Test Of Control

Test of control, also known as control testing, is a process that assesses and audit the effectiveness of a company's internal controls in detecting misrepresentations or errors in financial statements and procedures. Seeing such issues is crucial in preventing and addressing operational and legal concerns arising from mismanagement.

By evaluating a company's internal controls, control testing provides an additional level of assurance to the detection system, effectively bolstering its reliability. Accurate and reliable information is essential for businesses to make informed decisions. While a financial audit is mandatory, control testing further strengthens the overall system, making it more robust and trustworthy.

• The test of control definition involves reviewing and verifying the effectiveness and dependability of a company's financial control systems, designed to detect errors or mistakes in financial statements, transactions, accounts, and other financial information.
• Auditors conduct the control testing regularly to ensure the precision and reliability of the financial information utilized and communicated by the company to external parties.
• Control testing encompasses two types: a concurrent test and a planned test, chosen by the auditor based on the mode and frequency of testing deemed appropriate for the specific audit engagement.

The test of control in audit is a recurring process within a business firm. As a company's finances are susceptible to mistakes and potential misrepresentations, ensuring error-free financial information is paramount from both operational and legal standpoints.

Errors in financial data can lead to adverse outcomes. Firstly, incorrect data in operations might impede the company's ability to achieve its objectives. Secondly, the company may be held accountable if regulatory authorities detect errors, leading to legal consequences.

Companies employ various tools to detect and prevent such errors, with an increasing emphasis on computers and artificial intelligence for error detection. However, despite these efforts, certain discrepancies may still need to be noticed. Consequently, it becomes crucial to test the effectiveness of the testing system itself.

There are two types of tests of control: concurrent and planned. The accompanying test assesses users' understanding of the control systems and is considered reliable if they demonstrate a good grasp of them. To ascertain their reliability, the auditor examines control system policies' proper and consistent application in planned tests.

Control testing involves four essential steps: inquiry, observation, reperformance, and inspection.

Stage #1 – Inquiry

Inquiry represents the initial and fundamental step in control testing. During this stage, the auditor poses specific questions to employees regarding the company's financial statements, internal control procedures, and related matters.

Stage #2 – Observation

In this stage, the auditor actively observes the company's operations in real-time to understand its business processes, focusing on the effectiveness of control procedures. It enables the auditor to identify the control systems' efficiency and potential associated issues.

Stage #3 – Reperformance

Reperformance is a critical audit sampling method in which the auditor replicates the actions of the control system to gather evidence supporting the effectiveness of the testing procedure.

Stage #4 – Inspection

Auditors carefully examine business documents, such as records, invoices, and receipts, seeking signs of review, such as signatures, stamps, or other approval indicators. These documents are selected randomly and thoroughly verified.

It is essential to emphasize that these procedures are not isolated one-time activities but are conducted regularly as part of the control testing process. When errors are discovered, appropriate measures should be taken to control and resolve them promptly.

Let's study a few examples of control testing.

Example #1

XYZ is a supplier of raw materials. Inventory management and accounting is an essential part of their business. Inventory is an asset and a source of cash flow. They use many methods to tally their inventory and detect shrinkages, theft, etc., such as physical counting, spot checking, and inventory management software. However, the auditor tests the reliability of these methods every year.

Example #2

United States regulators gained 'good access' to reviewing audit work conducted in New York-listed Chinese companies. Control testing was done during a seven-week inspection to resolve the bilateral issues between the two countries. However, Chinese authorities have been skeptical about allowing overseas regulator inspections citing national security concerns.

E-commerce company Alibaba and fast-food restaurant chain Yum China Holdings are among the companies that underwent inspection. The testing is expected to take several months as the accounting methodology and quality control have to be examined.

Substantive procedures and tests of details and control are often used interchangeably in auditing. Nevertheless, these are similar but different. Let us understand the distinctions between them.

1. Control testing verifies the reliability of testing systems that detect errors or discrepancies in financial records. Substantive procedures identify errors or discrepancies in financial statements or accounting procedures. In contrast, the test of details examines details (data, numbers, accounts, etc.) to verify accuracy and detect errors.
2. Control testing evaluates the effectiveness of the testing system itself. Substantive procedures include analytical testing (comparing expected trends to actual ones), and the test of details involves tracing back to the source information and reconciling data.

The objective of all three is the same – make financial information more accurate and reliable, and detect misrepresentations or mistakes.
