问题如下：
Snow Creek Village West offers its employees a defined benefit pension plan and stock option, Snow Creek Village West complies with US GAAP.
The information on the following table:
Compared to the 2018 reported financial statement, if Snow had used the same expected long-term rate of return on plan assets assumption in 2018 as it used in 2016, its year-end 2018 pension obligation would most likely have been:
选项：
A.higher
B.lower
C.the same
解释：
C is correct.
考点：养老金的假设
解析：
expected long-term rate也就是E(R)，在美国准则下，E(R)用来计算损益表中的Expected return on plan assets一项。pension obligation是资产负债表中的养老金负债科目。其计算思路有两个：
1、直接将预计未来要支付给退休员工的现金流用discount rate折现到所求PBO的时点。
2、用期初PBO加减当期增加或减少PBO的各项，得到期末PBO（BASE法则）
不管是哪个思路，都能看出在计算PBO时，并没有用到养老金资产的回报率，所以不管计算return on plan assets用的expected long-term rate是多少，不会影响到PBO的计算，选项C正确。
题目不是说了 如果这个rate保持不变的话，会怎么变吗？ 但是discount rate 变少了，那么PBO不是就变高了么？
