audit risk model

If any errors are caught during the testing, the auditor requests that management propose correcting journal entries. Auditors can also provide their opinions to business owners about the information listed on the income statement. Audit risk model is used by the auditors to manage the overall risk of an audit engagement.

It would be impossible to check all of these transactions, and no one would be prepared to pay for the auditors to do so, hence the importance of the risk‑based approach toward auditing. Auditors should direct audit work to the key risks (sometimes also described as significant risks), where it is more likely that errors in transactions and balances will lead to a material misstatement in the financial statements. It would be inefficient to address insignificant risks in a high level of detail, and whether a risk is classified as a key risk or not is a matter of judgment for the auditor.


For example, if during an audit process, the auditors realize that the risk of material misstatement is high, they need to reduce the detection risk in order to ensure that the total audit risk is under an acceptable level. When performing the audit work, auditors usually follow a risk-based approach. In this approach, auditors analyze and assess the risks related to the client’s business, transactions and internal control system in place which could lead to misstatements in the financial statements.

Different industries might face different challenges in financial reporting. Auditors hold a lot of responsibility when providing their professional audit opinion on a report. Given the different types of audit risk that exists, an audit risk model can be useful in determining the likelihood of submitting an incorrect report. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. An auditor’s report is a written letter attached to a company’s financial statements that expresses its opinion on a company’s compliance with standard accounting practices.

The Essence of Audits in Today’s Business Environment

While it’s impossible to fully remove every type of risk that exists, auditors can use the audit risk model to better manage risk to an acceptable level. Detection risk is the risk that an auditor fails to identify a material misstatement. This means that the organisation may have evidence of fraud or mistakes, but the auditor doesn’t take notice. Even if the auditor misses this critical fact unintentionally, they will still be considered to be at fault. That being said, detection risk is present even if an auditor is very thorough in their audit process.

Detection risk can be reduced by auditors by increasing the number of sampled transactions for detailed testing. The reason as to why these risks are multiplied and not added is simply because of the reason that in the case where one of these risks exists, it tends to have an exponential impact on the overall audit risk. If one risk exists, it tends to amplify the overall audit risk by a factor of more than 1. Therefore, these risks are multiplied in order to get the underlying audit risk. Sometimes, that nature of business could link to the complexity of financial transactions and require high involvement with judgment. Inherent risk arises due to susceptibility of an item to misstatement due to its nature.

Audit risk model definition

The statement of cash flows is a great indicator of a company’s financial state. The cash flow statement is the last financial statement analyzed for an audit. The auditor’s letter follows a standard format, as established by generally accepted auditing standards (GAAS). Inherent risk is based on factors that ultimately affect many accounts or are peculiar to a specific assertion. For example, the inherent risk could potentially be higher for the valuation assertion related to accounts or GAAP estimates that involve the best judgment.

At this stage, the auditor might understand the client nature of the business, major internal control over financial reporting, financial reporting system, and many more. The auditor should also assess audit risks at the time they prepare the audit plan. Normally, this is done audit risk model by using a control framework like COSO to assess all angles of the business process. Detection risk is the risk that the auditor fails to detect the material misstatement in the financial statements and then issued an incorrect opinion to the audited financial statements.

Footnotes (AS 1101 – Audit Risk):

If inherent risk and control risk are assumed to be 60% each, detection risk has to be set at 27.8% in order to prevent the overall audit risk from exceeding 10%. Detection Risk is the risk that the auditors fail to detect a material misstatement in the financial statements. Given these risk levels, the auditor needs to plan his substantive audit tests to reduce the risk of not detecting material misstatements to 9%.
