According to the results of Super-Radial (Super-CCR-I and Super-CCR-O) in 2021, no insurance company in Serbia was efficient. In the same year, according to the Super-Radial (Super-BCC-I) results, only two insurance companies in Serbia were efficient: DUNAV OSIGURANJE and ĐENERALI OSIGURANJE SERBIA. According to the results of Super-Radial (Super-BCC-O) in 2021 in Serbia, only two insurance companies were efficient: DDOR RE and SAVA ŽIVOTNO.Other insurance companies were ineffective. In order to improve the efficiency of insurance companies in Serbia, it is necessary, in addition to efficient adapting to a dynamic business environment, managing assets, capital, human resources, sales of insurance products and profits as efficiently as possible.
