请问什么情况下需要放进restriction list，好像有好几种情况

问题如下：

DELI Company hired an investment management firm XY for the additional public offering. XY's brokerage unit now has a "sell" recommendation on DELI. The director of XY's investment banking department, Allen has asked Betty, who is the director of XY's brokerage unit, to change "sell" recommendation to "buy". Betty should:

选项：

A.

change the recommendation to “buy”.

B.

put DELI on a restricted list of XY and just give the factual information about DELI.

C.

reject Allen’s request and still keep the "sell" recommendation.

解释：

B is correct.

According to Standard I(B) Independence and Objectivity, when Betty is asked to change the recommendation, she should place DELI on a restricted list to aviod violating the Code and Standards.

根据准则I(B)，当Betty被要求改变关于DELI的投资建议时，她应当将DELI这家公司放入限制名单内以避免违反CFA准则。
