The engagement partner agreed with Sessions's recommended approach. In planning the zaudit evidence for detailed inventory tests, the audit risk model was applied with the following results (5 Marks): AAR TDR = IR X CR X APR where: TDR = test of details risk AAR = acceptable audit risk IR = inherent risk CR = control risk APR = analytical procedures risk Therefore, using Sessions's assessments and judgments as described previously, .05 TDR = 1.0 X.5 X.6 TDR = 0.17 I= sired a. Explain what . 17 means in this audit (1 Mark). b. Calculate TDR assuming that Sessions had assessed control risk at 100% and all other risks as they are stated (2 Marks). c. Explain the effect of your answer in requirement b. on the planned audit procedures and sample size in the audit of inventory compared with the 0.17 calculated by Sessions (2
