Wu Yang, CFA, manages individual portfolios for Far East Trust Company. Hu Haiyun, a client, proposes to Wu Yang, "Any year my portfolio achieves at least a 20 percent return before taxes, you and your family can fly to Sanya in Hainan Province in China at my expense and use my condominium during the Spring Festival in February. " While Wu Yang does not inform his employer of the arrangement, he watches Hu Haiyun's portfolio performance intensively throughout the year and makes sure her account gets top priority for any partially executed block trade order. Hu Haiyun's portfolio return exceeds the 20 percent target for the year, and Wu Yang vacations in Sanya during the following February as Hu Haiyun's guest. According to the Standards of Professional Conduct, Wu Yang has least likely violated the CFA Institute Standards relating to:
A. fair dealing.
B. disclosure of conflicts.
C. priority of transactions.
参考答案：C
解析： Wu Yang没有披露给雇主他将会得到来自客户的礼物，违反了利益冲突的披露条款。 同时，Wu Yang确信Hu Haiyun的账户在部分执行的大宗交易中获得了最优的待遇，违反了公平对待的条款。在该题中，Wu Yang本人或者他的利益人并没有参与任何的交易行为，所有没有违反优先交易权条款。
