What are the real-world differences between accrual and cash basis accounting, and why does the CFA curriculum focus on accrual?

Accrual accounting records economic events when they occur, regardless of when cash changes hands. Cash basis accounting records transactions only when cash is received or paid. The CFA curriculum emphasizes accrual because it provides a more accurate picture of a company's financial performance over a period.

Core Principle

Under accrual accounting, revenue is recognized when earned (goods delivered or services performed) and expenses when incurred (resources consumed), not when cash moves. This matching of revenues and expenses in the same period gives analysts a meaningful view of profitability.

Example: Orion Logistics Inc. ships $120,000 of freight services to Beachside Retail in December 2025 on 60-day credit terms. Under accrual, Orion records $120,000 revenue in December because the service is complete. Under cash basis, the revenue would not appear until February 2026 when Beachside pays. If you are analyzing Orion's Q4 profitability, the accrual method captures the economic reality of December, while cash basis would understate Q4 and overstate Q1.

Why Accrual Matters for Analysts

1. Matching principle -- Expenses like wages earned by employees in December but paid in January are recognized in December, matching the period the work was done.
2. Comparability -- IFRS and US GAAP both require accrual accounting for publicly traded companies, making cross-company comparison possible.
3. Predictive value -- Accrual income is a better predictor of future cash flows than current-period cash receipts because it smooths timing differences.

When Cash Basis Is Used

Small private businesses and some tax filings permit cash basis because of its simplicity. However, no major financial reporting framework accepts it for public companies.

Exam Tip: If a question describes a company that collected cash before delivering goods, under accrual accounting the cash received is recorded as a liability (unearned revenue), not revenue. This distinction is heavily tested.
