问题如下：
Beta Investment Corporation claims to comply with the GIPS standards. On 18 May, the firm received a notification of a portfolio’s termination. When should the portfolio be removed from the composite if composite returns are calculated monthly?
选项：
A. 30 April
B. 18 May
C. 31 May
解释：
A is correct.
考点：3.A Composite construction-3.A.6
解析：条款3.A.6 Terminated portfolios must be included in the historical performance of the composite up to the last full measurement period that each portfolio was under management
终结的组合必须被包含记录在Composites的历史业绩中，过去的历史业绩必须持续记录至该组合上一个完整的业绩评估周期结束为止。
18 May的last full measurement period是4月，所以在四月底，也就是4月30日把这个portfolio移除。
根据题目里说的，5/18才终止，那么5/18之前这个portfolio还在运行啊。那个它的最后一个完整的measurement 不应该是5月份吗？
