In financial due diligence, accuracy and reliability of financial statements are essential. One of the more effective tools to assess the completeness of financials is a procedure which reconciles recorded revenues and expenses with actual bank activity, commonly referred to as “proof of cash”. By agreeing the general ledger transactions to the cash and/or sources, proofs of cash can expose inconsistencies, clarify financial reporting and provide better informed decision making.
While a proof of cash is a great tool for assessing the completeness of financials, it is only one component of a comprehensive financial due diligence process. Other procedures typically include:
- Quality of Earnings Analysis: Adjusting earnings for non-recurring, non-operational or non-cash items to reflect a more accurate picture of ongoing profitability. Verifying the accuracy and recognition of income and costs through sampling and supporting documentation. This includes reviewing the accounting policies and practices to ensure consistency with GAAP and any deviations would be evaluated as part of our EBITDA adjustments.
- Working Capital Analysis: Assessing the quality and sustainability of current assets and liabilities.
- Tax and Legal Reviews: Identifying potential liabilities or compliance issues.
- Management Interviews and Operational Reviews: Gaining qualitative insights into business practices, internal controls, operational improvement opportunities, and post-close integration planning.
- IT and Cybersecurity: Assessing the IT infrastructure, software and governance of a target, as well as evaluating a company’s cybersecurity policies, including data protection, incident history and third-party risks. Additional procedures include assessing whether systems are appropriate for anticipated growth or if significant capital expenditures would be required.
Together, these procedures provide a holistic view of a target’s financial health, with the proof of cash serving as a foundational check on the completeness and integrity of the financials. For target’s that are not audited, a proof of cash reconciliation is vital to validate the integrity of the reported financials and ensuring the reliability of earnings. Given the potential absence of financial controls, which typically exist in an audited company, a proof of cash reconciliation adds a critical layer of financial comfort.
Understanding Proof of Cash Reconciliations
Proof of cash reconciliations involve comparing a target's financial records to actual bank activity over a given period. The reconciliation consists of two main components:
- Cash Receipts to Revenue Reconciliation: Verifies that incoming cash has been appropriately recorded as revenue and demonstrates that accounts receivable are being collected.
- Cash Disbursement to Expenses Reconciliation: Verifies that outgoing cash has been properly recorded as expenses providing increased confidence that expenses are not missing from the income statement.
Each of the two core components, cash receipts to revenue and cash disbursements to expenses, offers insight into the integrity of a company’s financial reporting. Reconciling receipts helps ensure that recorded revenue reflects actual collections, minimizing the risk of overstated sales or unrecorded deposits. On the disbursement side, tracing payments back to bank activity can expose misclassified expenses, duplicate payments or unrecorded transactions. Together, these reconciliations provide a grounded view of how cash moves through the business.
Proof of Cash in Practice
Proof of cash reconciliations are effective in identifying a wide range of discrepancies. The following section outlines commonly encountered issues, followed by key considerations for specific industries.
Common Issues
- Sales Tax Misclassification: Sales tax mistakenly recorded as revenue rather than a liability can inflate earnings.
- Unrecorded Deposits: Cash deposits received but not yet recorded as revenue can distort current-period earnings, and if related to deferred revenue, may also lead to misstated future results.
- Netted Transactions: Bank fees or other charges deducted from deposits without separate expense recording can cause classification issues.
- Duplicate Payments: Erroneously repeated payments to vendors can inflate expenses.
- Unrecorded Interbank Transfers: Bank transfers that are not properly recorded can be misclassified as revenue or expenses.
- Uncleared Checks: Checks that have been issued but not yet cleared can cause discrepancies between book and bank balances.
- Timing Differences: Cash activity recorded in one period but reflected in the bank in another can create temporary discrepancies.
- Foreign Currency Transactions: Exchange rate variances can result in misstated unrecognized gains or losses.
- Related Party Activities: Cash movements between related parties or affiliated entities, which are higher risk transactions due to potential conflicts of interest, lack of transparency, or non-arm’s length terms.
Industry-Specific Considerations
- Retail: While issues like sales tax misclassification and unrecorded deposits are common across industries, they are especially prevalent in retail due to high transaction volume, decentralized cash handling and varying point-of-sale systems. These operational factors can obscure irregularities, increasing the value of routine proof of cash procedures.
- Manufacturing: Manufacturers may encounter typical reconciliation issues such as timing differences and foreign currency impacts, but their large volume of supplier payments and complex procurement cycles elevate the risk of errors or delayed disbursements. Proof of cash can help verify that significant cash outflows are properly aligned with production activity.
- Financial Services: Given the high frequency of client transactions within and/or related to fiduciary accounts, fee deductions and inter-account transfers, this sector faces an increased risk of misclassification and incomplete recording. Proof of cash is particularly effective in distinguishing client activity from firm operating cash, reducing the risk of misstatements.
- Healthcare: Healthcare providers frequently deal with fragmented payments from insurers, patients and government programs. While unrecorded income is a broad issue, it is especially complex in this context due to partial payments, claim disputes and payment rejections. Proof of cash helps assess that cash inflows are fully captured and appropriately classified.
Relevance in the Context of Audited Financials
Audits are not all created equal, and the scope, depth and rigor of audit procedures can vary significantly depending on the auditor’s methodology, the engagement terms and the jurisdiction. Few audits include a proof of cash procedure and will place more emphasis on the control environment. Further, audits are balance sheet focused and test the accuracy of those accounts as of one specific date. Due diligence typically focuses on the income statement and will virtually always include some period that is not audited. As such, relying solely on audited statements without performing a proof of cash can leave material gaps in financial due diligence. It is important to note that a proof of cash reconciliation adds an essential layer of complementary analysis:
- Enhanced Accuracy: While financial audits provide a comprehensive review of a target's financial statements, proof of cash reconciliation offers a detailed examination of cash transactions. This process ensures that cash inflow and outflow is accurately recorded.
- Detecting Subtle Discrepancies: Audits typically focus on overall financial health and compliance as of the audit date and subject to materiality thresholds, but a proof of cash reconciliation digs deeper into individual transactions. This can uncover discrepancies missed during an audit, such as timing differences, unrecorded deposits or misclassified expenses.
- Fraud Detection: By comparing recorded transactions with actual cash movements, it is possible that a proof of cash could reveal unauthorized transactions, misappropriation of funds and other irregularities that might not be evident in a standard audit. It is important to note that proof of cash is not designed to, nor should it be relied upon, to detect fraud.
Proof of cash reconciliation is a vital procedure in financial due diligence. It assesses the completeness and reliability of financial statements, could detect discrepancies early and reinforces stakeholder confidence. As transactions grow in complexity, integrating proof of cash reconciliations into diligence procedures offers meaningful insight.
Despite its value, the proof of cash remains an underutilized tool in many M&A transactions. Given its ability to potentially uncover hidden risks and assess the completeness of the reported financials, it should be considered a standard component of every due diligence process. Its absence can leave critical blind spots, especially in cash-intensive or operationally complex businesses.
Moreover, the inability to complete proof of cash reconciliation, whether due to missing records, inconsistent bank data or poor internal controls, should be viewed as a significant red flag and the risk profile of the transaction increases substantially.
