Abstract
Risk assessment is an important task of risk management. It must take various aspects into consideration. For this reason the risk management involves various scientific disciplines: mathematics, psychology, law etc. Every institution must deal with many different kinds of risk. The question is: in order to ensure the continuation of the company, is it important to assess individual risk or to identify and evaluate the entire overall risk to the enterprise. This article aims to present a method of calculating the total organizational risk in relation to the ROI-return on investment (justifying the critical importance of profit [loss] in ensuring the continued operation of the entity).
