Chapter 9 Flashcards
CAS 315 requires all five components of _____ internal control to be addressed and understood
COSO framework
what are the five components of COSO?
- control environment
- risk assessment
- control activities
- information and communication
- monitoring
auditor uses his understanding of COSO to
identify potential errors or fraud and other irregularities that can increase risk material misstatement
the risk of material misstatement must be monitored at both
overall financial statement level and assertion level
once potential errors or fraud risks are identified
use to design the audit procedure to respond to the risks
items to understand information system and communication (7)
- financial reporting process (accounting estimates and disclosures)
- nature and details of procedures
- controls surrounding journal entries
- major classes of transactions of entity
- how transactions initiate and recorded
- accounting records exist and nature
- how information system get other events significant to fin. statements
methods to document understanding of control activities (3)
- narrative
- flowchart
- internal control questionnaire
def: narrative
written description of internal controls
what elements are included in narrative (4)
- origin
- processing
- disposition of documents and records
- relevant control activities
def: flowchart
diagrammatic representation of client’s documents and records and sequence in which processed
def: internal control questionnaire
series of questions about controls in each audit area
if questions in questionnaire are answered no?
failure of internal control so completeness objective not completed
how to evaluate if controls have been implemented
- consider if the control when in operation would achieve this objective
- is the control implemented
- is it carried out by appropriately qualified persons
methods to evaluate implementation of controls (6)
- previous experience with entity
- make inquiries of client personnel
- examine doc and records
- observe activities and operations
- walk through of accounting system or transaction
- assess control risk
before making preliminary assessment of control risk for each class of transactions
must see if entity is auditable
3 criteria for auditable entity
- management lacks integrity
- accounting records are deficient (lack evidence)
- complex IT environments (must have skills)
how to assess control risk at assertion level
control risk matrix
Def: control risk matrix
method used to help auditor assess control risk by matching key internal controls and internal control weaknesses with transaction related audit objectives
purpose of control risk matrix
provide a convenient way of organizing control risk for each assertion and related audit objective
process of assessing control risk with matrix
- identify audit objectives (assertions)
- identify specific relevant controls
- associate controls with objective (assertion)
- identify and evaluate control deficiencies, significant deficiencies and material weaknesses
a C in control matrix means
affects the objective listed at the top
a D in control matrix means
deficiency
