for identified risks of material misstatement at the assertion level.[5] In the context of ASA 540, and depending on the nature of a particular accounting estimate, the susceptibility of an assertion to a misstatement that could be material may be subject to or affected by estimation uncertainty, complexity, subjectivity or other inherent risk factors, and the interrelationship among them. As explained in ASA 200,[6] inherent risk is higher for some assertions and related classes of transactions, account balances and disclosures than for others. Accordingly, the assessment of inherent risk depends on the degree to which the inherent risk factors affect the likelihood or magnitude of misstatement, and varies on a scale that is referred to in this Auditing Standard as the spectrum of inherent risk. (Ref: Para. A8–A9, A65–A66, Appendix 1)

5.                   This Auditing Standard refers to relevant requirements in ASA 315 and ASA 330, and provides related guidance, to emphasise the importance of the auditor's decisions about controls relating to accounting estimates, including decisions about whether:

           * There are controls required to be identified by ASA 315, for which the auditor is required to evaluate their design and determine whether they have been implemented.

           * To test the operating effectiveness of controls.

6.                   ASA 315 also requires a separate assessment of control risk when assessing the risks of material misstatement at the assertion level. In assessing control risk, the auditor takes into account whether the auditor's further audit procedures contemplate planned reliance on the operating effectiveness of controls. If the auditor does not plan to test the operating effectiveness of controls, or does not intend to rely on the operating effectiveness of controls, the auditor's assessment of the control risk is such that the assessment of the risk of material misstatement is the same as the assessment of inherent risk. (Ref: Para. A10)

7.                   This Auditing Standard emphasises that the auditor's further audit procedures (including, where appropriate, tests of controls) need to be responsive to the reasons for the assessed risks of material misstatement at the assertion level, taking into account the effect of one or more inherent risk factors and the auditor's assessment of control risk.

8.                   The exercise of professional scepticism in relation to accounting estimates is affected by the auditor's consideration of inherent risk factors, and its importance increases when accounting estimates are subject to a greater degree of estimation uncertainty or are affected to a greater degree by complexity, subjectivity or other inherent risk factors. Similarly, the exercise of professional scepticism is important when there is greater susceptibility to misstatement due to management bias or other fraud risk factors insofar as they affect inherent risk. (Ref: Para. A11)
