你好

NO.PZ2016012101000130

问题如下:

A decomposition of ROE for Integra SA is as follows:

Which of the following choices best describes reasonable conclusions an analyst might make based on this ROE decomposition?

选项:

A.

Profitability and the liquidity position both improved in FY12.

B.

The higher average tax rate in FY12 offset the improvement in profitability, leaving ROE unchanged.

C.

The higher average tax rate in FY12 offset the improvement in efficiency, leaving ROE unchanged.

解释:

C  is correct.

The increase in the average tax rate in FY12, as indicated by the decrease in the value of the tax burden (the tax burden equals one minus the average tax rate), offset the improvement in efficiency indicated by higher asset turnover) leaving ROE unchanged. The EBIT margin, measuring profitability, was unchanged in FY12 and no information is given on liquidity.

解析:考察的知识点是ROE的分解,其中衡量profitability的是EBIT margin,该比率没变,所以probability没有改善,A不对。Tax burden=NI/EBT=(EBT-tax)/EBT=1-tax rate,tax burden下降说明税率上升,B说税率上升带来的对ROE的负面影响被profitability的提高抵消了,但是profitability没变,所以B不对。C说税率上升带来的对ROE的负面影响被efficiency的提高抵消了,efficiency用asset turnover衡量,确实是变好了,所以C正确。

老师这是杜邦的五步法,能不能稍微具体解释一下怎么来看这样的变动会造成efficiency还是profitability的变化呀。谢谢

嗨,爱思考的PZer你好:


这一题考的是杜邦5分解,首先需要把公式写出来。每一项对应的是题目的5项

其中可以看到ROE 18.9%没有变化,2,3,5的数字是一样的,说明也没有变化。不同之处是1和4.

其中1是tax burden,它=1-tax rate, 我们可以看到tax burden是下降的,说明tax rate上升。

而4是asset turnover,它衡量了asset的效率(efficiency),是上升的。

从这些信息可以看出,效率上升,会使ROE上升,但tax rate上升, 使得tax burden下降,从而ROE下降,因此ROE整体看是没有变化的。

A不对,因为2是衡量profitability的指标,它是不变的,所以profitability没有improve。从这个表格中没有体现liquidity的信息,所以没有办法对liquidity下结论

B不对,因为profitability没有improve,而是efficiency上升了,所以选C
