NO.PZ201806201100001102 问题如下 With respeto Statement 2, whwoulthe most likely effein 2010 if AMRC were to switto acceleratepreciation methofor both financiantreporting? A.Net profit margin woulincrease. B.Totasset turnover woulcrease. C.Cash flow from operating activities woulincrease. C is correct. In 2010, switching to acceleratepreciation methowoulincrease preciation expense ancrease income before taxes, taxes payable, annet income. Cash flow from operating activities woulincrease because of the resulting tsavings. CCash flow from operating activities woulincrease. 请问C，加速折旧为什么影响现金流?如果发生折旧 → COGS增加 → E减少 → （财务报表）tax减少 →（财务报表） CFO增加，但是税法对税额的缴纳有自己的体系，所以实际缴纳的税额不变。所以税务报表的tax并没有发生变化。请问老师我这样理解哪里出现错误。谢谢老师。
NO.PZ201806201100001102 看题目解析，其中提到加速折旧有抵税作用，会影响应纳所得税，从而影响到现金流。但强化课中有关折旧这里，说2种折旧方法对税没有影响。不知道这里如何理解？

Cash flow from operating activities woulincrease because of the resulting tsavings. 折旧为什么会影响现金流呢？？
为什么B不对，因为加速折旧，NI减少，revenues减少，asset tunover减少
