有个问题老师上课没讲到。因为减值使inv降低，同时cogs上升。但是cogs是i/s中的科目。如果inv下降，b/s就不平了呀，那b/s里面还需要调整哪一项科目使得两边平衡呢？
问题如下图：
选项：
A. 
B. 
C.

NO.PZ2016012102000113 问题如下 GoouCompany unr IFRS wrote its inventory value wn from cost of $10,000 to net realizable value of $8,000. Whiof the following is least likely regarng the financistatement effeof this change. A.loss reporteother comprehensive income. B.a seperate line item. C.increase in cost of sales. A is correct.If inventory writewn, will increase in cost of sales an a seperate line item on the income statement,考点LIFO和FIFO 如果存货发生减值，会增加在销售成本中，并单独列示（a seperate line item）. 存货减值的话不是cogs增加吗？为什么还需要单独列示？
