Putting It Together: The Investor's Audit Checklist

Before committing capital to any company, run a five-point audit quality checklist. It takes 15 minutes per company and can prevent catastrophic losses from accounting failures.

§ 01
#CheckWhere to Find ItRed Flag
1Audit opinion unqualified?10-K, before financial statementsQualified, adverse, or disclaimer
2No going concern language?Emphasis of Matter paragraphGoing concern doubt expressed
3Clean Section 404 controls?Management’s Report on Internal ControlMaterial weakness disclosed
4Consistent auditor (3+ years)?10-K cover + Form 8-K historyFrequent changes, Big Four → small
5No financial red flags?3-year ratio trendsReceivables/inventory growing faster than revenue
§ 02

A single failed check does not automatically disqualify a company. But multiple failures compound risk exponentially. Two or more red flags should significantly increase your required margin of safety or prompt you to pass entirely.

§ 03
Run the 5-point audit checklist on a company you own or are considering. Start with the audit opinion, then check Section 404, auditor history, and 3-year ratio trends.
§ 04
Your checklist: (1) Clean audit, (2) Clean controls, (3) Same auditor 10 years, (4) No ratio red flags, but (5) CFO resigned and a depreciation estimate change boosted earnings by 8%. Assessment?
§ 05

The audit checklist is a risk calibration tool. Clean checks lower required margin of safety. Failed checks raise it. The discipline of running it prevents you from falling in love with a stock’s story while ignoring cracks in its accounting foundation.

§ 06
You've audit-reviewed a company: clean opinion, no going-concern flags, no material weakness, strong internal controls. Is it safe to invest?
