问题如下：
Fabian, CFA, work on the Equity investment company. Golden Elementary school paid ￥360 million to purchase 50 percent Frost Early Education Center on 31 December 2018. The excess of the purchase price over the fair value of Frost’s net assets was attributable to previously unrecorded licenses. These licenses were estimated to have an economic life of five years. The fair value of Frost’s assets and liabilities other than licenses was equal to their recorded book value.
Golden and Frost’s condensed income statements for the year ended 31 December 2018, and Balance Sheet are presented the following table：
Golden’s long-term debt to equity ratio on 31 December 2018 most likely will be lowest if the results of the acquisition are reported using:
选项：
A.the equity method
B.consolidation with full goodwill
C.consolidation with partial goodwill
解释：
A is correct.
考点：不同的合并会计报表方法下，会计科目的对比。
解析：
（1）如果使用equity method，long-term debt to equity=520/1,330=0.39
（2）如果使用consolidation method, long-term debt to equity=（母公司的long-term debt加子公司的long-term debt）/（母公司的equity+子公司的MI）
子公司的MI并不是565*50%，因为有previously unrecorded licenses。
根据题目信息：母公司花了360买了子公司50%的股权，多花的钱是为了买unrecorded licenses，这些license的价值是不包含在子公司的资产1050中的。但在合并报表的时候，应该将子公司未入账的资产也合并进来。licenses的价值需要我们自己计算。
股权只买了一半，相当于license也只买了一半，360/50%=720为如果要买100%的license，母公司需要支付的钱，减掉子公司资产负债表上面的FV of net identifiable asset 565，就是license的价值。即：unrecorded licenses=720-565=155
加入unrecorded licenses之后，子公司资产增加155，equity增加155，quity=155+565=720， 其中母公司只持股50%，因此有50%是归属于少数股东的部分：MI=720*50%=360因此：
如果使用consolidation method, long-term debt to equity=(520+390)/(1,330+360)=0.54
低于equity method下计算的ratio，选项A正确。
（本题无goodwill，因此选项B、C没有区别，不需要比较）
老师请问，“Golden Elementary school paid ￥360 million to purchase 50 percent Frost Early Education Center”已经出资购买了Frost 50% 权益怎么还能使用Equity Method? 不是已经达到control状态了吗？
