Analytical Procedures in Planning the Audit


The purpose of applying analytical procedures in planning the audit is to assist in planning the nature, timing, and extent of auditing procedures that will be used to obtain evidential matter for specific account balances or classes of transactions. To accomplish this, the analytical procedures used in planning the audit should focus on (a) enhancing the auditor's understanding of the client's business and the transactions and events that have occurred since the last audit date, and (b) identifying areas that may represent specific risks relevant to the audit. Thus, the objective of the procedures is to identify such things as the existence of unusual transactions and events, and amounts, ratios and trends that might indicate matters that have financial statement and audit planning ramifications.


Analytical procedures used in planning the audit generally use data aggregated at a high level. Furthermore, the sophistication, extent and timing of the procedures, which are based on the auditor's judgment, may vary widely depending on the size and complexity of the client. For some entities, the procedures may consist of reviewing changes in account balances from the prior to the current year using the general ledger or the auditor's preliminary or unadjusted working trial balance. In contrast, for other entities, the procedures might involve an extensive analysis of quarterly financial statements. In both cases, the analytical procedures, combined with the auditor's knowledge of the business, serve as a basis for additional inquiries and effective planning.


Although analytical procedures used in planning the audit often use only financial data, sometimes relevant nonfinancial information is considered as well. For example, number of employees, square footage of selling space, volume of goods produced, and similar information may contribute to accomplishing the purpose of the procedures.
