7. 6 we are always required to obtain an understanding of the Internal Control to identify & assess the RoMM risks of material misstatement, whether due to fraud or error, at the financial statement and relevant assertion levels through understanding the entity and its environment, including the entity's internal control, thereby to provide a basis for designing and implementing responses to the assessed RoMM. planning phase

31. 30 Audit Risk Model What type of audit procedures will we perform to obtain appropriate evidence to reduce Detection Risk to a low level?

32. 31 Audit Risk Model What type of audit procedures will we perform to obtain appropriate evidence if Planned Detection Risk is high?

33. 32 What is the definition of Control Risk Chen

34. 33 Control risk. The risk that a misstatement that could occur in an assertion about a class of transaction, account balance, or disclosure and that could be material, either individually or when aggregated with other misstatements, will not be prevented, or detected and corrected, on a timely basis by the entity's internal control.

35. 34 What is the definition of Planned Detection Risk Jonathan de

36. 35 Planned Detection risk. The risk that the audit evidence for a segment will fail to detect misstatements exceeding tolerable misstatement.

37. 36 Detection risk. The risk that the procedures performed by the auditor to reduce audit risk to an acceptably low level will not detect a misstatement that exists and that could be material, either individually or when aggregated with other misstatements.

38. 37 Alyssa If we assess CR = Low, what does that tell us about the level of PDR …. ? If we assess CR = High, what does that tell us about the level of PDR …. ?

39. 38 If we assess CR = Max, what does that imply about the effectiveness of the Internal Controls? Iris

40. 39 If we assess CR = Low, what does that imply about the effectiveness of the Internal Controls? Ciara

41. 40 Katie If we assess Control Risk as Low, what type of evidence would our audit procedures need to generate?

69. 68 Given the definition of Audit Risk what is the relationship between Materiality and Audit Risk? ???

70. 69 Evaluation of Sample Results Critical Value= μ + Z β * S x /√n 2,295.47 + 1.04 *1,390.09 / √ 44= 2,513.42 We are unable to conclude that Accounts Receivable is not materially overstated because the sample mean of $2,425.56 is less than the $2,513.42 critical value.
