既然题目已经给出了年底的equity和NI，为何我们还要默认这上述这两个科目没有做过折旧呢？NI列示的时候，不是应该已经把折旧剔除了么？为何不能直接用NI除equity？谢谢

同学你好，这道题问的是，如果买的这个设备花的500000元直接费用化了，ROE应该是多少。题干给的数字确实如你所说，是扣掉了折旧的结果，但是这是资本化处理的NI和equity，我们不能直接用，需要调整成费用化的NI和equity。资本化的会计处理是资产负债表asset增加500000，利润表中有一笔折旧=500000/5=100000，对NI的影响是减少了100000*（1-27%），如果费用化，就没有了这笔折旧，要加回，即+100000*（1-27%），但是同时要增加一笔expense=500000，NI就会减少500000*（1-27%），总的费用化调整是： +100000*（1-27%）-500000*（1-27%）=-292000。所以如果算费用化的ROE，分子NI应该在资本化NI的基础上减少292000，因为NI变化会直接影响equity的变化，所以分母也调整相同金额。加油哦。

老师，第一年都已经过去，第一年的折扣已经折了，所以资本化的时候不应该用400000去算吗
