NO.PZ2015121801000033问题如下entity choosing to accept a risk exposure may:A.buy insurance.B.enter into a rivative contract.C.establish a reserve funto cover losses.is correct.Risk acceptanis similto self-insurance. entity choosing to self-insure mset up a reserve funto cover losses. Buying insuranis a form of risk transfer anusing rivatives is a form of risk-shifting, not risk acceptance.买保险是转移风险敞口，B和C应该怎么区分
risk transfer是指将风险转移出去，改变风险承担对象，比如让保险公司承担风险，risk shifting是指将某种风险转换成另一种风险，比如用衍生品把信用风险转换成流动性风险？是这样理解吗，有没有哪里理解错了
老师 这道题目的考点是在讲义哪里？ 我的理解是ABC都是可以应对风险敞口的方法啊
reserve fun怎么操作的？就像ballowance那样吗？
