CPA Exam FAR Deep Dive — US GAAP, Financial Instruments, and Consolidations

CPA FAR vs. Other Accounting Exams

FAR is consistently rated the hardest CPA section, and for good reason.

Key FAR Topics — Financial Instruments

ASC 326 — Current Expected Credit Loss (CECL)

Classification of Debt Securities

• HTM (Held-to-Maturity): positive intent and ability to hold to maturity; reported at amortized cost
• AFS (Available-for-Sale): unrealized gains/losses in OCI; impairment through net income
• Trading: unrealized gains/losses through net income (like IFRS FVPL)

CECL Credit Loss Model (ASC 326, effective for most companies)

Stage Equivalent	Condition	Allowance Measurement
General (all financial assets)	At origination	Lifetime expected credit loss
AFS debt securities	Fair value below amortized cost	ACL limited to the amortized cost–fair value difference

Note: Unlike IFRS 9’s 3-stage ECL model, US GAAP CECL requires lifetime expected credit loss at origination for most instruments — a more conservative approach than IFRS Stage 1 (12-month ECL).

Effective Interest Method

Beginning carrying amount × effective interest rate = interest income
Interest income − cash interest received = amortization of discount
Ending carrying amount = beginning + amortization (discount bonds)

ASC 606 — Revenue Recognition

The 5-step model is equally central for FAR. CPA FAR frequently tests variable consideration and contract modifications.

Variable Consideration

• Expected value method: probability-weighted sum of possible outcomes
• Most likely amount method: single most likely outcome
• Constraint: include variable consideration only to the extent it is highly probable that a significant revenue reversal will not occur

Contract Modifications

Scenario	Accounting Treatment
Separate contract	New goods/services are distinct AND priced at standalone selling price
Termination of old + new contract	Distinct goods/services but NOT at standalone selling price
Modification of existing contract	Goods/services NOT distinct → cumulative catch-up adjustment

ASC 842 — Leases

Lessee Initial Measurement

Lease liability = PV of remaining lease payments (at lessee's
                  incremental borrowing rate if implicit rate unknown)
Right-of-use asset = Lease liability
                   + Lease incentives paid to lessor
                   + Initial direct costs
                   + Prepaid lease payments
                   − Lease incentives received

Subsequent Measurement

• Lease liability: effective interest method; reduced by principal payments
• ROU asset (operating lease): straight-line amortization over lease term
• ROU asset (finance lease): amortized over shorter of lease term or useful life; interest on lease liability recorded separately

ASC 740 — Income Taxes (Deferred Tax)

Deferred Tax Calculation Flow

① Compare book carrying value vs. tax basis for each asset/liability
② Compute temporary differences
   - Taxable temporary difference → Deferred tax liability
   - Deductible temporary difference → Deferred tax asset
③ Apply enacted future tax rate (when difference reverses)
④ Assess valuation allowance for deferred tax assets
   (more-likely-than-not criterion)

ASC 450 — Contingencies

Contingent Liability Recognition

Probability	Estimable?	Treatment
Probable	Yes	Accrue (debit expense, credit liability)
Probable	No	Disclose in footnotes
Reasonably possible	Either	Disclose in footnotes
Remote	Either	No disclosure required (unless guarantee)

ASC 350 / ASC 360 — Intangibles and Impairment

• Internally developed intangibles: research phase → expense; development phase → capitalize only under strict criteria (not as broad as IFRS IAS 38)
• US GAAP generally expenses all internal development costs (ASC 730); software for internal use is an exception (ASC 350-40)

Cost Accounting Topics in FAR

Absorption vs. Variable Costing — Operating Income Difference

Absorption costing OI − Variable costing OI
= Ending inventory units × Fixed overhead per unit
  − Beginning inventory units × Fixed overhead per unit

When production > sales → absorption costing income is higher (fixed overhead deferred in ending inventory).

Balanced Scorecard — Four Perspectives

Perspective	Key Question	Sample Metrics
Financial	How do we look to shareholders?	ROI, EVA, revenue growth
Customer	How do customers see us?	Satisfaction scores, market share
Internal Process	Where must we excel?	Defect rate, cycle time
Learning & Growth	How can we improve?	Employee training hours, turnover

Quality Cost Analysis — Four Categories

• Prevention costs: costs to prevent defects (design reviews, employee training)
• Appraisal costs: costs to inspect (finished goods inspection, quality audits)
• Internal failure costs: defect costs before shipment (rework, scrap)
• External failure costs: defect costs after shipment (warranty, returns)

Increasing prevention and appraisal costs should reduce internal and external failure costs — a classic trade-off.

Task-Based Simulation (TBS) Strategy

Response Format for Calculation TBSs

[Given information]
- Applicable standard: ASC 606 (Revenue Recognition)
- Number of performance obligations: 2
  (software license + maintenance service)

[Calculations]
① Standalone selling prices: Software $900,000; Maintenance $300,000
② Allocation ratios: Software 75%, Maintenance 25%
③ Transaction price $1,000,000 allocated:
   - Software: $750,000
   - Maintenance: $250,000

[Answer]
Revenue recognized in the period:
- Software (point-in-time): $750,000
- Maintenance (ratably over 12 months; 3 months elapsed): $62,500
- Total: $812,500
