ACC-421: Auditing and Forensic Accounting

A study guide to ACC-421 at SNHU, the forensic accounting course on classic fraud types, red flags and how fraud is detected, prevented and deterred.

Updated October 2026 · 5 min read

ACC-421 at Southern New Hampshire University is Auditing and Forensic Accounting, part of the forensic accounting and fraud examination concentration in SNHU's BS in Accounting.

SNHU describes it as teaching classic fraud types and the impact fraud can have on an organization. Students identify red flags associated with occupational fraud types, analyze methods to detect, prevent and deter fraud, and discuss the legal impacts of fraud examination procedures.

Forensic work demands a different mindset from routine accounting. You assume nothing, look for patterns that do not fit and document everything as if it might be examined in court. Students often find the shift from "does this balance?" to "why does this look wrong?" both interesting and challenging.

Key Concepts Explained

The Fraud Triangle

Criminologist Donald Cressey's work led to the fraud triangle: pressure (a financial or personal need), opportunity (weak controls or trust) and rationalization (a story that justifies the act). Controls mainly reduce opportunity, which is the side an organization can influence most.

Example: A long-serving bookkeeper with mounting personal debts (pressure) handles receipts, deposits and reconciliations alone (opportunity) and tells herself she is "borrowing" until payday (rationalization). Splitting those duties and adding independent review removes the opportunity.

Occupational Fraud Categories

Fraud examiners commonly group occupational fraud into asset misappropriation (such as skimming, billing schemes and payroll fraud), corruption (such as bribery and conflicts of interest) and financial statement fraud. Each has typical red flags.

Example: In a shell company billing scheme, red flags include a vendor with only a P.O. box, invoices just below an approval limit, sequential invoice numbers and an employee who never takes leave. Matching the vendor master file against employee addresses is a common detection test.

Typical Assignments and How to Approach Them

Legal discussionUnderstanding legal impactsExplain how procedures protect evidence and rights

SNHU's description includes the legal impacts of fraud examination procedures. Findings are only useful if they can be relied on in disciplinary, civil or criminal proceedings. That means gathering evidence lawfully, preserving it in its original form, documenting the chain of custody and avoiding accusations before the facts are established.

In written work, show awareness of these limits. Describe what an examiner would do, how evidence would be preserved and when legal counsel should be involved. Avoid concluding that a named person is guilty; examiners report facts and findings, and guilt is decided by courts or other proper processes.

Recommendations should also consider deterrence. People are less likely to commit fraud when they believe they will be caught, so visible measures such as surprise audits, mandatory leave, rotation of duties and a well-publicized reporting hotline can be as valuable as detective controls.

Explain which side of the fraud triangle each measure addresses and what it would cost to run.

Finally, connect your analysis to the organization in the case: its size, industry and culture. A control that suits a large company may be impractical for a small one, where owner review and compensating controls may be the realistic answer.
