PART 2 Self Review Flashcards
When to use Attribute Sampling?
“Appropriate for Discrete Variables
Used for Test of Controls (usually test compliance/ noncompliance)”
When to use Variable Sampling?
“Appropriate for Continuous Variables
Used for Substantive Testing (values, amounts, weights, accounts)”
What is the objective of Stop-or-go Sampling?
To reduce the sample size when the auditor believes the deviation rate in the population is low
Stop: deviation rate is BELOW a specified rate at a specified level of confidence
Go: deviation rate EXCEEDS specified rate
What is the objective of mean per unit sampling?
“Increasing audit efficiency by separating the population into logical groups, usually by various ranges of the tested amounts.
By creating multiple populations, the variability within each is reduced, allowing for a smaller overall sample size”
When is Ratio Estimation preferable to Difference Estimation?
When differences between the audited amounts of sample items and their recorded amounts are expected to vary in proportion to the size of the sample items.
When is Ratio Estimation preferable to MPU Estimation?
The standard deviation of the sample item amounts is greater than the standard deviation of the distribution of the ratios of the audited amounts of sample items compared to their recorded amounts
When is Monetary-unit Sampling Used?
“MUS is appropriate for testing account balances for overstatement when some items may be far larger than others in the population. In effect, it stratifies the population because the larger account balances have a greater chance of being selected.
MUS is most useful if few misstatements are expected”
How are test data used?
“Auditor observes how the system processes good and bad dummy data.
Test data must never mingle with real data”
What is an example of limitations of GAS?
“It it can only be used on hardware with compatible operating systems. “
How are integrated test Facilities used?
” The auditor creates a fictitious entity (a department, vendor, employee, or product) on the client’s live production system.
All transactions associated with the dummy entity are processed by the live system, and the auditor can observe the results.”
What is Tracing?
“Tracing follows a transaction forward from the triggering event to a resulting event, ensuring that the transaction was accounted for properly.
Tests the COMPLETENESS assertion”
What is Vouching?
“Vouching tracks a result backward to the originating event, ensuring that a recorded amount is properly supported. (in some cases, vouching is also referred to as tracing, auditor must note the relationship of the documentary evidence, not just the terms)
From Accounts/ Ledgers to Source Document
Tests the EXISTENCE assertion”
What are the qualities of communication?
“1. Accurate
- Objective
- Clear
- Concise
- Constructive
- Complete
- Timely”
What are the four attributes of Observations and Recommendations?
“1. Criteria
- Condition
- Cause
- Effect”
What are the levels of a Maturity Model
“1. Initial
- Repeatable
- Defined
- Managed
- Optimizing”
What are the different types of Benchmarking
“1. Competitive
- Process (function)
- Strategic
- Internal
- Generic”
What are the matters to consider prior to preparation of engagement work programs
“1) Engagement scope
2) Means of achieving objectives
3) A risk and control matrix
4) Availability of essential resources
5) Sample sizes
6) Conclusions and judgments during planning”
What are the four formats of CSA Facilitation Approach?
“1) Objective-Based- to decide whether the control procedures are
working effectively
2) Risk-Based-to determine significant residual risks
3) Control-Based- to produce an analysis of the gap between how
controls
4) Process-Based- aims to evaluate, update, validate, improve, and even streamline the whole process”
What are the four types of interviews
“1. Preliminary
- Fact-gathering
- Follow-up
- Exit “
What is a confidence interval (Precision)
Is the range around a sample value that is expected to contain the true population value.
Nature of Work of Internal Audit
The internal audit activity must evaluate and contribute to the improvement of the organization’s GRC processes using a systematic, disciplined, and risk-based approach.
Internal audit credibility and value are enhanced when auditors are proactive and their evaluations offer new insights and consider future impact.
