John, CPA, is auditing the financial statements of ABC Bank Co. for the year ended December 31, 20×8. The following information is available:
(约翰,注册会计师,对ABC公司截止到20×8年12月31日的财务报表进行审查。可用的资料有:)
(a) John assessed the risk of material misstatements at 80% and plans to limit the audit risk to 10 %.
(约翰评估了重大错报风险为80%,并计划将审计风险控制在10%.)
(b) John is testing the operating effectiveness of the loan approval procedure ( a control activity) related to granting loans. In 20×8, ABC Bank granted to 10 000 loans in total. John determined that the acceptable risk of assessing control risk too low is 10%. He selected a sample of 60 sampling units and tested without any deviation found. Some Poisson Risk Factors(Reliability Factors) are reprinted as follows:
(约翰在检测相关贷款审核手续(控制活动)的经营能力时得知:在20×8年,ABC银行总共获得10 000元的贷款。约翰评定评估信赖过度风险为10%.他选择了60个抽样单位为样本,并且测试中没有发现任何偏差。一些Poisson风险因素(可靠性因素)如下:)
(c) John is using the Ratio Estimation Variable Sampling method to test the long-term loan balance at December 31,20×8. The total recorded balance is RMB¥;300 billion. John designed a sample of 200 items from a population of 4000 items. The book value of the sample is RMB¥;16.5 billion. However, the audited value is RMB¥;15.6 billion.
约翰使用了比率估计抽样来测试在20×8年12月31日的长期负债金额。总共记录的金额为人民币3000亿。约翰从总体为4000个项目中确定样本规模为200.样本的账面价值为人民币165亿,审定金额为人民币156亿。
(d) John is performing substantive procedures on interest income from short-term loan. The average annual market interest rate for short-term loan is 5 percent. The audited short-term loan balances of ABC Bank Co. at the end of each month in 20×8 are as follows:
约翰对短期贷款的利息收入实施实质性程序。短期贷款的平均市场年利率为5%,ABC银行在20×8每月月末的审计短期贷款金额如下:
Required:
要求:
(1) Based on (a), calculate the acceptable detection risk.
(1)基于(a)计算可接受的检查风险
(2) Based on (b), calculate the upper limit of population deviation rate.
(2)基于(b)计算总体偏差率的上限
(3) Based on (c), make a point estimate of the misstatement in the population.
(3)基于(c)计算总体中错报点估计值
(4) Based on (d), develop the expected result of interest income from short-term loan.
(4)基于(d)发展短期贷款利息收入的预期成效
(5) Assume that after the tests mentioned in (d), John discovered that the interest income from short-term loan was understated by RMB¥;15.6 billion. Prepare the adjusting accounting entry.
(5)假定在完成了提到的(d)步骤后,约翰发现短期贷款的利息收入被低估了156亿,编制调整会计分录:
参考答案:
(1)acceptable detection risk= audit risk/ the risk of material misstatements=10%/80%=12.5%(可接受的检查风险=审计风险/重大错报风险=10%/80%=12.5%)
(2)the upper limit of population deviation rate=Risk Factors/ sample size=2.3/60=3.83%
(总体偏差率上限=风险系数/样本量=2.3/60=3.83%)
(3)ratio=156/165=94.54%
estimate the actual value of the population=3000×94.54%=283.62 billion
a point estimate of the misstatement in of the population=3000-283.62×10=16.38 billion
[比率=156/165=94.54%
估计的总体实际金额=3000×94.54%=2836.2(亿元)
总体错报的点估计值=3000-2836.2=163.8(亿元)]
(4)the expected result of interest income from short-term loan=(300+320+310+300+330+320+320+290+310+330+300+290)×5%=18.6 billion
[推算的短期贷款期望利息收入=(300+320+310+300+330+320+320+290+310+330+300+290)×5%=186(亿元)]
(5)the adjusting accounting entry:
Dr:Interest suspense 156
Cr:Interest income 156
(调整分录:
借:应收利息 156
贷:利息收入 156)
