9 - II: Internal control Flashcards
How should the auditor obtain an initial understanding of internal control?
Through inquiry of appropriate personnel, observation, review of audit documentation.
What is transaction cycle? Examples?
A group of essentially same type of transactions.
Revenue/receipts, expenditures/disbursement, payroll..
How is the transaction cycle related to audits?
Control risk is constant within the transaction cycle. It’s the highest level of aggregation about which meaningful generalizations of control risk can be made.
What are 3 basic ways to document the understanding of internal control?
- Flowcharts.
- Internal control questionnaires (ICQs).
- Narrative write-up (written memo).
What are advantages and disadvantages of flowcharts? Meaning of specific symbols?
A systematic approach that prevents overlook important considerations, fairly easy to review/understand/update. Tailored to client specific.
Tedious/time consuming. Might miss deficiencies by too much details.
Square: computer operation/process. Square w/wave bottom: document. Square with narrowed bottom: manual operation (off-line). Diamond: decision point. Triangle point down: Off-line storage (filing).
What are advantages and disadvantages of ICQs?
Can be prepared in advance - prevent missing important questions. No answer indicates deficiency - easy.
Generic questionnaires not tailored to client - irrelevant questions can be included. Client could inaccurately answer intentionally/unintentionally.
What are advantages and disadvantages of narrative write-ups?
can be tailored to client. can be as detailed or general. easy to prepare.
Relatively easy to overlook important considerations because analysis is fairly unstructured.
What is walkthrough?
The auditor takes a few transactions to trace them through the client’s accounting system to get some feedback as to whether the auditor has accurately understood/documented the way the client is processing transactions.
Is walkthrough evidence or test of controls?
No.
What is a type of control: compensating?
Supplements a basic underlying control.
What is a type of control: preventive?
Prevents erros or fraud from occurring.
What is batch processing?
Transactions that are processed by type.
What is the purpose of obtaining sufficient knowledge of an entity’s information system?
To understand the financial reporting process used to prepare the entity’s F/S, including significant accounting estimates/disclosures.
What are 4 steps of evaluating internal control?
- Preliminary evaluation of internal control.
- Perform test of controls.
- Reevaluate planned reliance based on the results of test of controls.
- Develop a detailed audit plan.
What is the first stage of preliminary evaluation?
Consider whether reliance on certain specific internal control strength is appropriate. Consider the apparent adequacy of controls regarding design effectiveness.
What should the auditor do if internal control is perceived to be ineffective?
Assess the control risk at the maximum level (no reliance) and perform a wholly substantive audit approach by;
- considering the possible types of errors/problems that could occur.
- considering the kinds of procedures that would prevent/detect those.
- determine whether such control is in place.
- evaluate implications of any identified weaknesses.
If internal control is perceived effective?
Perform tests of control to evaluate the operating effectiveness of control. Consider cost-benefit issues.
What is the purpose of test of controls?
To verify the controls that looked good on paper (design effectiveness) were actually working as intended through the period (operating effectiveness).
What is the purpose of considering internal control?
To design an audit plan to achieve an appropriate level of detection risk.
Who is responsible for internal control?
Management.
What are 3 basic inherent limitations of internal control?
- Cost-benefit considerations.
- Mistakes due to misunderstanding, misjudgments, carelessness, fatigue, etc.
- Segregation of duty may break down due to collusion (a conspiracy among employees/management to circumvent internal controls) or management override.
At the very beginning stage of initial review of I/C, if I/C is not adequate to audit, what must the auditor do?
Disclaim an opinion or withdraw from the audit.
When the auditor determines that I/C effective, but cost > benefit, what should he do?
No reliance. Perform a wholly substantive audit approach.
When is test of control required?
When the auditor relies on the control or substantive tests alone are not sufficient to audit particular assertions.
What must the auditor obtain knowledge about when understanding an entity’s I/C?
Design controls.
How is test of control performed?
Select a sample of transactions and verify that the control procedures of interest were performed.
Control risk should be assessed in terms of what?
F/S assertions.
AICPA: what are 2 responsibilities of the auditor?
- Understanding the entity and its environment and assessing the risks of material misstatement.
- Performing Audit Procedures in response to assessed risks and evaluating the audit evidence obtained.
AICPA: What are 3 key objectives of I/C?
- Reliability of financial reporting.
- Effectiveness and efficiency of operations.
- Compliance with applicable laws and regulations.
