Every public company's financial statements are prepared under a specific set of standards, audited by an external firm, and signed off with an auditor's report. The standards determine what gets recorded and how; the auditor determines whether what's reported is fair. These are separate questions — and confusing them is a common analyst mistake.
IFRS vs US GAAP
- IFRS (International Financial Reporting Standards): published by the IASB (London). Used by ~140 countries, including all EU members, the UK, Australia, South Africa, Nigeria, Kenya, most of Africa and Asia. Principles-based — fewer specific rules, more judgement.
- US GAAP (Generally Accepted Accounting Principles): published by FASB (Connecticut). Required for US-listed companies. Rules-based — voluminous specific rules for almost every scenario.
- The two are converging — most material items are treated similarly — but real differences persist in inventory (LIFO allowed in GAAP, banned in IFRS), revenue recognition specifics, lease accounting, and treatment of development costs.
Why this matters in practice
A US-listed company files under GAAP. A London-listed company files under IFRS. The same underlying business might report slightly different earnings depending on jurisdiction. When comparing two companies across jurisdictions — say, a Kenyan bank against a US bank — be aware that headline numbers may differ for accounting reasons alone, not business reasons. The convergence project (IFRS and FASB collaborating since 2002) has reduced this but not eliminated it.
The auditor's report — four opinions
- Unqualified ('clean'): the most common. Auditor found the financial statements present fairly in accordance with the framework. Standard wording, three paragraphs. What every company aims for.
- Qualified ('except for'): auditor found a specific issue (e.g., they couldn't verify inventory in one warehouse). The rest of the statements are fine; one identified item is qualified. Concerning but not damning.
- Adverse: the financial statements as a whole do NOT present fairly. This is a damning opinion. Stock typically drops sharply on adverse opinions; lenders may pull credit. Rare.
- Disclaimer: the auditor was unable to form an opinion (e.g., key records were destroyed, management refused access). Effectively says 'we can't tell you whether this is accurate'. Treated similarly to adverse by most users.
What an audit does NOT attest
Auditors do not certify that: the business is well-managed; the strategy is sound; future performance will continue; there is no fraud (only that they found no material misstatement using their sampling procedures); insiders haven't enriched themselves through related-party transactions (those should be disclosed but might not be); the going-concern assumption is unquestionably correct (auditors flag going-concern risk if they see it, but it's a judgement). Understanding what an audit DOES NOT promise is critical for using audit reports correctly.
Reading an auditor's report systematically
- Find it: usually pages 2–4 of the annual report, signed by the auditor's office.
- Check the opinion paragraph: is it unqualified, qualified, adverse, or disclaimer?
- Read the 'Basis for opinion' and 'Key Audit Matters' sections: these flag specific judgemental areas the auditor highlights. Often the most informative part — auditors are signalling what to question.
- Note the auditor's identity and tenure: Big Four (KPMG, Deloitte, PwC, EY) are highest-bar; second-tier (Grant Thornton, BDO, Mazars) are reputable; small no-name firms auditing public companies are a warning sign.
- Check management responsibility language: management asserts the financial statements present fairly; the auditor opines on management's assertions. Both have legal exposure for false statements.
Where to go from here
Twelve modules of universal fundamentals. Every other Finance course on this platform — Financial Statements, DCF Valuation, Investment Banking, Climate Finance, Credit, Corporate Financing — assumes you can work with these tools. From here: Financial Statements teaches you how to ANALYSE the three statements; DCF teaches you how to value the business those statements describe; Investment Banking teaches you how to raise capital for that business; Credit teaches you how to lend to it. They're all built on what you just learned.
Exercise
Find the most recent annual report of a listed Kenyan company (Safaricom, Equity Bank, EABL, NSE-listed). Find the auditor's report. Identify: (1) which framework (IFRS or other); (2) which auditor (Big Four or other); (3) the type of opinion (unqualified, qualified, adverse, disclaimer); (4) the Key Audit Matters section — what specific issues did the auditor flag as judgemental?
