Materiality and Audit risk
3.1.3 Fundamental Concepts
in Auditing
Trang 21Fraud and Error
A Student took materials (text books or mini photocopies) in
examination room (Rule: Close-book exam)
Is it a fraud and an error?
Trang 22What is Fraud?
As a broad legal concept, fraud describes any intentional deceit
meant to deprive another person or party of their property or rights.
In the context of auditing financial statements, fraud is defined
as an intentional misstatement of financial statements.
Trang 23Types of Fraud
Misappropriation of assets
Fraudulent Financial Reporting
Trang 24Misappropriation of assets (“employee fraud”) involves theft of an
entity’s asset.
Examples include:
Embezzling receipts
Stealing physical assets or intellectual property
Assets are used with wrong purposes
….
Trang 25Fraudulent Financial Reporting (“management fraud”)
Earnings management
Income smoothing
Inadequate disclosure
….
Trang 27What is Error?
Unintentional mistakes in financial information such as:
Errors of commission: mathematical or clerical mistakes
in the recording and accounting data;
Errors of omission: transactions, events is left out of an
accounting statement by mistake
Errors of principle: misapplication or misunderstanding of
accounting policies unintentionally Ex: wrong allocation between different accounts, wrong valuation of assets,…
Trang 28Causes of accounting errors
Time pressure in the process of recording accounting
transaction
Pressure of working environment
Working style of accountants : Careless or negligent,
distract,
Limited qualification of accountants
Trang 29Materiality is the magnitude of an omission or
misstatement of accounting information that, in the light of
surrounding circumstances, make it probable that the judgment
of a reasonable person relying on the information would have been changed or influenced by the omission or misstatement
Source: Financial Accounting Standards Board (FASB)
Trang 30Assessment of Materiality
Materiality is a relative rather than absolute concept
Materiality includes both quantitative and qualitative consideration (size and nature of the misstatement)
Trang 31 Quantitative materiality level
No official guidelines within auditing standards
Bases for evaluating Materiality
5-10% of Net Income before Taxes
Trang 32 Qualitative Considerations
Amount involve fraud are usually more important than
unintentional errors of equal dollar amounts => reflect on honest and reliability of management
Misstatements that are otherwise minor may be material if there are consequences influenced related significant
accounts
Misstatements that are otherwise immaterial if they affect
Trang 33Study Break
1 Which is the following statements is not correct about materiality:
A.The concept of materiality recognizes that some matters are important for fair presentation of FS in conformity with GAAP, whereas other matters are not important.
B.An auditor considers materiality for planning purpose in term of
largest aggregate level of misstatements that could be material to any one of the FS
C.Materiality judgments are made in light of surrounding circumstances and necessarily involve both quantitative and qualitative judgments
D.An auditor’s consideration of materiality is influenced by the auditor’s perception of needs of reasonable person who will rely on the FS
Trang 34Study Break
2 Any amount of misstatement that is less than the level of materiality
would be referred to as:
A Quantitative misstatement
B Material misstatement
C Immaterial misstatement
D Probable misstatement
Trang 35Audit Risk
Audit risk means the risk that the auditor gives an inappropriate audit opinion when the financial statements are materially
misstated (ISA 400)
It’s not practical totally eliminate audit risk => minimize the risk
to extent possible (accepted audit risk)
Trang 36Accepted audit risk
Accepted audit risk is a measure of how willing the auditor is
to accept that the financial statements may be materially
misstated after the audit is completed and an inappropriate opinion has been issued
For many audit firms, accepted audit risk is 5% or lower (1%
or ½%,…)
Trang 37Accepted audit risk
AAR = 5%??????????????
Same as audit assurance = 95%
Trang 38Audit Risk Model
= Inherent Control Detection
Risk * Risk * Risk
Trang 39Inherent Risk
Inherent risk is the susceptibility of an account balance or class of transactions to misstatements that could be material, individually or when aggregated with misstatements in
other balances or classes, assuming that there are no related internal control (ISA 400)
Trang 40Control Risk
Risk that a material misstatement, that could occur in an
account balance or classic of transaction and that could be
material individually or when aggregated with misstatements
in other balances or classes, will not be prevented or detected
on a timely basis by the company’s internal control (ISA 400)
OR Risk that controls do not prevent or detect fraud / errors
Auditors assess CR through evaluating the effectiveness of internal control system
Trang 41Detection Risk
Risk that an auditors’ substantive procedures will not
detect a material misstatement that exist in an account
balance or class of transaction, individually or when
aggregated with misstatements in other balances or classes (ISA 400)
OR Risk that auditor’s procedures do not detect material
fraud / errors

Trang 43Interrelationship of the components of audit risk
Trang 44AUDIT EVIDENCE
Any information used by the auditor for
determining whether the information being
audited is stated in accordance with
established criteria
Trang 45Audit Evidence (AE)
AE is the information obtained by the auditor in arriving at the conclusions on which the audit opinion is based
AE is the documentations and information which is
obtained by the auditor in connection with audit on which the audit opinion is based (ISA 500 para 04)
AE includes source documents and accounting records

evidence is being gathered:
1 Sending a written request to the client’s customers requesting that they
report the amoung owned to the client.

Types of Audit
tests in Financial
Audit
Trang 78Types of Audit Tests
Trang 79Tests of control
An auditor performs tests of control to obtain evidence about whether the control activities of the internal control system are effective
The tests are designed to provide evidence to support an
assessment of control risk at a level below high (indicating
reliance on the keys controls)
Trang 80Substantive tests
Performed on specific transactions and balances to see
whether the dollar amount of an account balance is materially misstated
These tests reduce detection risk
Trang 81Types of substantive tests
Analytical procedures: involve the study and comparison of
relationships between accounting data and related information
Tests of details: obtaining evidence on the items (or details)
included in an account balance or class of transactions:
Substantive tests of transactions (used to determine whether
all six transaction related audit objectives have been
satisfied for each class of transactions)
Tests of details of balances (focus on the ending general
ledger balances for both balance sheet and income statement accounts)

Internal Control
Trang 83Five Components of Internal
Control
Trang 84Control environment
Includes governance and management’s overall attitude,
awareness and actions regarding IC and its importance in the
entity (ASA/ISA 315.A65)
Auditors should consider:
Communication and enforcement of integrity and ethical values
Commitment to competence
Participation by those charged with governance
Management’s philosophy and operating style
Organisational structure
Assignment of authority and responsibility
Human resource policies and practices.
Trang 85Entity’s risk assessment process
Entity’s way of identifying and responding to business risks
Once risks are identified, management needs to consider their significance and how they should be managed
Management may introduce plans to address specific risks or it may accept a risk on a cost-benefit basis
Trang 86Information system
An effective information system establishes the records and the methods that:
Identify and record all valid transactions
Resolve incorrect processing of transactions
Process and account for system overrides
Transfer information from transaction processing
systems to the general ledger
Capture information relevant to financial reporting for
events and conditions other than transactions; and
Present the transactions and related disclosures properly
