The Group’s main assumption as regards managing its financing sources is to develop an optimal equity and liabilities structure in order to reduce the cost to finance its operations, secure an investment grade credit rating and financing sources for the operating and investing activities of the Group and its subsidiaries. Activities undertaken in this area intend to ensure the Group’s financial security and satisfactory value for its shareholders. In optimising the equity and liabilities structure by using financial leverage, it is important to maintain a capital base at a level sufficient to develop the trust of investors, lenders and the market. The Group monitors the effectiveness and stability of its capital using the debt ratio and return on capital ratios. The Group aims to increase capital effectiveness while retaining it at a safe level. The Group describes the above-mentioned indicators in the Management Board Report on ENEA S.A.’s and ENEA Group’s Activities in 2020.
