Starting percentages for materiality bases

W&S Partners commenced the risk assessment phase of the Cloud 9 audit with procedures to gain an understanding of the client's structure and its business environment. You have completed your research on the key market forces as they relate to Cloud 9's operations. The topics you researched included the general and industry-specific economic trends and conditions; the competitive environment; product, customer, and supplier information; technological advances and the effect of the Internet; and laws and regulatory requirements. The purpose of this research is to identify the inherent risks. The auditor needs to identify which financial statement assertions may be affected by these inherent risks. Identifying the risks will help determine the nature of the audit procedures to be performed. Management implicitly or explicitly makes assertions regarding the recognition, measurement, presentation, and disclosure of the various elements of the financial statements. Auditors use assertions for account balances to form a basis for the assessment of risks of material misstatement. That is, assertions are used to identify the types of errors that could occur in transactions that result in the account balance. Consequently, further breaking down the account into these assertions will direct the audit effort to those areas of higher risk. The auditors broadly classify assertions as existence or occurrence; completeness; valuation or allocation; rights and obligations; and presentation and disclosure. An additional task during the risk assessment phase is to consider the concept of materiality as it applies to the client. The auditor will design procedures in order to identify and correct errors or irregularities that would have a material effect on the financial statements and affect the decision-making of the users of the financial statements. Materiality is used in determining audit procedures and sample selections, and in evaluating differences between client records and audit results. It is the maximum amount of misstatement, individually or in aggregate, that can be accepted in the financial statements. In selecting the base figure to be used to calculate materiality, an auditor should consider the key drivers of the business and ask, "What are the end users (that is, shareholders, banks, and so on) of the accounts going to be looking at?" For example, will shareholders be interested in profit figures that can be used to pay dividends and increase share price? W&S Partners' audit methodology dictates that one planning materiality (PM) amount is to be used for the financial statements as a whole. Further, only one basis should be selected?a blended approach or average should not be used. The basis selected is the one determined to be the key driver of the business. W&S Partners uses the percentages in below given table as starting points for the various bases.
