Inherent Risk (IR)
Definition
The probability that a material misstatement would occur in the particular audit area in the absence of any internal control policies and procedures
Audit Risk = Control Risk X Inherent Risk X Detection Risks
Inherent Risk (IR)-The probability that a material misstatement would occur in the particular audit
area in the absence of any internal control policies and procedures
. Control Risk (CR)-The probability that a material misstatement that occurred in the first place would
not be detected and corrected by internal controls that are applicable
. Detection Risk (DR)-The probability that a material misstatement that was not prevented or detected
and corrected by internal control was not detected by the auditor’s substantive audit procedures
(ie, an undetected material misstatement exists in a relevant assertion)
AICPA’s Guidance
Obtain Understanding of Entity’s Internal Controls
AU-C 315 - Auditor is to Identify and assess the risks of material mistatement.
Transaction Cycles
A group of homogeneous transactions - Ex. Revenue/receipts, Expenditures/disbursements
Adequacy of controls
The design effectiveness of controls
Procedures designed to obtain an understanding include
Control Tests - Purpose
Determine the operating effectiveness of I/C - EX. Testing a sample of invoices to determine if they were properly approved.
Sustantitive Testing: Analytical Procedures
Identify unexpected relationships between recorded amounts and other data. EX - comparing amounts of sales invoices in current year with previous year’s invoices
Substantive Testing: Tests of Details
Determine conclusively if a material mistatement has occured and by how much. Ex. Inspecting a sample of invoices to determine wheter they were properly recorded.
Analytical Procedures
Evidence gathering procedures that suggest reasonableness based upon comparison to appropriate expectations or benchmarks. THESE ARE OPTIONAL
Test of Details
Evidence gathering procedures consiting of either:
1.** Tests of ending balances **- final balance is assessed by testing the composition of the year end balance.
2. Test of tranasactions - Where the final balance is assessed by examing those debits and credits that caused the balance to change from last year’s audited balance to current year’s balance.
