The ACFE Fraud Triangle
Employee fraud occurs when three conditions align: Opportunity (access to assets and weak controls), Pressure (financial stress or lifestyle demands), and Rationalisation (convincing oneself the fraud is justified). Effective prevention addresses all three elements.
Reduce opportunity through segregation of duties, approval thresholds, and regular reconciliations. Address pressure through employee support programmes and fair compensation. Counter rationalisation through clear ethical standards and visible enforcement.
Internal Controls Framework
Key controls for employee fraud prevention include: segregation of duties in finance and payroll functions; dual authorisation for payments above thresholds; regular bank reconciliations and exception reporting; vendor master file controls; expense claim analytics and random audits; and access controls on financial systems.
Controls must be proportionate to the organisation's size and fraud risk profile. A large organisation with 500 employees and £50m turnover requires more robust controls than a small business.
FTPF Reasonable Procedures
Under ECCTA 2023, organisations must demonstrate reasonable fraud prevention procedures to establish a defence against the Failure to Prevent Fraud offence. MOJ guidance identifies six principles: top-level commitment; fraud risk assessment; proportionate procedures; due diligence; communication and training; and monitoring and review.
Procedures must be documented, implemented, and regularly reviewed. An expert advisory review can identify gaps and recommend improvements before an offence occurs.
Expert Advisory Role in Controls Assessment
Forensic accountants conduct independent assessments of fraud prevention controls, benchmarking against industry standards and MOJ guidance. The assessment identifies control gaps, prioritises improvements, and produces documentation supporting the reasonable procedures defence.
Expert advisory engagements are increasingly requested by audit committees, compliance teams, and external auditors evaluating FTPF readiness.
Red Flags and Detection
Detection mechanisms include: automated exception reporting in payroll and accounts payable; expense claim analytics; whistleblowing hotlines; regular internal audit reviews; and management review of financial reports. Employees who never take holiday, resist audit scrutiny, or display lifestyle inconsistent with salary are behavioural red flags requiring investigation.
Early detection limits loss and strengthens the organisation's position in any subsequent FTPF proceedings by demonstrating active monitoring.
