Question 1: An auditor is considering whether to accept a new audit engagement for a
manufacturing company. Which of the following procedures is most critical during the client
acceptance phase to evaluate the integrity of the client's management?
A. Performing preliminary analytical procedures on the prior year's financial statements. B.
Communicating with the predecessor auditor regarding disagreements with management. C.
Assessing the company's internal control over financial reporting for the current year. D.
Determining the preliminary judgment about materiality for the financial statements.
CORRECT ANSWER: B. Communicating with the predecessor auditor regarding disagreements
with management.
Rationale: Communicating with the predecessor auditor is a crucial step in the client
acceptance phase. The predecessor auditor can provide valuable insights into the integrity of
management, past disagreements over accounting principles, and reasons for the change in
auditors, which directly impacts the acceptance decision. Preliminary analytical procedures,
internal control assessment, and materiality determination are performed after the
engagement has been accepted, during the planning phase.
Question 2: During the planning phase of an audit, the auditor establishes materiality for the
financial statements as a whole. Which of the following factors is most appropriate to use as
a benchmark for determining this materiality?
A. The total number of employees in the organization. B. The historical cost of property, plant,
and equipment. C. Pretax income from continuing operations. D. The total cash balance at the
end of the fiscal year.
CORRECT ANSWER: C. Pretax income from continuing operations.
,Rationale: Pretax income from continuing operations is a widely accepted and appropriate
benchmark for determining materiality for the financial statements as a whole, especially for
profit-oriented entities, because it reflects the primary focus of users on the entity's
profitability. The number of employees, historical cost of assets, and total cash balance are not
representative of the overall financial performance or the primary concerns of financial
statement users.
Question 3: An auditor is evaluating the risk of material misstatement at the assertion level.
Which of the following best describes the relationship between inherent risk and control risk?
A. They are inversely related; as inherent risk increases, control risk must decrease. B. They are
components of the risk of material misstatement and can be assessed independently of each
other. C. They are combined to form detection risk, which the auditor must minimize. D. They
are determined by the auditor based on the extent of substantive testing performed.
CORRECT ANSWER: B. They are components of the risk of material misstatement and can be
assessed independently of each other.
Rationale: Inherent risk and control risk are the two components of the risk of material
misstatement at the assertion level. They exist independently of the audit and can be assessed
separately, although they may sometimes interact. They are not inversely related, they do not
form detection risk (detection risk is the risk that the auditor's procedures will fail to detect a
misstatement), and they are assessed before determining the extent of substantive testing, not
based on it.
Question 4: Which of the following procedures is considered a risk assessment procedure
rather than a substantive procedure?
A. Confirming accounts receivable balances with customers. B. Observing the client's physical
inventory count. C. Inquiring of management regarding the methodology for estimating the
allowance for doubtful accounts. D. Recalculating the depreciation expense for a sample of
fixed assets.
CORRECT ANSWER: C. Inquiring of management regarding the methodology for estimating
the allowance for doubtful accounts.
Rationale: Risk assessment procedures are performed to obtain an understanding of the entity
and its environment, including its internal control, to identify and assess the risks of material
misstatement. Inquiring of management about their estimation methodologies is a classic risk
assessment procedure. Confirming receivables, observing inventory counts, and recalculating
depreciation are substantive procedures designed to detect material misstatements at the
assertion level.
Question 5: An auditor decides to set control risk at the maximum level for a specific
assertion. What is the most likely impact of this decision on the audit plan?
,A. The auditor will perform more extensive tests of controls to verify the maximum level. B. The
auditor will decrease the extent of substantive procedures for that assertion. C. The auditor will
increase the extent of substantive procedures for that assertion. D. The auditor will issue a
qualified opinion due to the high control risk.
CORRECT ANSWER: C. The auditor will increase the extent of substantive procedures for that
assertion.
Rationale: When control risk is assessed at the maximum level, it means the auditor believes
the client's internal controls are ineffective or that it is inefficient to test them. Consequently,
the auditor must rely more heavily on substantive procedures to reduce detection risk to an
acceptably low level, thereby increasing the nature, timing, and extent of substantive testing. A
high control risk does not automatically lead to a qualified opinion if substantive procedures
can provide sufficient appropriate audit evidence.
Question 6: According to the COSO framework, which of the following is considered a
component of internal control?
A. Detection risk. B. Monitoring activities. C. Substantive analytical procedures. D. Audit
committee oversight.
CORRECT ANSWER: B. Monitoring activities.
Rationale: The COSO framework identifies five interrelated components of internal control:
Control Environment, Risk Assessment, Control Activities, Information and Communication, and
Monitoring Activities. Detection risk and substantive analytical procedures are audit concepts,
not components of the entity's internal control. While audit committee oversight is part of the
control environment, "Monitoring activities" is the specific, distinct component listed in the
COSO framework.
Question 7: An auditor is performing tests of controls over the authorization of cash
disbursements. Which of the following provides the most reliable audit evidence regarding
the operating effectiveness of this control?
A. Inquiring of the accounts payable clerk about the authorization process. B. Reading the
company's written policy on cash disbursement authorization. C. Observing the accounts
payable manager signing checks on a single day. D. Inspecting a sample of cash disbursement
vouchers for the authorized signature of the appropriate manager.
CORRECT ANSWER: D. Inspecting a sample of cash disbursement vouchers for the authorized
signature of the appropriate manager.
Rationale: Inspection of documentary evidence (such as authorized signatures on a sample of
vouchers) provides more reliable and objective evidence of operating effectiveness over a
period of time than inquiry, reading policies, or observation on a single day. Inquiry alone is
, never sufficient to test operating effectiveness, and observation is limited to the point in time it
occurs.
Question 8: Which of the following best describes the concept of performance materiality?
A. The threshold above which all misstatements must be corrected by management. B. The
amount set by the auditor at less than materiality for the financial statements as a whole to
reduce to an appropriately low level the probability that the aggregate of uncorrected and
undetected misstatements exceeds materiality. C. The maximum error rate the auditor is
willing to accept in a sample without modifying the audit opinion. D. The difference between
the expected value and the actual value of an account balance.
CORRECT ANSWER: B. The amount set by the auditor at less than materiality for the financial
statements as a whole to reduce to an appropriately low level the probability that the
aggregate of uncorrected and undetected misstatements exceeds materiality.
Rationale: Performance materiality is a buffer or haircut applied to overall materiality. It is set
at a lower amount to account for the possibility that multiple smaller, undetected or
uncorrected misstatements could aggregate to an amount that exceeds overall materiality. It is
not the threshold for mandatory correction (though all misstatements are communicated), nor
is it related to sample error rates or expected versus actual values.
Question 9: An auditor is using statistical sampling to test the operating effectiveness of a
control. If the upper deviation rate exceeds the tolerable deviation rate, what should the
auditor conclude?
A. The control is operating effectively, and no further action is required. B. The control is not
operating effectively, and the auditor should increase the assessed level of control risk. C. The
sample size was too small, and the auditor must immediately double the sample size. D. The
auditor should decrease the assessed level of control risk to compensate for the high deviation
rate.
CORRECT ANSWER: B. The control is not operating effectively, and the auditor should
increase the assessed level of control risk.
Rationale: If the upper deviation rate (the sample deviation rate plus an allowance for sampling
risk) exceeds the tolerable deviation rate, the sample does not support the planned assessed
level of control risk. The auditor must conclude that the control is not operating effectively and
should increase the assessed level of control risk, which will likely lead to an increase in
substantive testing. Doubling the sample size is not an automatic or appropriate response.
Question 10: Which of the following assertions is primarily addressed by the auditor's
procedure of tracing shipping documents to the related sales invoices and sales journal
entries?
A. Existence. B. Completeness. C. Valuation and allocation. D. Rights and obligations.
