Artículo 16. Performing Analytical Procedures

.46 The auditor should perform analytical procedures that are designed to: Enhance the auditor's understanding of the client's business and the significant transactions and events that have occurred since the prior year end; and Identify areas that might represent specific risks relevant to the audit, including the existence of unusual transactions and events, and amounts, ratios, and trends that warrant investigation. .47 In applying analytical procedures as risk assessment procedures, the auditor should perform analytical procedures relating to revenue with the objective of identifying unusual or unexpected relationships involving revenue accounts that might indicate a material misstatement, including material misstatement due to fraud. Also, when the auditor has performed a review of interim financial information in accordance with AS 4105, he or she should take into account the analytical procedures applied in that review when designing and applying analytical procedures as risk assessment procedures. .48 When performing an analytical procedure, the auditor should use his or her understanding of the company to develop expectations about plausible relationships among the data to be used in the procedure. 27 When comparison of those expectations with relationships derived from recorded amounts yields unusual or unexpected results, the auditor should take into account those results in identifying the risks of material misstatement. Note: Analytical procedures performed as risk assessment procedures often use data that is preliminary or data that is aggregated at a high level, and, in those instances, such analytical procedures are not designed with the level of precision necessary for substantive analytical procedures.
