查询词典 risk

First, we discuss several theories of risk measures respectively such as theories ofcoherent measures of risk, spectral measures of risk and distortion measures of risk.Within the framework of these theories, we discuss and compare standard deviation,mean absolute deviation, lower partial moment, Ginis difference, VaR, CVaR and soon. We conclude that CVaR is superior to other measures with respect to theoreticalproperties.

The integrated risk between hydraulic, hydrologic uncertainty and the construction scheduling uncertainty should be analyzed. The paper puts forward the risk analysis model for the construction scheduling and the risk analysis model for construction diversion on the assumption that the construction scheduling is affirmable. Thus the Monte-Carlo method is used to simulate the integrated risk of construction diversion system considering hydraulic, hydrologic uncertainty and the construction scheduling uncertainty.

The CBRC allows commercial banks to implement the internal rating method by stages, however, when a commercial bank obtains the approval for using the internal rating method, its asset coverage ratio calculated according to the internal rating method (risk-weighted assets calculated according to the internal rating method)/(risk-weighted assets calculated according to the internal rating method + risk-weighted assets of other credit risk exposures calculated according to the revised capital supervisory provisions) shall not be lower than 50%, and it shall formulate the plan for the implementation of internal rating method by stages, so as to ensure that the asset coverage ratio reach 80% in three years.

银监会允许商业银行分阶段实施内部评级法，但在获得许可使用内部评级法时，采用内部评级法的资产覆盖率（按内部评级法计算的风险加权资产/［按内部评级法计算的风险加权资产＋按修订后资本监管规定计算的其他信用风险暴露的风险加权资产］）应不低于50％，并制定分阶段实施内部评级法规划，以保证3年内资产覆盖率达到80％。
