问题如下：
Ulta Beauty is a US-BASED corporation that sells cosmetic. Its Canadian subsidiary, Cosmetic firm, operates solely in Canada. It was created on 31 December 2015, and Cosmetic firm uses US dollar as its functional currency. Assume fixed assets were bought when the company was created.
The financial statement information for the years ended 2015 and 2016 on the following table:
If the functional currency were changed, please calculate the balance sheet exposure:
选项：
A.178
B.156
C.151
解释：
C is correct.
考点： current method exposure。
解析：之前美元是functional currency，即LC≠FC=RC，我们选择temporal method。现在如果FC改变，即使用current rate method进行转换。
所以exposure=TA-TL=586-162-273=151
老师，temporal method下，Balance sheet的exposure，应该是monetary asset - monetary liability吧？不应该是 total asset - total liability。因此没有正确答案。
原因：
1、讲义中，第201页，是monetary asset - monetary liability
2、逻辑上，用temporal method以后，固定资产的价格，一直用历史上采购时候的汇率转换，所以是不受汇率波动影响的。此道理，也适用于库存/未实现营收等实物形态的资产。所以，实物形态的资产，不应计入敞口中
3、此外，common stock（也就是原始股东出资，capital）以历史汇率转换，也不应包含在敞口（个人理解）。
请老师指导，谢谢！
