Abstract
The purpose of this research is to test the resilience of issuers to the financial pressure generated by the commitments made in connection with the issuance of debt instruments (bonds) and to identify issuers whose financial position and performance present the susceptibility of a major default risk. The research actions involved determining the indicators specific to the fundamental analysis, applying the classic insolvency risk assessment models (Altman and Conan Holder) and assessing the future evolution of the key financial indicators on the basis of the forecasts. The results obtained confirm or disprove the existence of significant uncertainties regarding the ability to repay the bond loans.
