Part 1: Audit planning and risk of audit 1. What is a statutory audit? a. **Audit that is obligatory** b. The audit of the consolidated annual financial statement of a group of companies i. banks, insurance companies ii. cooperative savings and credit unions iii. entities trading securities and provisions on investment funds 2. Present the definition of audit risk c. The risk that an auditor may issue an inappropriate opinion on financial statements that are materially misstated. d. The risk that the auditor iv. will issue an unmodified opinion even though the FS contains a material misstatement or omission; v. will issue a modified opinion even though the FSs are properly summarized in all material aspects. 3. What kind of audit risk can we describe or mention and what is the difference between them ----------- --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- ------------------------------------------------------------------------------------------------------------- Risk type Definition What differentiates it Inherent The risk that there is a material misstatement due to the nature of the industry - eg. some misstatements happen often due to many complex transactions - **assuming no internal controls** **Unrelated** to the internal control system or the auditor's work - some misstatements are bound to happen Control The risk that the internal control won't prevent or detect material misstatements because it's not effective enough Related to the effectiveness of **internal control system** Detection The risk that audit procedures will not detect a material misstatement. Related to the effectiveness of the **auditor's work** ----------- --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- ------------------------------------------------------------------------------------------------------------- 4. Present the difference between final and interim or begin audit e. Interim vi. Done during the financial year vii. To understand company viii. To do tests of control ix. Preliminary testing to reduce the workload during the final audit f. Final x. Done after the financial year-end xi. Verifying financial statements to check if there are no material misstatements xii. Considering assertions in fs to e.g., check for completeness, accuracy 5. What factors to consider by an external auditor when an external auditor wants to use the work of an internal audit g. Competence of Internal Auditors: xiii. The internal audit function must have adequate skills, experience, and knowledge to perform its work effectively. xiv. This includes: 1. Qualifications and training of internal auditors. 2. Appropriate supervision of internal audit activities. h. Objectivity: xv. Evaluate the internal audit\'s independence from management. xvi. Factors that support objectivity include: 3. Internal audit\'s organizational status (e.g., reporting directly to the board or audit committee). 4. Policies that protect internal auditors from managerial interference. 5. Independence of internal auditors from the areas they audit. i. Systematic and Disciplined Approach: xvii. The internal audit function must follow a structured methodology, including: 6. Clear documentation of processes and work. 7. Adequate quality control procedures, such as reviews of internal audit work. j. Scope of Work: xviii. Determine whether and to what extent the internal audit work can be used. k. Communication and Coordination: xix. Use direct assistance from internal auditors during the audit. xx. Appropriately direct, supervise, and review the work of internal auditors if used for direct assistance. 6. Mention the difference between internal and external audit -------------- ------------------------------------------------------------- ------------------------------------------------------- Internal External Purpose Check internal controls, risk management, and governance Form an independent opinion on the fairness of the FS Reporting To the management To the shareholders Scope Border, large scope Narrower scope - mainly focused on FS Independence Lower - can be influenced by management Greater - independent of the audited company Works Continuously Once a year Auditors Usually employees of the company but can also be outsourced From an external and independent company -------------- ------------------------------------------------------------- ------------------------------------------------------- 7. Define materiality l. It is the impact of a misstatement m. The auditor needs to assess xxi. If the misstatement affects the economic decisions of users 8. Eg overstating profits to attract investors when materiality is significant xxii. What is the size and nature of misstatements xxiii. What are the information needs of the users as a group n. The determination of materiality is a matter of professional judgment xxiv. Is subjective o. Applied when planning and conducting the audit 8. Present the difference between executive and trivial materiality ------------- --------------------------------------------------------------------------------------- --------------------------------------------------------------------------------------------------------------------------------------------------------- ---------------------------------- Materiality Definition Purpose Threshold Executive The overall materiality level for FS as a whole If the threshold is exceeded, the misstatements are material Highest Performance To reduce the probability of undetected misstatements to an appropriately low level To detect misstatements before it's not too late - before they reach executive materiality level or become large enough to influence economic decisions Lower than executive - 60-85% Trivial To check if the misstatements can be ignored due to being too small to have an impact If the threshold is not exceeded, the misstatements are irrelevant Lowest - up to 5% of materiality ------------- --------------------------------------------------------------------------------------- --------------------------------------------------------------------------------------------------------------------------------------------------------- ---------------------------------- 9. What is the difference between reasonable and limited assurance? +-----------------------+-----------------------+-----------------------+ | | Reasonable | Limited | +-----------------------+-----------------------+-----------------------+ | Level | High level of | Moderate level of | | | assurance (not | assurance, lower than | | | absolute) that FS has | reasonable that FS | | | no misstatements | has no misstatements | +-----------------------+-----------------------+-----------------------+ | Procedures | Extensive and | Less extensive: | | | detailed: | | | | | - Inquiry | | | - Inspection | | | | | - Analytical review | | | - Observation | | | | | | | | - Analytical | | | | procedures | | +-----------------------+-----------------------+-----------------------+ | Opinion | Positive | Negative | +-----------------------+-----------------------+-----------------------+ | Engagement risk | Reduced to the lowest | Reduced to an | | | practicable level | acceptable level but | | | | not as low as | | | | reasonable | +-----------------------+-----------------------+-----------------------+ | Scope | Broad and requires | Narrower scope | | | more time and effort | | +-----------------------+-----------------------+-----------------------+ | Purpose | Obtain evidence to | Identify material | | | form an opinion | misstatements or | | | | non-compliance | +-----------------------+-----------------------+-----------------------+ | Examples | - FS audit | - Review of interim | | | | FS | | | - Compliance audit | | | | | - For non-financial | | | | reporting | +-----------------------+-----------------------+-----------------------+ 10.
