ヾ(◍°∇°◍)ノ゙你好同学,
1. 理解这句话需要关联“contingent immunization”
Contingent Immunization或有免疫:
当present value of asset portfolio 远大于 present value of liability,就产生了较明显的surplus,而这部分surplus并不会对免疫策略产生影响。因此可使用这部分surplus做主动投资,也可全部进行主动投资,但需要监控结束Contingent immunization的时间点。另外当actively managed portfolio < specified threshold→active management ceases。
题目中标黄的内容“surplus exceeds her threshold of 4% of asset”
Puhuyesva设置了一个门槛值,门槛值=4% of asset
present value of asset portfolio - present value of liability = surplus > 4% of asset
按照题目给的信息:USD217.3 million - USD206.8 million > 4% of USD217.3 million
用解析里的除法也可以说明同样的道理:Because the value of assets is more than 4% greater than the value of liabilities (217.3/206.8 – 1 = 5.1%)
2.题目给了条件(Puhuyesva认为收益率会下降),请参考截图1,第三段话,第一行
“Puhuyesva believes interest rates will fall over the next three months and wants to position the asset portfolio accordingly”
