Mistakes in a Monetary Unit Sampling Application. Kelsey Mead, CPA, was engaged toaudit Jiffy Company’s financial statements for the year ended August 31.For the current year, Mead decided to use MUS to select accounts receivable for confirmation because MUS uses each account in the population as a separate sampling unit.Mead expected to discover many overstatements but presumed that the MUS sample sizestill would be smaller than the corresponding sample size for classical variables sampling.Mead reasoned that the MUS sample would automatically result in a stratified samplebecause each account would have an equal chance of being selected for confirmation. Additionally, the selection of negative (credit) balances would be facilitated without specialconsiderations.Mead computed the sample size using the risk of incorrect acceptance, the total recordedbook amount of the receivables, and the number of misstated accounts allowed. Meaddivided the total recorded book amount of the receivables by the sample size to determinethe sampling interval and then calculated the standard deviation of the dollar amounts of theaccounts selected for evaluation of the receivables.Mead’s calculated sample size was 60 and the sampling interval was determined to be$10,000. However, only 58 different accounts were selected because two accounts were solarge that the sampling interval caused each of them to be selected twice. Mead proceeded tosend confirmation requests to 55 of the 58 customers. Each of the three accounts originallyselected for the sample had insignificant recorded balances under $20. Mead ignored thesethree small accounts and substituted the three largest accounts that had not been selected bythe random selection procedure. Each of these accounts had balances in excess of $7,000, soMead sent confirmation requests to these customers.The confirmation process revealed two differences. One account with an audited valueof $3,000 had been recorded at $4,000. Mead projected this to be a $1,000 misstatement.Another account with an audited value of $2,000 had been recorded at $1,900. Mead did notcount the $100 difference because the purpose of the procedure was to detect overstatements.In evaluating the sample results, Mead decided that the accounts receivable balance wasnot overstated because the projected misstatement ($1,000) was less than the allowance forsampling risk.Required:Describe each incorrect assumption, statement, and inappropriate application of sampling in Mead’s procedures.
Mistakes in a Monetary Unit Sampling Application. Kelsey Mead, CPA, was engaged to
audit Jiffy Company’s financial statements for the year ended August 31.

Mead expected to discover many overstatements but presumed that the MUS
still would be smaller than the corresponding sample size for classical variables sampling.
Mead reasoned that the MUS sample would automatically result in a stratified sample
because each account would have an equal chance of being selected for confirmation. Additionally, the selection of negative (credit) balances would be facilitated without special
considerations.
Mead computed the sample size using the risk of incorrect acceptance, the total recorded
book amount of the receivables, and the number of misstated accounts allowed. Mead
divided the total recorded book amount of the receivables by the sample size to determine
the sampling interval and then calculated the standard deviation of the dollar amounts of the
accounts selected for evaluation of the receivables.
Mead’s calculated sample size was 60 and the sampling interval was determined to be
$10,000. However, only 58 different accounts were selected because two accounts were so
large that the sampling interval caused each of them to be selected twice. Mead proceeded to
send confirmation requests to 55 of the 58 customers. Each of the three accounts originally
selected for the sample had insignificant recorded balances under $20. Mead ignored these
three small accounts and substituted the three largest accounts that had not been selected by
the random selection procedure. Each of these accounts had balances in excess of $7,000, so
Mead sent confirmation requests to these customers.
The confirmation process revealed two differences. One account with an audited value
of $3,000 had been recorded at $4,000. Mead projected this to be a $1,000 misstatement.
Another account with an audited value of $2,000 had been recorded at $1,900. Mead did not
count the $100 difference because the purpose of the procedure was to detect overstatements.
In evaluating the sample results, Mead decided that the accounts receivable balance was
not overstated because the projected misstatement ($1,000) was less than the allowance for
sampling risk.
