问题如下：
Pedro Ruiz is an analyst for a credit rating agency. One of the companies he follows, Eurexim SA, is based in France and complies with International Financial Reporting Standards (IFRS). Ruiz has learned that Eurexim used EUR220 million of its own cash and borrowed an equal amount to open a subsidiary in Ukraine. Ukraine is not currently in a hyperinflationary environment, but Ruiz is concerned that this situation could change. Ruiz also believes the euro will appreciate against the hryvnia for the foreseeable future.
Given Ruiz’s belief about the direction of exchange rates, Eurexim’s gross profit margin would be highest if it accounts for the Ukraine subsidiary’s inventory using:
选项：
A.FIFO and the temporal method.
FIFO and the current rate method.
weighted-average cost and the temporal method.
解释：
Ruiz expects the EUR to appreciate against the UAH and expects some inflation in the Ukraine. In an inflationary environment, FIFO will generate a higher gross profit than weighted-average cost. For either inventory choice, the current rate method will give higher gross profit to the parent company if the subsidiary’s currency is depreciating. Thus, using FIFO and translating using the current rate method will generate a higher gross profit for the parent company, Eurexim SA, than any other combination of choices.
何老师课上讲的是根据物价水平来判断。如果有物价上涨的趋势，那么FIFO 和 weight average cost 相比，FIFO 的成本更低，对应COGS也更低，（即COGS: FIFO < weight average cost ）这个可以理解。
但是题目中还有汇率变化的前提，题目中外币汇率的变化趋势是：H> A> CR，那么在Temper rate 前提下，对应汇率转化时，FIFO对应历史汇率转化COGS更大，但是 weight average cost 是用加权平均汇率转化的,COGS更小。（即COGS: FIFO> weight average cost ）
这两个结论似乎是相反的，综合选项A.C ，似乎没有理解，请老师指点一下，谢谢
