ISA (UK) 330: The Auditor’s Responses To Assessed Risks

 The auditor's goal is to collect enough suitable audit evidence to support the evaluated risks of material misstatement, as well as to create and implement effective solutions to such risks. The auditor is responsible for developing and implementing overall remedies to the risks of substantial misstatement in the financial statements.

Test of controls as defined by ISA (UK) 330 – An audit procedure designed to evaluate the operating effectiveness of controls in preventing, or detecting and correcting, material misstatements at the assertion level.

Examining a sample of purchase orders to confirm that they have been properly authorized would be a control test. A 'yes' response indicates that the internal control requiring purchase order permission is operational, whereas a 'no' response indicates that the internal control does not appear to be operational, necessitating further audit inquiry.

 

Substantive procedure as defined by ISA (UK) 330 – An audit procedure designed to detect material misstatements at the assertion level. Substantive procedures comprise:

(i) Tests of details (of classes of transactions, account balances, and disclosures); and

(ii) Substantive analytical procedures.

According to ISA 330, the auditor must always execute substantive procedures on material items, regardless of the risk of substantial misstatement, and must design and perform substantive procedures for each material class of transactions, account balance, and disclosure. Invariably, substantive procedures will need more effort than control testing. Consider the example of a manufacturing company's purchasing system and the assertion of account balances' existence in the statement of financial position. Typical detail checks would entail receiving and examining the closing purchase ledger account balances for a sample of purchase ledger accounts with selected suppliers, as well as some physical verification of year-end balances outstanding. Typically, this entails agreeing on the closing balance figure with the supplier's statement, or even asking third-party confirmation of the amount owing from the supplier.

An effective control environment may enable the auditor to have greater confidence in internal control and the reliability of audit evidence generated internally within the entity, allowing the auditor, for example, to conduct some audit procedures at an interim date rather than at the end of the period. Deficiencies in the control environment, on the other hand, have the opposite impact; for example, an ineffective control environment may prompt the auditor to:

§  Conduct more audit processes at the end of the period rather than at an interim date;

§  Obtaining more extensive audit evidence from fundamental procedures;

§  Expanding the audit scope to include more locations.

 

Practice:

Control tests are often brief, rapid audits, whereas substantive procedures will necessitate more extensive auditing. The auditor must create and perform substantial processes for each type of transactions, account balance, and disclosure, regardless of the assessed risks of material misstatement, according to ISA 330.
