Mary Kim, CFA, practices in the established country of Oldasia as well as in the emerging country of Newasia. By regulation, Oldasia prohibits licensed investment advisors from trading in securities ahead of their clients. Newasia has no laws or regulations in this area. Mary Kim may:（）
A. trade ahead of her clients in Newasia only.
B. trade simultaneously with her clients in Newasia only, as long as she has made full disclosure to her clients that she reserves the right to do this.
C. not trade ahead of her clients in either country.
参考答案：C
解析：
Under Standard Ⅰ (A), Mary Kim, as a CFA charterholder, must apply the CFA Institute Code and Standards or the controlling law, whichever is stricter. Because Standard Ⅵ (B) requires members to put client trades ahead of their own transactions, Mary Kim must follow the standard in the absence of governing law, or where the law is less strict than the standard.
