Accounting fraud disputes may begin with irregularities such as unusual journal entries, unsupported revenue, omitted liabilities, or questionable estimates. Further testing may help assess whether the issue reflects error, disputed accounting judgment, control weakness, or intentional manipulation.
For attorneys and claims professionals, a qualified accounting expert witness or forensic accountant may help reconstruct records, test disputed transactions, evaluate accounting treatment, and explain what the financial evidence supports.
This guide explains common accounting fraud issues, investigative methods, and reliability considerations that matter in litigation.
What Is Accounting Fraud?
In the financial-reporting context, suspected accounting fraud may involve intentional manipulation, falsification, omission, or misapplication of accounting information. Whether particular conduct legally constitutes fraud depends on the governing law and the facts.
In the financial-statement audit context, PCAOB AS 2401 identifies whether the action causing the misstatement was intentional as the primary factor distinguishing fraud from error. Its framework addresses two categories of fraud-related misstatement:
- Fraudulent financial reporting, including intentional misstatements or omissions intended to deceive financial statement users when they result in a material misstatement, such as falsifying supporting records or intentionally misapplying accounting principles.
- Misappropriation of assets, such as theft, embezzlement, or causing an entity to pay for goods or services not received, when the conduct results in a material misstatement of the financial statements.
A forensic accountant can analyze evidence relevant to these issues, but an accounting irregularity does not by itself establish fraud.
Common Accounting Irregularities Experts May Investigate
Revenue Recognition Issues
Disputes may involve unsupported sales, premature recognition, side agreements, unusual period-end transactions, or entries that do not match delivery, acceptance, or payment records.
An expert may compare ledger entries with contracts, invoices, shipping records, customer records, cash receipts, and applicable accounting guidance.
Omitted Liabilities or Misclassified Expenses
Financial results can be distorted when liabilities are omitted or expenses are recorded in an inappropriate period or category. An expert may review accruals, vendor records, subsequent payments, capitalization decisions, legal contingencies, and period-end adjustments.
Journal Entries, Estimates, and Unusual Transactions
Management override and nonstandard journal entries may deserve closer review when financial statement manipulation is suspected. Period-end entries, unusual users or accounts, unsupported adjustments, possible bias in estimates, or significant transactions outside the ordinary course of business may warrant testing, but they do not by themselves establish intent.
How Forensic Accountants Test Accounting Irregularities
A well-supported investigation of suspected accounting fraud generally ties its conclusions to identifiable source records and clearly explains how the analysis was performed.
Establish the Data Foundation
Experts may define the relevant entities, time period, accounts, systems, and disputed transactions, then review records such as general ledgers, subledgers, bank statements, invoices, contracts, payroll records, audit workpapers, emails, and system exports. If data is filtered, transformed, or combined, documenting those steps can help show how the analysis was performed.
Test Transactions and Accounting Entries
Depending on the allegations, testing may include:
- Tracing entries to supporting documents
- Comparing transactions with bank activity or third-party records
- Testing period-end and manual journal entries
- Reviewing related-party activity
- Comparing results with historical or operational patterns
- Evaluating significant estimates and unusual transactions
- Using data analytics to identify transactions for further review
Analytical tools can narrow the records requiring closer review, but unusual patterns may warrant further investigation and are not, by themselves, proof of fraud.
Evaluate Alternative Explanations
An irregularity may reflect fraud, error, weak controls, incomplete records, or disputed accounting judgment. A careful analysis should consider reasonable alternative explanations and identify limitations in the available evidence.
When an Accounting Expert Witness May Be Useful
An accounting expert can assist with disputes involving financial records, accounting treatment, transaction tracing, internal controls, or suspected misstatements.
Depending on the case, the expert may evaluate competing explanations, reconstruct incomplete information, quantify disputed amounts, or prepare opinions for deposition or trial. Early involvement may also help identify financial data that counsel may want to address in discovery and preservation planning.
Reliability of Accounting Expert Testimony
In federal proceedings governed by the Federal Rules of Evidence, Rule 702 sets the standard for expert testimony. A witness must first be qualified as an expert by knowledge, skill, experience, training, or education.
The proponent must then show the court, more likely than not, that the expert's specialized knowledge will help the trier of fact understand the evidence or determine a fact in issue and that the testimony is based on sufficient facts or data. The proponent must also show that the testimony is the product of reliable principles and methods and that the expert's opinion reflects a reliable application of those principles and methods to the facts of the case.
In practice, accounting expert testimony may be evaluated in light of factors such as whether the expert's qualifications fit the disputed issue, whether the analysis has an adequate data foundation, whether calculations are shown clearly when calculations are used, whether the methods are appropriate, and whether the conclusions stay within what the analysis supports. State evidentiary standards may differ.
