International Auditing Standards in the United States : Comparing and Understanding Standards for ISA and PCAOB (2ND)

International Standards on Auditing (ISA) are standards or guidelines that auditors follow when conducting a financial audit of a companys financial statements in those jurisdictions that have adopted ISAs or some version of ISAs.

The problem for both practitioners and students is that the auditing principles of the ISA and the AICPA are not identical, even though they are moving towards convergence, or at least attempting to do so. That said, the standards of the ISA and AICPA still differ; and this problem is compounded because of the significant differences between the standards of ISA and PCAOB. In fact a study commissioned by the European Community found at least five areas where there are substantial differences. The areas of substantive differences relate to: Assessing and reporting on internal control Reference to the work of another auditor in a group audit Documentation requirements Risk assessment and responses to assessed risks. This is probably one of the most significant differences. Going concern reporting. Under the PCAOB the foreseeable future is limited to 12 months but under
