问题如下：
(1) Which of the assumptions in Exhibit 2 would most likely result in a lower reported post-employment benefit obligation for Euronet as compared with ZipTech?
选项：
A.Near-term health care trend rate
Ultimate health care cost trend rate
Years until the ultimate trend rate is reached
解释：
B is correct. Other things equal, a lower assumed ultimate health care trend rate would result in a lower benefit obligation and a lower periodic cost. Euronet’s 3.1% rate is lower than ZipTech’s 3.2% rate. A higher assumed near-term health care cost trend rate or a greater number of years until the ultimate trend rate is reached would result in a higher benefit obligation and a higher periodic cost. Both of these assumptions are higher for Euronet.
A is incorrect. Other things equal, a higher assumed near-term health care cost trend rate would result in a higher benefit obligation and a higher periodic cost. Euronet’s 4.1% rate is higher than ZipTech’s 3.6% rate.
C is incorrect. Other things equal, a greater assumed number of years until the ultimate trend rate is reached would result in a higher benefit obligation and a higher periodic cost. Euronet’s 10 years are greater than ZipTech’s 8 years.
我是从PBO = PV（benefit payment）的角度去理解，在benefit payment不变，discount rate不变的前提下，T越大，折现因子越小（1/(1+r)^T），PBO越小
从这个角度的话选了C
