METHODOLOGY OF AUDIT ESTIMATION OF THE INTERCOMPANY CORPORATE CONTROL SYSTEM

It is substantiated and proposed in the article the methodology of audit assessment system of quality state of intercompany control, its components and the tools of practical use. It is presented the basic parametric model and the corresponding test questionnaire designed to establish the reliability level of the system of internal corporate controls of client-companies and the risk of its inefficiency. The logic of constructing a parametric model for testing: the intercompany corporate control system (ICCS) in the author's representation is to perform the following consecutive steps: to set the direction of testing in accordance with the system approach; to define the evaluation elements of the ICCS; to support the relevant areas of testing; to establish the relationship of certain valuation elements of the system of internal corporate control with the relevant components of the COSO ERM model; to determine the testing parameters of the ICCS as detailed components of the relevant assessment elements, taking into account the risk-oriented nature of the components of the COSO ERM model. It is substantiated that the directions of evaluation (testing) of the intercompany control system in the process of external audit are four aspects of the manifestation and existence of this system: structural, functional, sociopsychological, and informational. The sequence of stages of the assessment of the system of intercompany corporate control is determined by the following logic: determination of the reference state - testing and identification of the actual state of the parameters - identification of the actual level of reliability of the system of intercompany corporate control and its level of risk of inefficiency. The result of the evaluation of ICCS will be a certain amount of points - an integrated sum according to the specific indicators for the relevant parameters, based on their significance and degree of manifestation. The proposed methodological principles and methodology for carrying out an audit of the ICCS provide an indication of the risk of its ineffectiveness for the subsequent determination of the impact on the size of the risk of non-detection of distortions, the nature, timing and volume of external audit procedures.
