What Is the Completeness Assertion in Accounting?

The completeness assertion is a concept in accounting, representing a declaration by a company’s management that all transactions and accounts that should be presented in the financial statements are included. It is one of several assertions that provide a framework for auditors to verify the accuracy and reliability of financial reporting.

The Role of Completeness in Financial Statements

The application of the completeness assertion is important when considering liabilities and expenses. The primary risk in this area is the understatement of these figures, which can make a company appear more profitable than it actually is. For instance, a business might receive services from a vendor in the final month of the fiscal year but fail to record the corresponding invoice. This omission understates both expenses on the income statement and accounts payable, a liability, on the balance sheet.

Another example involves debt. If a company secures a loan but does not record the liability on its books, its financial statements will not reflect the true extent of its obligations. This misrepresentation can mislead investors and creditors about the company’s leverage and risk profile.

While the risk of overstatement is often a primary concern for assets and revenues, completeness remains a relevant assertion. It ensures that all economic benefits earned or controlled by the company are reported. For example, a company might fail to record all cash sales or neglect to account for all revenue earned from a long-term project. These omissions would understate both assets and revenue, understating the company’s financial performance and value.

Auditing Procedures for Completeness

Auditors employ several procedures to test the completeness assertion. A core technique is tracing, which involves following a transaction from its source document forward to its inclusion in the financial statements. For example, an auditor might select a sample of vendor invoices or shipping documents and trace them to the accounts payable ledger and the general ledger to confirm they were recorded.

Analytical procedures are another method used to assess completeness. Auditors compare current period financial information with other relevant data to identify unusual fluctuations or deviations that might indicate unrecorded transactions. An auditor might compare the current year’s utility expenses to the prior year’s figures. A significant, unexplained decrease could suggest that some utility bills were not recorded.

Cut-off testing is a procedure focused on transactions occurring around the end of an accounting period. The objective is to ensure that transactions are recorded in the correct period. An auditor will examine receiving reports and vendor invoices for several days before and after the balance sheet date. This helps verify that liabilities for goods received before the year-end are included in the current period’s accounts payable and not improperly deferred to the next period.

To test the completeness of revenue, an auditor might trace shipping documents to sales invoices and then to the sales journal. This process helps confirm that all goods shipped to customers were billed and recorded as revenue. This ensures all earned revenues have been captured in the financial statements.

Internal Controls to Ensure Completeness

A company can implement various internal controls to build completeness into its accounting processes, reducing the risk of omissions. One effective control is the use of sequentially pre-numbered documents. Purchase orders, checks, and sales invoices are assigned consecutive numbers, and the sequence is periodically reviewed to account for every document. A gap in the number sequence can signal a missing transaction that needs to be investigated and recorded.

Regular reconciliations are another internal control for ensuring completeness. This involves comparing balances from two different sources to identify discrepancies. For example, a company’s accounting staff will reconcile the cash balance in the general ledger with the balance shown on the bank statement. This process can uncover unrecorded checks or deposits, which can then be properly accounted for.

Many companies use a matching and verification process to ensure that all liabilities are recorded. A common example is the three-way match for accounts payable. Before a vendor invoice is paid and recorded, the accounting department matches the invoice details to the corresponding purchase order and receiving report. This control confirms that the company actually ordered and received the goods or services, ensuring that a valid liability is recorded.
