The analytical procedures we perform as an overall analytical review of the financial statements are more similar to those we perform as risk assessment procedures than those we perform as substantive analytical procedures (i.e., they provide a broad indication rather than providing substantive evidence about individual accounts and disclosures (as described in SUBSTANTIVE Appendix 1). We therefore complete the overall analytical review at a similar level of disaggregated detail used to perform analytics as risk assessment procedures.
The overall analytical review allows us to pull together the conclusions from all our audit procedures and consider whether they are consistent with the financial statements as a whole. In addition, we design analytical procedures for insignificant accounts to confirm that the amounts are consistent with our expectation that they are insignificant. We may perform these procedures as part of our final overall financial statements review.
We update our analytical procedures performed as risk assessment procedures related to revenue through period end with the objective of identifying unusual or unexpected changes in revenue or related accounts.
