- Prepare journal entries for acquisitions, fair value changes, income recognition, dividends, and disposals
The Core Idea: Classification Drives Everything
Here is the structural reality of investment accounting: there is no single "investment" account. The moment an entity acquires a financial asset, the accounting system must classify it — and that classification decision locks in the measurement basis, the income recognition pattern, the impairment model, and the balance sheet presentation. Get the classification right and everything else follows mechanically. Get it wrong and every subsequent entry is wrong.
This is not a memorization exercise. It is a routing problem. The investor arrives at the classification gate carrying two pieces of information: what kind of instrument is this (debt vs. equity) and what is the investor's relationship to it (intent, influence, ability). The answers route the investment into one of four lanes, and each lane has its own complete set of accounting rules.
The framework below is the routing map. Learn it as a decision process, not a list.
Investment Classification and Measurement
Investment Classification: How to Account for a Financial Asset
The four main investment classifications for financial assets. Trading and AFS are at fair value (through income or OCI respectively). HTM is at amortized cost. Twenty-percent (20-50%) triggers the equity method. Classification drives measurement, income recognition, and impairment treatment.
An entity acquires 15% of a company's voting stock with no intent to actively trade. The stock trades on the NYSE. How is this investment classified?
Lane 1: Fair Value Through Net Income
This is the default lane for equity securities and the required lane for trading debt securities. The logic is simple: measure at fair value each period, and run all changes through the income statement.
Equity Securities (ASC 321)
Under ASC 321, all equity securities with readily determinable fair values are measured at fair value through net income. There is no "available-for-sale" classification for equity securities — that ended with ASU 2016-01.
Key mechanics:
- Measure at fair value each reporting period
- Unrealized gains and losses hit net income — not OCI
- No separate impairment model needed (fair value changes already flow through earnings)
- Dividends recognized as income when received
Purchase:
| Account | Debit | Credit |
|---|---|---|
| Investment in Equity Securities | XXX | |
| Cash | XXX |
Fair value increase at period end:
| Account | Debit | Credit |
|---|---|---|
| Investment in Equity Securities | XXX | |
| Unrealized Gain on Investments | XXX |
Dividend received:
| Account | Debit | Credit |
|---|---|---|
| Cash | XXX | |
| Dividend Income | XXX |
Equity Securities Without Readily Determinable Fair Values
When fair value is not readily determinable, the entity may elect a measurement alternative under ASC 321: report at cost minus impairment, adjusted for observable price changes in orderly transactions for identical or similar investments. This is a practical accommodation — the entity uses cost as the anchor and only adjusts when it observes a real transaction that provides evidence of value.
Trading Debt Securities
Trading securities are debt instruments held for short-term resale. Same measurement model as equity: fair value through net income. Interest income is recognized separately (unlike equity, where dividends are the income component).
Lane 2: Fair Value Through OCI
This lane exists only for available-for-sale (AFS) debt securities and equity securities subject to an irrevocable FV-OCI election.
AFS Debt Securities
AFS is the residual category for debt securities that are neither trading nor held-to-maturity:
- Measured at fair value each period
- Unrealized gains and losses go to other comprehensive income (OCI) — not the income statement
- Reclassified ("recycled") to net income when the security is sold
- Subject to the CECL impairment model for credit losses
The OCI treatment means unrealized changes hit equity (through AOCI) but bypass the income statement. This reflects the intent: the entity is not actively trading but also has not committed to holding to maturity.
Impairment of AFS debt securities:
When fair value drops below amortized cost:
- Determine if any portion of the decline is due to credit loss (expected cash flow shortfall)
- Credit losses are recognized in net income through a reversible allowance
- The non-credit portion remains in OCI
| Account | Debit | Credit |
|---|---|---|
| Credit Loss Expense | XXX | |
| Allowance for Credit Losses — AFS | XXX |
This split is critical for exam purposes: only the credit piece hits income; the rest stays in equity.
Lane 3: Amortized Cost (Held-to-Maturity)
Held-to-maturity (HTM) debt securities require two conditions: the entity has the positive intent and the ability to hold the security until maturity. If either condition fails, the security must be reclassified to AFS.
Key mechanics:
- Measured at amortized cost (face value adjusted for unamortized premium or discount)
- No fair value adjustments on the balance sheet
- Interest income recognized using the effective interest method
- Subject to the CECL impairment model
Premium and Discount Amortization
Bond Investment Premium/Discount Amortization (Effective Interest)
Interest Revenue = Carrying Amount × Market Rate at Purchase
Cash received = Face × Stated Rate. Difference between interest revenue and cash received amortizes the premium or discount. Applies to HTM and AFS debt securities
Worked Example — Premium Bond:
An entity purchases a $100,000 bond at 104 ($104,000). Stated rate: 6%. Market rate at purchase: 5%. Semiannual payments.
Period 1:
- Cash received: $100,000 × 3% = $3,000
- Interest revenue: $104,000 × 2.5% = $2,600
- Premium amortization: $3,000 − $2,600 = $400
- New carrying amount: $104,000 − $400 = $103,600
| Account | Debit | Credit |
|---|---|---|
| Cash | $3,000 | |
| Investment in HTM Securities | $400 | |
| Interest Revenue | $2,600 |
The carrying amount converges toward face value over the bond's life. For a premium bond, cash received exceeds interest revenue each period, and the difference reduces the carrying amount. For a discount bond, the pattern reverses — interest revenue exceeds cash, and the difference increases the carrying amount.
A company buys a $50,000 HTM bond at 97. The market rate is higher than the stated rate. Each period, will interest revenue be greater than or less than cash received?
CECL Impairment for HTM
| Account | Debit | Credit |
|---|---|---|
| Credit Loss Expense | XXX | |
| Allowance for Credit Losses — HTM | XXX |
Unlike AFS, there is no credit/non-credit split — the entire fair value decline analysis is irrelevant. CECL measures only expected credit losses: the present value of cash flows the entity does not expect to collect.
Lane 4: Equity Method (ASC 323)
The equity method applies when the investor has significant influence over the investee — generally presumed at 20% to 50% ownership of voting stock. This is a fundamentally different model: instead of measuring the investment at fair value or amortized cost, the investor treats the investment as a single-line consolidation.
Indicators of significant influence beyond the 20% threshold:
- Board representation
- Participation in policy-making
- Material intercompany transactions
- Interchange of managerial personnel
- Technological dependency
The Carrying Amount Formula
Equity Method Investment Carrying Amount
Cost + Share of Investee Income − Dividends Received − Impairment
Adjust the investment account each period for the investor's proportionate share of investee net income (increase) and dividends received (decrease). Test for OTTI if indicators present
This formula captures the entire equity method lifecycle:
- Initial recognition — record at cost
- Each period — increase for share of investee income; decrease for dividends received
- Impairment — write down for other-than-temporary impairment
Why Dividends Reduce the Investment
This is counterintuitive and heavily tested. Under the equity method, dividends are not income — they are a return of investment. The investor already picked up its share of the investee's earnings through the income pickup entry. When the investee then distributes cash, it is distributing earnings the investor already recognized. Taking it as income again would be double-counting.
Income pickup:
| Account | Debit | Credit |
|---|---|---|
| Investment in Equity Method Investee | XXX | |
| Equity in Earnings of Investee | XXX |
Dividend received:
| Account | Debit | Credit |
|---|---|---|
| Cash | XXX | |
| Investment in Equity Method Investee | XXX |
Worked Example
Investor acquires 30% of Investee for $900,000. In Year 1, Investee reports net income of $200,000 and pays dividends of $50,000.
Income pickup: $200,000 × 30% = $60,000 Dividends: $50,000 × 30% = $15,000
Ending balance: $900,000 + $60,000 − $15,000 = $945,000
Basis Differences
When the investor pays more than book value for the investee's net assets, the excess is allocated to:
- Identifiable assets with fair values exceeding book values (e.g., undervalued equipment) — amortized over remaining useful life
- Goodwill — the residual; not separately amortized but considered in OTTI analysis
The amortization of basis differences reduces the investor's equity in earnings each period. This reflects the reality that the investor overpaid relative to book value, and that premium must be consumed over time.
Extended example: Investor pays $900,000 for 30% of Investee. Investee's book value of net assets: $2,400,000 (investor's share: $720,000). Fair value of equipment exceeds book by $200,000 (investor's share: $60,000, remaining life 10 years). Goodwill: $900,000 − $720,000 − $60,000 = $120,000.
Each year, amortization of equipment basis difference: $60,000 / 10 = $6,000 reduction to equity in earnings.
Impairment
Equity method investments use the other-than-temporary impairment (OTTI) model — not CECL. If the decline in value is judged to be other than temporary, write down to fair value. This loss is not reversible.
An investor owns 25% of an investee. The investee reports a net loss of $100,000 and pays no dividends. What is the effect on the investment's carrying amount?
The Complete Comparison
Investment Categories — Measurement and Income Recognition
| Category | Measurement | Unrealized Gains/Losses | Impairment Model |
|---|---|---|---|
| Trading (debt) | Fair value | Net income | CECL (ASC 326) |
| Available-for-sale (debt) | Fair value | OCI (reclassify on sale) | CECL (ASC 326) |
| Held-to-maturity (debt) | Amortized cost | Not recognized | CECL (ASC 326) |
| Equity (default) | Fair value | Net income | N/A (FV measurement) |
| Equity (FV-OCI election) | Fair value | OCI (no recycling) | N/A (FV measurement) |
| Equity (measurement alt.) | Cost − impairment ± observable changes | Adjust for observable price changes | Qualitative, then quantitative if indicated |
| Equity method (20-50%) | Cost + share of income − dividends | Not applicable | OTTI assessment |
Impairment Models at a Glance
The impairment model depends entirely on the classification lane:
| Lane | Model | Trigger | Measurement |
|---|---|---|---|
| FV through NI | None needed | FV changes flow through income | N/A |
| FV through OCI (AFS debt) | CECL | Credit loss component | Allowance = expected credit losses |
| Amortized cost (HTM) | CECL | Expected credit losses | Allowance = PV of cash flows not expected to collect |
| Equity method | OTTI | Decline other than temporary | Write down to fair value (permanent) |
| Measurement alternative | Qualitative | Impairment indicators present | Quantitative if qualitative fails |
Software Cost Capitalization
Software development costs follow a specialized capitalization model that depends on the software's intended use. This decision tree routes to the correct standard:
Software Cost Capitalization
External-Use Software (ASC 985)
Costs are expensed until technological feasibility is established (typically when a detailed program design or working model is completed). After that milestone:
- Capitalize coding, testing, and production costs
- Stop capitalizing when available for general release
- Amortize at the greater of revenue ratio or straight-line over remaining useful life
- Report at the lower of unamortized cost or NRV (assessed each period)
Internal-Use Software (ASC 350-40)
Three-stage model:
- Preliminary project stage — expense (conceptual planning, evaluating alternatives)
- Application development stage — capitalize (coding, testing, installation, data conversion)
- Post-implementation stage — expense (training, maintenance, minor upgrades)
Impairment Testing for Indefinite-Lived Intangible Assets
Though this impairment framework applies broadly to indefinite-lived intangible assets (covered in greater depth in the Intangible Assets lesson), the decision tree is tagged here because indefinite-lived assets often arise in investment contexts:
Impairment Testing — Indefinite-Lived Intangible Assets
Key Exam Tips
- Equity securities always go through net income — there is no AFS classification for stocks under ASC 321
- AFS debt impairment splits credit vs. non-credit — credit losses hit income through an allowance, non-credit stays in OCI
- HTM requires intent AND ability — if either is lacking, reclassify to AFS
- Equity method dividends reduce the investment — they are not income; the income was already recognized in the earnings pickup
- Basis differences must be amortized — they reduce equity in earnings each period
- Software capitalization has two different standards — ASC 985 for external (tech feasibility trigger) and ASC 350-40 for internal (application development stage trigger)
- CECL vs. OTTI — debt securities use CECL; equity method uses OTTI. Do not confuse them.
