The following methods of scientific research have been used to achieve the set goal and to solve certain tasks: analysis - to study the scientific-theoretical and applied base in the field of management of non-current assets; system approach – for building a comprehensive understanding of the essence of non-current assets; grouping method – to identify the systemic influence of factors on the formation of a single category interpretation; method of morphological analysis – to clarify the conceptual-categorical apparatus.
