In the year 2001, the European Comission started to revise the legislation Solvency I and to implement a new approach called Solvency II. The regulation called Solvency II is based on regulation considering management of risks of commercial insurance companies. Changes on financial markets and the contemporary financial crisis made financial authorities to formulate principles of regulation based on risk management. Commercial insurance companies across Europe will face a considerable amount of work to be ready for requirements related with Solvency II implementation in the year 2012.
Rating agencies, regulators and investors today are demanding that insurers provide detailed assessments of their risk tolerance and quantify the adequacy of their economic capital. To complete such assessments requires a credible baseline for underwriting volatility. Modern portfolio theory for assets teaches that increasing the number of stocks in a portfolio will diversify and reduce the portfolio risk, but will not eliminate risk completely, the systemic market risk remains. In the same way, insurers can reduce underwriting volatility by increasing account volume, but they cannot reduce their volatility to zero. A certain level of systemic insurance risk will always remain, due to factors such as for example the underwriting cycle, macroeconomic factors, legal changes and weather.
This presented scientific paper focuses on an analysis of specific goals of the regulation Solvency II and the structure of second pillar of the three-pillar construction (similarity with Basel II banking regulation) of Solvency II. The paper was written as part of research project MSM 6215648904, carried out by the Faculty of Business and Economics, under the title "The Czech Republic in the processes of integration and globalization, and the development of the agriculture and service sector in the new conditions of the integrated European market", following the goals and methodology of the research project.

Experimental works were focused on creation of optimal protocol for Acer davidii ssp. grosseri shoots multiplication. As the basic medium we used MS (Murashige α Skoog) culture medium enriched by cytokinins TDZ (Thidiazuron) and BAP (6-Benzylaminopurine) in different concentrations. There were used single nodal segments from four years old mother plants in experiments. Experiments were established in the middle of June in the phase of rapid growth of shoots. Cultivation conditions were: 21°C, light intensity 40 μmol.m^-2.s^-1, period of light 16 hours during the day. The reactions of explants were evaluated after six and twelve month. The results were statistically analysed. The explants of Acer davidii ssp. grosseri reacted differently on hormonal regulation. The lowest multiplication activity of explants was found out on MS culture medium enriched by 2,6 μM BAP. The average shoot multiplication on MS + 0,5 μM TDZ culture medium was 1,2. Multiplication 1,49 shoot per explants was found out on MS + 2,6 μM BAP + 0,5 μM TDZ. On the basic MS medium 1,35 shoots per explants multiplicated. In spite of positive influence of application of TDZ and BAP on shoot multiplication the results compared with multiplication on MS medium were statistically insignificant.
