to revalue investments that should be revalued, or revalue investments incorrectly, the SEC can issue comment letters requiring restatement or correction in subsequent filings. These letters become public and signal to investors that the company has accounting deficiencies.
Auditors specifically test whether management identified all triggering events that require impairment testing. They verify whether management’s fair value estimates are reasonable by comparing them to external appraisals, market data, and peer company valuations. When the auditor’s fair value estimate differs materially from management’s estimate, the auditor may require adjustment or may qualify the audit opinion, which signals to financial statement users that the company and auditor disagree on fair value.
Material misstatements in subsidiary investment accounting can trigger restatements, audit opinion qualifications, or even investigation by the SEC’s Division of Corporation Finance. Companies with improper investment accounting also face heightened scrutiny in subsequent audits and may require more experienced auditors or specialists. The financial statement impact of these issues often extends beyond the investment account itself to goodwill, intangible assets, and purchase accounting adjustments related to the subsidiary acquisition.
Mistakes to Avoid With Subsidiary Investment Revaluation
Mistake 1: Failing to Test for Impairment When Triggering Events Exist
Many companies document that a subsidiary has lost customers, faced new competition, or reported declining revenues, yet they never perform impairment testing. Management assumes the decline is temporary or plans to turn the business around, so impairment is not “really” necessary. This reasoning creates a material overstatement of the investment’s value on the balance sheet.
The consequence is that the investment remains recorded at its full carrying value despite economic evidence that its value has declined. When the auditor discovers the missing impairment test, the company must go back and estimate fair value as of the balance sheet date, likely resulting in a significant adjustment. If the impairment is discovered after financial statements are issued, the company may need to restate prior financial statements, which damages credibility with investors and regulators.
Mistake 2: Confusing Cost Method With Never Needing to Revalue
Some companies believe that once they choose cost method accounting, the investment value is literally frozen forever and impairment testing does not apply. Cost method does not require frequent revaluation like equity or fair value methods, but it absolutely requires impairment testing. Skipping impairment testing because you use cost method is a fundamental misunderstanding that auditors always catch.
The consequence is overstated assets and understated losses. If a cost method investment becomes impaired and you do not write it down, your total assets are overstated, which inflates key financial ratios like return on assets and debt-to-equity ratios. This overstatement can mislead lenders who rely on financial statements for credit decisions or investors who rely on ratios for valuation comparisons.
Mistake 3: Using Equity Method Without Tracking Goodwill and Intangibles
When you initially acquire a subsidiary and pay more than book value, the excess amount represents goodwill or identifiable intangible assets. Under equity method accounting, you must track these amounts separately and amortize or test them for impairment. Some companies forget to adjust the equity method income calculation for goodwill amortization, creating overstated earnings.
The consequence is inflated earnings each period the subsidiary is held under equity method. Over five to ten years, the accumulated overstatement can become quite material. When an auditor traces the equity method calculation and discovers the missing goodwill amortization, the company must restate prior periods’ earnings, which can trigger covenant violations in debt agreements tied to earnings thresholds.
Mistake 4: Incorrectly Applying Fair Value With Unobservable Assumptions
Companies sometimes estimate subsidiary fair values using highly aggressive assumptions about future growth, margin expansion, or discount rates without supporting market evidence. They might project 25% revenue growth indefinitely in an industry growing at 3%, or use discount rates that are 300 basis points below peer company rates without justification. The consequence is overstated fair value estimates that do not survive auditor scrutiny or are later contradicted by actual market transactions.
If you later sell the subsidiary for significantly less than your fair value estimate, the auditor and SEC will question why your valuation was so far off. The company may face audit opinion qualification or SEC investigation if management’s valuations appear deliberately aggressive or misleading. Maintaining conservative, defensible fair value assumptions protects both the company’s reputation and compliance status.
Mistake 5: Forgetting to Eliminate Intercompany Transactions in Equity Method
Under equity method accounting, you must eliminate profits on intercompany sales between the parent and subsidiary. If the subsidiary sells inventory to the parent at a markup and the parent has not sold the inventory to third parties, that profit is not yet realized from a consolidated perspective and must be deferred. The consequence is overstated equity method earnings if you forget to eliminate these intercompany profits.
The equity method investment account also becomes overstated because it reflects the subsidiary’s reported earnings without elimination adjustments. Large intercompany transaction volumes can create material misstatements if not addressed. Auditors specifically ask about intercompany transactions and verify that elimination calculations are included in the equity method income calculation.
Dos and Don’ts for Subsidiary Investment Revaluation

|---|---|
| Document impairment triggers in writing each quarter | Assume stable market conditions mean no impairment testing |
| Perform annual fair value recalculations using market data and peer comparables | Use subjective assumptions without supporting market evidence |
| Eliminate intercompany transactions from equity method earnings calculations | Report equity method earnings without accounting for intercompany eliminations |
| Review ownership structure changes immediately and adjust accounting methods | Delay accounting method changes when control is gained or lost |
| Track goodwill and intangibles separately and test annually for impairment | Group subsidiary goodwill with parent company goodwill without proper allocation |
| Engage external appraisers for material fair value estimates | Rely solely on management estimates for high-value subsidiaries |
| Disclose revaluation assumptions and sensitivities in footnotes | Bury or minimize disclosure of fair value methodologies |
| Reconcile equity method investment to subsidiary net book value monthly | Assume equity method calculations are correct without verification |
| Document the basis for fair value elections in writing at adoption | Change fair value elections without clear business purpose |
| Test for impairment before significant subsidiary announcements occur | Wait until after negative news to consider impairment testing |
Pros and Cons of Different Revaluation Approaches

|---|---|
| Cost Method | Does not reflect economic reality; investment can become significantly understated over time |
| Equity Method | Creates earnings volatility tied to subsidiary performance; complex intercompany elimination adjustments |
| Fair Value | Significant period-to-period earnings volatility; fair value expertise and appraisals required |
Real Examples: How Revaluation Plays Out in Practice
Example 1: A Holding Company’s Private Subsidiary Acquisition
A holding company buys a 100% stake in a manufacturing subsidiary for $50 million cash. The holding company elects equity method accounting for its parent-only statements. In Year 1, the subsidiary earns $5 million net income and pays $2 million in dividends. The investment account increases by $3 million (earnings minus dividends) to a carrying value of $53 million.
In Year 2, the manufacturing industry enters a downturn and the subsidiary’s customer base shrinks. The subsidiary reports a loss of $8 million and pays no dividends. The holding company’s equity method investment account decreases by $8 million to $45 million. The holding company’s separate income statement reports an $8 million equity method loss that period. In Year 3, the holding company’s management decides to explore a sale and an independent appraiser values the subsidiary at $42 million based on comparable company multiples and discounted cash flows.
The equity method carrying value is $45 million. Management recognizes a $3 million impairment loss and reduces the investment to $42 million. When the company eventually sells the subsidiary for $42 million, the carrying value matches the sale price, resulting in no gain or loss on the sale itself. This example shows how equity method revaluation through earnings and losses, combined with impairment testing, tracks economic reality more closely than cost method would have done.
Example 2: A Manufacturing Parent With a Foreign Subsidiary
A U.S. manufacturing parent owns 75% of a German subsidiary that it consolidates in group financial statements. The parent-only statements show the investment at equity method. In Year 1, the subsidiary earns euros equivalent to $4 million USD and the investment carrying value reflects this equity method adjustment. In Year 2, the euro weakens significantly against the dollar and the subsidiary’s translated earnings decrease due to currency effects alone (operations are actually stable).
Under equity method parent-only statements, the investment value decreases due to the currency translation. Under consolidated statements, the subsidiary’s assets decrease in USD terms, but no goodwill impairment occurs because the business fundamentals remain sound. The disconnect between parent-only and consolidated statements creates confusion unless properly explained in footnotes. Management must clarify that the parent-only investment decline reflects currency translation effects rather than business deterioration.
Example 3: A Private Equity Firm’s Portfolio Company Exit
A private equity firm owns 60% of a portfolio company it acquired five years ago. In Year 1-3, the firm held the investment at cost because it had passive financial investment status and did not consolidate. In Year 4, the portfolio company’s EBITDA doubled due to strong operational performance, triggering an annual fair value review. An appraiser valued the company at $150 million based on comparable company multiples; cost basis was $100 million.
The private equity firm recognized an unrealized gain of $50 million (60% ownership × $100 million increase) through other comprehensive income. In Year 5, the portfolio company’s largest customer announced it would move to a competitor. The private equity firm identified an impairment trigger and engaged an appraiser. Fair value decreased to $120 million, and the firm recorded a $30 million loss (60% × $100 million decrease from year 4 peak). In Year 6, the private equity firm sold its stake for $130 million, earning a gain above its Year 5 carrying value.
The transaction ultimately validated the fair value estimates over the holding period, with marks generally tracking market pricing. This example demonstrates how fair value accounting creates period-to-period volatility but ultimately provides more economic insight than cost method would provide over the full investment hold period.
Example 4: Ownership Change From Significant Influence to Control
A company initially purchases 35% of a manufacturing business and accounts for it using the equity method. The investment carrying value reaches $12 million after accounting for three years of equity method adjustments. The company then acquires an additional 30% stake from another shareholder, increasing its ownership to 65% and gaining control.
At the acquisition date, the company engages an independent appraiser who values the entire manufacturing business at $30 million. The 65% stake has a fair value of $19.5 million. The company must remeasure its original 35% stake at fair value as if it had just been acquired, with fair value of $10.5 million. The difference between the previous equity method carrying value ($7 million for the 35% stake) and the new fair value ($10.5 million) creates a $3.5 million gain.
Additionally, the company recognizes goodwill of $2.5 million because the total purchase price ($19.5 million current stake + implied value of $7 million for original stake = $26.5 million total) exceeds the fair value of net assets acquired (roughly $20 million). After the acquisition, the company consolidates the subsidiary rather than using equity method. This example shows how ownership changes trigger accounting method changes and revaluation to fair value.
Example 5: Cost Method Investment With Delayed Impairment Testing
An industrial company purchases a 70% stake in a supply chain subsidiary for $25 million and elects cost method accounting because it maintains passive financial involvement. Over the first three years, the subsidiary performs well and pays consistent dividends. The investment account stays at $25 million on the parent’s balance sheet. In Year 4, the subsidiary’s largest customer (representing 70% of subsidiary revenue) announces it will source directly from manufacturers instead of using the subsidiary as a distributor.
The company’s finance team documents this loss-of-customer event in a meeting memo but does not perform impairment testing. Instead, management believes the subsidiary can develop new customers and recover. In Year 5, the subsidiary’s revenue has declined 65% and operating losses have accumulated. An independent appraisal performed by the company’s auditor values the subsidiary at approximately $8 million based on discounted cash flows of the remaining customers.
The company is forced to recognize a $17 million impairment loss ($25 million carrying value minus $8 million fair value). This massive adjustment appears on the income statement and reduces the company’s reported profits by 28% that year. Additionally, the company’s debt covenants tied to earnings are violated because the impairment loss is so large. Lenders issue a covenant waiver but increase the interest rate, costing the company an additional $500,000 annually in interest expense.
Had the company performed impairment testing in Year 4 when the trigger event occurred, the company could have written down the investment gradually over time or adjusted business operations earlier. This example illustrates why deferring impairment testing under cost method creates significant risk of large, concentrated losses later.
Frequently Asked Questions About Subsidiary Investment Revaluation
Q1: If I own 51% of a company, must I consolidate, or can I use equity method?
Yes, you must consolidate under both U.S. GAAP and IFRS when control exists (typically >50% ownership). Consolidation is not optional.
Q2: Can I switch from equity method to fair value without special circumstances?
No, you can elect fair value only if you have no significant influence (typically <20% ownership). If you have significant influence, equity method is required.
Q3: Does impairment testing apply only to cost method investments?
No, impairment testing applies to all investment types when triggering events exist. Equity method and fair value investments also require impairment evaluation.
Q4: When I record an impairment loss, can I reverse it in future periods if the subsidiary recovers?
No, under U.S. GAAP, impairment losses are not reversible. Once written down, the new fair value becomes the investment’s cost basis.
Q5: How often must I test fair value investments for impairment?
Annually, at minimum, for all fair value investments with potential impairment triggers. Some companies test quarterly if significant volatility occurs.
Q6: Can I keep a subsidiary at cost basis on my parent-only statements while consolidating in group statements?
Yes, this is standard practice for public companies. Parent-only statements show the investment using cost or equity method; consolidated statements eliminate the investment.
Q7: If fair value is unobservable, can I just estimate it however I want?
No, even Level 3 (unobservable) fair values must be reasonable and supported by evidence. You must disclose assumptions and perform sensitivity testing.
Q8: Does the purchase price of the subsidiary affect ongoing revaluation requirements?
No, historical purchase price does not prevent impairment. A subsidiary bought for $100 million can still be impaired to $40 million if fair value declines.
Q9: What happens to goodwill if I increase ownership from 30% to 60% and gain control?
You must remeasure the original 30% investment at fair value and recognize goodwill on both old and new portions as if you had just acquired 100%.
Q10: Can I avoid impairment testing by simply not looking for triggering events?
No, auditors will identify triggering events through their own procedures. Ignoring obvious events is not a valid audit defense.
Q11: If I elect fair value through other comprehensive income, do I eventually record the gain?
Yes, when you sell the investment, accumulated other comprehensive income reverses into net income as a realized gain or loss.
Q12: What if my subsidiary is bankrupt—must I keep the investment on the books?
No, if fair value reaches zero or becomes immaterial, you can write the investment down to zero or write it off entirely.
Q13: Are there any exceptions where revaluation is not required?
No exceptions exist for controlling subsidiary investments under U.S. GAAP except in specialized industries (insurance or specific financial institutions).
Q14: If I have a guarantee on my subsidiary’s debt, does that change revaluation rules?
No, the guarantee affects your liability accounting but not the subsidiary investment accounting. Both must be evaluated independently.
Q15: How does a subsidiary acquisition contingency affect my initial investment revaluation?
At initial recognition, you record the investment at cost including contingent consideration at fair value. Future contingent amount changes create adjustments to goodwill only.
