Audit Sampling Case Study- Air BNB Co. You are the experienced assistant auditor for the audit of Technology Inc. (the "Company"), whose audit is subject to the standards of the AICPA. Your engagement team has identified risks of material misstatement related to the existence, valuation and allocation, and rights and obligations assertions of accounts receivable, specifically the risks of material misstatement that the client has recorded in sales and accounts receivable for sales and shipments that are not valid or are recorded at the incorrect amount. The total balance of accounts receivables is $1,118,517 rounded to $1,119,000. Your field senior has assigned you to test the accounts receivable balance by sampling and confirming balances with individual customers, which is a common audit test to address these risks of material misstatement. As part of your risk assessment procedures, you obtained an understanding of the Company's accounting policy, processes, and controls regarding the accounts receivable balance by performing procedures (including inquiries of management and process owners) and walkthroughs of the processes related to accounts receivable. As a result of these procedures, you understand that the accounts receivables balance is relatively homogeneous and consists of a high volume of low-dollar value transactions. You decide to use data analytics to obtain fact-based evidence and to corroborate your understanding of the accounts receivables balance. On the basis of your analysis, you identified one statistical outlier of $300K, while the remaining balance aggregated to $800K, which is made up of approximately 80 homogeneous transactions. Upon further inquiries about the $300K transaction above, you determined that it is a related-party transaction. On the basis of your analysis of the accounts receivable balance, you define the customer balance as the sampling unit. You determine that any balances greater than performance materiality (Tolerable misstaement) of $258K should be selected for testing and therefore select the $300K related-party transaction as a judgemental selection. You then determine that you would use PPS statistical sampling to test the remaining population. The other relevant factors are as follows: Performance materiality (Tolerable Misstatement) is $258 thousand. Clearly trivial threshold (De Minimis Materiality) is $12,906. The population size, excluding the $300 thousand selected balance, is $819 thousand (no other items are above performance materiality). The Inherent level of risk is determined to be "Higher/High." You are relying on the operating effectiveness of internal controls and therefore Control Risk is determined to be Low. Combined Risk of Inherent and Control Risk (AKA Risk of Material Misstatement "RMM") is determined to be Moderate. You determined that the "risk that other substantive procedures will fail to detect a material misstatement" is moderate. The client provided the accounts receivable population to you in electronic format. Through the use of data analytics, you noted that the population had similar, positive value characters. Q1-ii Determine what effect each factor below has on the sample size: Use table below to answer. *Put 1 letter to answer each question in the table below. Factor Effect on Sample Size (a) Increase; (b) decrease; (c) Negligible/No Effect] EX: (a) a a An increase in the assessment of the risk of material misstatement An increase in the use of other substantive procedures directed at the same assertion An increase in the desired level of Answer: assurance that tolerable misstatement is not exceeded by actual misstatement in the population An increase in tolerable misstatement An increase in the amount of misstatement expected in the population Stratification of the population when appropriate a a a
