IMPROVEMENT OF INTERNAL CONTROL ASSESSMENT QUESTIONNAIRE IN COMMUNICATION ENTERPRISES INVENTORY AUDIT BASED ON HAS 240 AND HAS 315 REQUIREMENTS

Abstract

The article studies the issues of improving the methodology for assessing the internal control
system in the audit of inventory in telecommunications enterprises. Fraud risks specific to the communications
industry — SIM card reuse, theft of cable products, write-off of equipment, abuses associated with scratch
cards, and concealment of technological depreciation — are systematized and their mechanisms of influence
on financial reporting are revealed. As a result of the study, an improved internal control questionnaire for
the audit of inventory, consisting of seven sections and 25 questions, was developed, taking into account the
requirements of international auditing standards (ISA 240 “The Auditor’s Responsibility for Fraud in an Audit
of Financial Statements” and ISA 315 “Identifying and Assessing the Risks of Material Misstatement”) and
network fraud risks. The structure of the questionnaire, the distribution of questions by risk levels, the scale of
the answers and the procedure for connecting the results to the audit program are explained on the example of
the joint-stock company “Uzbektelecom”.
