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 use 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:
Would a change in the functional currency have any impact on financial statement ratios for the parent company, the change will most likely affect:
选项：
A.the cash ratio.
B.fixed asset turnover.
C.receivables turnover.
解释：
B is correct.
考点：会计方法对财务比率的影响。
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。
B选项的公式是fixed asset turnover=sales/fixed asset，分子sales是用平均汇率转换，这个在current method或者是temporal method下都是一样的。在current rate method下，分母fixed asset是用current rate转换。但是在temporal method下，它是用历史汇率转换的。所以会受到会计方法变化的影响。
A选项：cash ratio=cash/current liability，在这一题中current liability只有A.P，没有unearned revenue。所以无论是哪种方法转换，分子分母都用current rate。（注意所有负债都用current rate转换，除了unearned revenue，在temporal method下应该用历史汇率转换）
C选项：A.R turnover=revenue/A.R，无论是用哪种方法转换，revenue都用平均汇率，A.R都用current rate，所以不受会计方法的影响。
current vs temporal method 有没有归纳总结。
