The activities of economic entities are accompanied by a number of risks posed by the changes in the environment in which they operate. Economic theory and practice identify three basic types of risk – investment, financial and economic. The last one is a probability of adverse changes in market and economic conditions that affect the most important financial indicators of an enterprise. Business risk analysis is a system of special knowledge related to studying the economic processes in their mutual relation and dependence. It includes the quantitative measurement of factors determining the dynamics of risk indicators, as well as activities to minimize their impact. This article characterizes statistical methods of risk analysis that are applied in a case study using the measures of dispersion in three public limited companies.

The article answers questions like “What is sustainability of farms?”, “What are the mechanisms and modes of managing the sustainability of farms?”, and “How should we assess the sustainability level of farms?”. First, the evolution of the ‘concept’ of sustainable farming is analysed and defined as the ability of farms to maintain their managerial, economic, environmental and social functions in the long run. Second, the principal mechanisms and modes of managing the sustainability of farms are systematically approached. These include the institutional environment, market, private, collective, public and hybrid modes. Next, a system of criteria and indicators is proposed to assess the sustainability level of farms at the contemporary stage of development in Bulgarian agriculture. Finally, an approach to analysing and assessing the management system of farm sustainability is presented.

Instruments for an alternative approach to risk management in internal control systems under revolutionary changes in an organization’s development are presented in this paper. The functions and application of instruments for the identification and measurement of the threats to the organization are demonstrated in the first section of the paper. The role and application of instruments to counteract the threats to the organization are explained in the second section of the paper. The instruments proposed in the paper are illustrated with some results from the research project ‘Theoretical fundamentals of an internal standard of measurement and evaluation of threats to organizations’, financed by the National Science Fund of the Bulgarian Ministry of Education and Science.
