问题如下：
Ord Capital Management, an investment management firm that claims to comply with the GIPS standards, manages a global equity portfolio for a pension plan sponsored by Chimie bio-industrielle. On 15 April, the plan sponsor notifies Ord that the firm will be terminated as of the end of the month and instructs the manager to stop trading immediately. Ord should include the Chimie portfolio in the historical returns of the composite to which it belongs up to:
选项：
A.31 March.
B.15 April.
C.30 April.
解释：
A is correct.
Provision I.3.A.6 states, "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." The last full measurement period that the Chimie bio-industrielle portfolio was under the management of Ord Capital Management was the month of March. (See Section 3.9 of the reading.)
这道题可否这么看，因为强调的是plan to terminated, 因此，实际上4月15日这天只是一个composite 终止的预期，可能具体实施是4月底；因此根据"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."原则，3月份的业绩要保留；
对比另外一个题目（如下图），这里说的是已经在5月18日的时候结束了（received termination notification），这说明五月的业绩已经不能包含在composite当中了，往前推1个月的4月业绩也从composite计算中剔除了。所以4月底就应该移除了。
