All health insurance companies operating in Slovakia met the required solvency rate of at least 3 percent last year. This information stems from the report on performance of the Healthcare Supervision Office (UDZS) in 2006, presented on Friday by UDZS head Richard Demovic. The actual solvency rate of health insurers ranged between 1.4-times to 12.17-times the minimum required rate as of December 31, 2006. Vseobecna Zdravotna Poistovna showed the lowest solvency rate of 4.19 percent. On the other hand, health insurer Dovera reported the highest solvency rate of 35.32 percent.
