Implementation of the “bail-in” mechanism in the banking system of Ukraine

The aim of the article was to find out the optimal capital structure of the companies in relation to their maximum performance. To reach this aim, the data of the companies operating in the field of heat industry of the Slovak Republic were used. As the first method, a correlation matrix was applied. It was found out that there is statistically significant relationship between capital structure indicators and performance of the companies. Due to the lack of data in time series, the authors were not able to apply multiple regression model to assess the impact of these indicators on performance. Therefore, a method of modelling was used to analyze the impact of the change in capital structure on performance. Modelling was based on the principle of a gradual change in the capital structure in favor of debt. By the increase in debt, it was confirmed that there was a change in the values of selected indicators. In the course of analysis, it was confirmed that the value of EVA equity increased with the rising indebtedness by which the proposition I of the modified MM theory was supported. The performance expressed by EVA entity indicator is at its minimum when the capital structure is 90:10 in favor of equity. By increasing the debt, EVA entity rises. Based on these results, it can be stated that the performance of selected companies increases when the share of debt also rises, even when taking into account the rising financial risks.

The urgency of the issue is related to changes in the Ukrainian banks’ business environment, taking into account the impact of domestic and global financial instability and the implementation of the regulatory framework for banking regulation of the National Bank of Ukraine in accordance with the Basel Committee on Banking Supervision recommendations. The main goal of this research is to analyze the degree of implementation and compliance with the Basel III regulations in Ukrainian banking system. To carry out the research, regulatory and legislative documents of the National Bank of Ukraine, the Basel Accords, statistic data of the Ukrainian banks and the National Bank of Ukraine were used. For this purpose, the analysis of main indicators of Ukrainian banks’ financial stability within the period of 2014–2017 is made. Thus, post-crisis regulatory changes have aimed at restoring bank stability. The results seem to suggest that bank regulatory changes may be repressive, for instance, cleaning and optimization of the banking system as an effective tool for anticrisis management. As a result, it was concluded that banks with foreign capital are the most stable in the banking system of Ukraine in comparison with domestic banks.

This paper aimed to empirically examine the extent to which capital structure impacts the profitability of Nigerian Deposit Money Banks considering the profitability of eight Nigerian Deposit Money Banks from 2003 to 2018 (16 years). A descriptive research design was adopted for this study, and data were analyzed using regression. The study used secondary data obtained from published annual reports of selected Nigerian Deposit Money Banks on the Nigerian Stock Exchange (NSE) for four years (2003–2018). The study concluded that the indicators used to measure capital structure (debt-equity ratio and leverage ratio) and profitability (returns on equity) had a negative relationship. This means that the use of debts mixed with equity (debt-equity ratio and leverage ratio) in improper proportion as financing methods can negatively affect profitability. Hence, there is a need to identify the optimal mix of capital structure (debts mixed with equity) that maximizes profitability, as well as firm and shareholder value with minimum agency costs as suggested by the trade-off theory and agency theory, respectively. The alternative is to give preference to retained earnings (internal source of finance) as funding source.
