问题如下：
4. When recommending the mutual fund to Vanderon, does Klein violate any CFA Standards?
选项：
A.No.
B.Yes, relating to suitability.
C.Yes, relating to referral fees.
解释：
C is correct.
Klein violates Standard VI(C) relating to Referral Fees because he fails to provide appropriate disclosure. The Standard states that members must disclose the nature of the consideration or benefit—for example, whether flat fee or percentage basis; one¬time or continuing benefit; based on performance—together with the estimated monetary value. Although Klein acknowledges receipt of referral fees from the fund, he does not disclose an estimated dollar value or the nature of the consideration.
老师好！请问一下 怎么样披露referal fee 才算遵守了准则呢？
