  1. Four rules to audit sampling
    • 1) Central limit theorem (population is normally distributed into normal/bell-shaped curve)
    • 2) Samples must be unrestricted (equally chance of being selected) and randomly selected (no bias)
    • 3) If sample is large enough and randomly selected, sample will be representative of the population
    • 4) Standard deviation is a sample risk, the measure of variability
  2. Statistical sampling vs. nonstatistical sampling
    • - Both are GAAS
    • - Statistical sampling specifies risk willing to accept, calculate sample size, and results are evaluated quantitatively
    • - Nonstatistical sampling means auditor uses judgment to determine sample size and results are evaluated judgementally
  3. Advantages to statistical sampling
    • - Measure sufficiency of the audit evidence obtained
    • - Provide an objective basis for quantitatively evaluating sample results
    • - Design an efficient sample
    • - Quantify sampling risk so as to limit risk to an acceptable level
  4. Sampling concepts do not generally apply to
    • - Risk assessment procedures performed to obtain an understanding of internal controls
    • - Tests of automated application controls when effective general controls are present
    • - Analyses of security and access controls
    • - Some tests related to the operation of the control environment
  5. Sampling risks in substantive testing (variable sampling)
    • - Risk of incorrect acceptance (beta risk) = saying it's not materially misstated when it is
    • - Risk of incorrect rejection (alpha risk) = saying it's wrong when it's right (lack of efficiency since we do more work)
  6. Sampling risks in tests of controls (attribute sampling)
    • - Risk of assessing control risk too low (beta risk) = level of risk is not low but it really is (risk of over-reliance)
    • - Risk of assessing control risk too high (alpha risk) = level of risk is higher than it is (risk of under-reliance, lack of efficiency)
  7. Attribute sampling
    • - Estimating rate of occurrence of an attirubte, to test operating effectiveness of control
    • - Tolerable deviation rate is maximum rate of deviation (risk of misstatement)
    • - Deviation rate is auditor's best estimate of deviation rate in population from what was tested (upper deviation rate in range)
  8. Steps performed in attribute sampling
    • - Define the objective of the test
    • - Define the population
    • - Define the sampling unit
    • - Define the attributes of interest (unique to attribute sampling)
    • - Determine the sample size
    • - Select the sample (random selection, systematic selection, block sampling NOT acceptable)
    • - Evaluate the sample results
    • - Form conclusions about the internal control tested
    • - Document the sampling procedure
  9. Factors in determining the sample size of attribute sampling
    • - Risk of assessing control risk too low (inverse relationship to sample size)
    • - Tolerable deviation rate (max rate of error acceptable; inverse relationship to sample size)
    • - Expected deviation rate (best estimate, direct relationship to sample size)
    • - Population size isn't an issue
  10. Forming conclusions about internal control tests from attribute sampling
    • - If upper deviation rate (sample deviation + allowance) is less than or equal to auditor's tolerable deviation rate, auditor may rely on control
    • - If not, then auditor should modify NET of substantive testing or test compliance with other internal accounting control
  11. Discovery sampling
    Special type of attribute sampling appropriate when auditor believes population deviation rate is zero or near zero, and when no deviations are found in sample size then auditor can be 95% confident that rate of deviation doesn't exceed 1%
  12. Variable sampling
    • - Obtain evidence about reasonableness of monetary values
    • - Tolerable misstatement is maximum monetary misstatement auditor is willing to accept
    • - Use stratification to separate groups and increase efficiencies (when lots of variability)
  13. Types of variable sampling plans
    • - Mean-per-unit estimation (use average value of items in sample to estimate true population value), don't need to use BV of population
    • - Ratio estimation (audit items true value/audited items BV x total book value is point estimate), efficient when calculated audit amounts and approximately proportional to the client's book amounts
    • - Difference estimation (average difference between audited value and book value to project actual population value (divide by items tested and multiple by population to get adjustment rate), efficient when differences aren't as proportional to BV( instead of ratio estimation)
  14. Steps performed in variable sampling
    • - Define objective of test
    • - Define the population
    • - Define the sampling unit
    • - Determine the sample size
    • - Select the sample (random sampling)
    • - Evaluate the sample results
    • - Form conclusions about the balances/transactions tested
    • - Document the sampling procedure
  15. Factors in determining the sample size in variable sampling
    • - Tolerable misstatement = inverse
    • - Expected misstatement (size/frequency/etc) = direct
    • - Acceptable level of risk (audit risk/risk of incorrect acceptance/risk of incorrect rejection) = inverse
    • - Characteristics of the population = standard deviation = direct
    • - Assessed risk of matterial misstatment (IR x CR) = direct
  16. Evaluating sample results of variable sampling
    Project misstatements onto population, and obtain a "point estimate". Then add allowance for sampling risk and determine if record book value follows within acceptable range. If so, BV is fairly state (if sample is representative of population)
  17. Probability-proportional-to-size sampling
    • - Individual dollar in population selected and that account is audited (hybrid method), designed to detect overstatement errors
    • - Sampling interval = tolerable misstatement / reliability factor
    • - Sample size = recorded amount of population / sampling interval
    • - Start with random start and go with that
    • - Projected error is difference between recorded amount and audit amount (divided by recorded amount) and that percentage put on the sample interval
  18. Situations when internal-control matters are communicated
    • - Financial statement audit (non-issuers)
    • - Examination of internal control (non-issuers), integrated with audit of F/S
    • - Audit of internal controls (issuers), integrated with audit of F/S
  19. Definition of control deficiency
    Exists when design or operation of a control doesn't allow management or employees in the normal course of performing their assigned functions to prevent, detect and correct (or prevent and detect for issuers) misstatements on a timely basis, usually based on design or operation
  20. Definition of material weakness
    Deficiency or a combination of deficiencies in internal control over financial reporting so that there's a reasonable possibility that a material misstatement of the entity's F/S will not be prevented, detected or corrected (prevented or detected) on a timely basis
  21. Definition of significant deficiency
    A deficiency, or a combination of deficiencies, in internal control that is less severe than material weakness, yet important enough to merit attention by those charged with governance
  22. Indicators of material weakness
    • - Identification of any level of fraud (even immaterial fraud) perpetrated by senior management
    • - Restatement of previously issued F/S to correct a material misstatement
