请问老师可以把考场上打的公式写一下吗

  1. CFA III
  2. 机构IPS

NO.PZ2019100901000018

问题如下：

Meura Bancorp, a US bank, has an equity capital ratio for financial assets of 12%. Meura’s strategic plans include the incorporation of additional debt in order to leverage earnings since the current capital structure is relatively conservative. The bank plans to restructure the balance sheet so that the equity capitalization ratio drops to 10% and the modified duration of liabilities is 1.90. The bank also plans to rebalance its investment portfolio to achieve a modified duration of assets of 2.10. Given small changes in interest rates, the yield on liabilities is expected to move by 65 bps for every 100 bps of yield change in the asset portfolio.

Calculate the modified duration of the bank’s equity capital after restructuring. Show your calculations.

选项：

解释：

The modified duration of the bank’s equity capital after restructuring is 9.89 years:


谢谢，有点不清楚具体怎么写最方便？这里面的公式哪些可以用文字描述，哪些必须要打公式？乘号和除号，能直接写 "x" 和 "/" 吗？

嗨，努力学习的PZer你好：


那乘号能直接用键盘写上的x 、除号能写 /吗（就是不用公式编辑器里的）


看了下协会官网，只说了不能用星号，必须要用公式输入器里面的×；

但是除法没有说，所以除法“/”应该是可以用的。

嗨，努力学习的PZer你好：


我就是觉得公式编辑器太复杂了，找符号很耗时间，想知道哪些符号是可以允许的快捷方法


没有快捷方法，比如乘号要在编辑器里找到“×”，而不能用*。

能用到的基本就是加减乘除，编辑器里面相对好找。

虽然现在很辛苦，但努力过的感觉真的很好，加油！

嗨，爱思考的PZer你好：


有点不清楚具体怎么写最方便？


直接填答案即可。现在的考试计算题不要求写过程。


但是！

如果计算错了，那么直接是零分。所以我们建议是：填完答案之后。简单地写一下计算过程。这样即便答案错了，但过程是OK的，协会会给应的步骤分。

比如，上面这道题，先把公式打出来，然后带入相关数据。

打公式的话，协会机考软件有公式编辑器，可以找到相关的符号，我们会用到的符号编辑器里都有。


这里面的公式哪些可以用文字描述，哪些必须要打公式？


像这种稍微复杂点的公式，就用公式打出来。然后填数据。

而那种很简单的，如immunization时，Asset BPV = Liability BPV，直接写即可。


乘号和除号，能直接写 "x" 和 "/" 吗？


考试软件有公式编辑器，可以找到我们会碰到的所有符号。
