The relationship between materiality and audit risk.
When conducting an audit, auditors pay attention to materiality of information and its relationship with audit risk. In an audit, the weak and the audit risk relationship is inversely proportional to each other, the higher the materiality level audit risk as low and vice versa. To obtain reasonable assurance, the auditor should obtain sufficient appropriate audit evidence to reduce audit risk to an acceptable level is low, since it allows auditors offer appropriate conclusions as the basis for the formation of our audit opinion. Auditors must consider this relationship when determining the content, timing and extent of audit procedures appropriately. To determine the level of risk is critical and complex procedure requiring qualified as well as the auditor's judgment. In fact only some audit firms of Vietnam was built according to the estimates of materiality and risks many companies still have not developed a specific procedure. 1.5 Design program audit program audits are expected to detail the audit work to perform, time to complete and the division of labor between the auditor as well as expected on materials and information related to use and collection cross. The focus of the audit program is the necessary audit procedures performed for each item or department audited. Audit Program designed suite will bring many benefits: • Arrange a how to plan the work and manpower, ensure coordination between the auditor as well as detailed instructions for the auditors in the audit process. • It is a means to audit managers (who in charge of the audit) management, oversight audits through the identification of work to be done step. • Evidence to prove the audit procedures performed. After completion of a procedure, the auditor autograph the audit program to audit procedures just completed. 1.5.1 Process design audit programs. Audit program of most audits is designed in three parts: multiple choice task, test analysts, test the balance. The design of the test work. The audit procedures: The design of audit procedures of routine compliance tracnghiem according to the methodology of four steps: • To concretize the internal audit objectives for the survey items • Identify specific control process to reduce the risk of individual control internal control objectives . • Design control tests for each specific process control. • Design work tests for each internal control objectives considering the weakness of the internal control system and the quauoc computer controlled trials. The scale sampling: People often use attribute sampling method to estimate the proportion of elements that contain a trait or attribute is interested in the overall. Items selected: After determining the size of the sample selected, auditors must determine the choice of representative element for the overall high. In addition, if any abnormal operations or with large amounts should also be considered, although not in the form Duration: The work often have mandatory monitoring conducted in mid-year (if the audit contract LT) or the end of the year. The mid-year test is usually done to allow for an audit at the end of the financial year, in order to spread out the audit for the year. Design analysis test. The means by considering the relationship economics and trends of the economic indicators through a combination of direct projection, compare logic, balance ... the value of the index or parts that constitute the norm. The monitoring analyze test is designed to assess the reasonableness of the overall account balance is being audited. Based on the results of the performance tests that analysis, the audit will decide to expand or narrow the direct test the balance. The design of direct test balance. The design of the test Direct balances for each item on the financial statements was conducted in accordance with the following steps: First: Assessment of materiality and risk to the items being audited; Through the initial estimate of materiality and allocation estimates for each item in the financial statements, the auditor can determine the acceptable error for each item. Acceptable errors of the lower item number thidoi ask audit evidence gathered as much, and vice versa. Second: Assessment of Risk Control: Process control will effectively reduce the risk control to cycle, so the number of audit evidence to be collected in the immediate test and professional balance will decrease and vice versa. Third: Designing the direct tests to satisfy the balance the specific audit objectives of the item being considered, is designed to do the following: • The audit procedures: In the entire process of planning the audit work this section requires the occupation xetdoan offices key. • sample size shall be determined according to common sampling methods to estimate the uncertainty in the overall money being audited, from which to select the appropriate sample size. • Selected Items: After While the sample size is selected, the auditors often random sampling random number table or a computer program to determine the representative element. In some cases, may use non-determined sampling method suatde identify representative elements. • Time: Most direct test is performed on the balance at the end of period (the end of the accounting year). In fact, the audit procedures in the form of tests will be combined and rearranged according to an audit program. Audit program was designed in the early stages of the audit and can modify by changing circumstances.
