Any company, and especially an actively developing one, constantly feels the need to attract financial resources. Debt capital plays an important role for companies as an additional means for expanding and carrying out economic activities. Accordingly, effective management of borrowed capital is economically beneficial for the company, and the wrong approach to the formation of borrowed sources of the company can adversely affect its financial condition. The object of research in this article was PJSC “MegaFon”. A characteristic feature of this industry is the increased competition due to the aggressive policies of both telecom operators and companies that have entered this market from related industries. In the study, the process of forming borrowed funds by the company is presented in the form of five consecutive stages. The approbation of the proposed research scheme, using the example of PJSC “MegaFon”, showed the ambiguity of the financial decisions made to attract borrowed capital. And the main recommendation is to attract borrowed funds only for the development of the company.
