5. Entity ’ s risk assessment process Identifying BR relevant to financial reporting objectives Estimating the significance of the risk Assessing the likelihood of their occurrence Deciding upon actions to address those risks

Determine the time period in which transactions occurred to permit recording of transactions in the proper accounting period. Present properly the transactions and related disclosures in the financial statements.

9. Monitoring of controls Internal audit function

18. Evaluating the IC system –CR Assess whether controls exist (Weak IC) a. No controls CR = Max a. No controls CR = Max b. Not cost-effectiveCR = Max b. Not cost-effective CR = Max Extensive substantive test Assess whether controls exist (Weak IC) a. No controls CR = Max a. No controls CR = Max b. Not cost-effectiveCR = Max b. Not cost-effective CR = Max Extensive substantive test Yes ?

19. Evaluating the IC sys Yes, controls exist (Strong IC) 1.Perform tests of controls 2.Revise CR 3. Reduced substantive test Yes, controls exist (Strong IC) 1.Perform tests of controls 2.Revise CR 3. Reduced substantive test

20. Auditing in a CIS environment The overall objective of an audit in a CIS environment does not change The CIS is likely to have an effect on IR and CR. The use of IT affect the way that control activities are implemented The auditor should consider whether specialized skill are needed in the audit (use the work of an expert)

21. Classification of controls General controls Application controls --programmed controls --manual controls

22. general control Programmed application control Manual application control Transactions Relate to all computer application Relate to specific computer application

23. General controls — ISA 315 Policies and procedures that relate to many applications and support the effective functioning of application controls by helping to ensure the continued proper operation of information system. -- data center and net work operation -- sys software acquisition, change and maintenance -- access security (operational control) -- Application sys acquisition, development and maintenance

24. Application control Manual or automated procedures that typically operate at a business process level Designed to ensure the integrity of the accounting records Relate to specific control procedures used to initiate, record, process and report transaction or other financial data. Ensure transactions occurred are authorized, completely and accurately recorded and processed timely

25. Application controls Control over input Control over processing Controls over output Master file control

26. Further examples of selected controls Manual controlsManual controls -- physical controls -- back-up disks -- data filing -- documentation --staff training --proofing Programmed controlsProgrammed controls -- passwords -- date/time stamps -- prompts --check digits -- Batch totals and hash totals -- Reasonableness checks -- Existence checks -- Dependency checks
