A walkthrough is a process of tracing a transaction from origination, through the issuer’s information systems, to the issuer’s financial reports. A walkthrough can assist certifying officers to confirm that:
(a) they understand the components of ICFR, including those components relating to the prevention or detection of fraud;
(b) they understand how transactions are processed;
(c) they have identified all points in the process at which misstatements related to each relevant financial statement assertion could occur; and
(d) the components of ICFR have been implemented.
