问题如下:
An analyst compiles the following data for a company:
Based only on the information above, the most appropriate conclusion is that, over the period FY13 to FY15, the company’s:
选项:
A.net profit margin and financial leverage have decreased.
B.net profit margin and financial leverage have increased.
C.net profit margin has decreased but its financial leverage has increased.
解释:
C is correct.
The company’s net profit margin has decreased and its financial leverage has increased. ROA = Net profit margin × Total asset turnover. ROA decreased over the period despite the increase in total asset turnover; therefore, the net profit margin must have decreased. ROE = Return on assets × Financial leverage. ROE increased over the period despite the drop in ROA; therefore, financial leverage must have increased.
解析:net profit margin=NI/revenue,从题目中找不到直接信息,但是可以分解ROA得到:ROA=(NI/revenue)*(revenue/asset),revenue/asset就是题目给的asset turnover,可以求出三年的net profit margin,从FY13到FY15分别是4.05、4和3.76,可以看出该比率在下降。Financial leverage可以通过分解ROE得到,ROE=ROA* leverage,ROA是下降的而ROE是上升的,所以leverage肯定是上升的。
为什么ROA=ROE*leverge?
谢谢
