Gordon is a CFA charter holder and the pension fund manager for a worker’s union. The union president informed him that during a union meeting today with Zinc Limited he learned that Zinc will announce several plant closings tomorrow. Because the worker’s union pension has a sizable position in Zinc, the union president wants Gordon to sell the pension’s holdings in Zinc today before the announcement is made public. Gordon should:（）
A. inform AIMR in writing of the union president’s request.
B. contact the Justice Department and tell them about the union president’s request.
C. tell the union president that this action is illegal and refuse to sell the stock until after the announcement.
参考答案：C
解析：
Standard Ⅴ (A) Prohibition against Use of Material Nonpublic Information. The union president has material nonpublic information. Grodon received material nonpublic information in confidence. Therefore, he is not permitted to breach that confidence by trading in securities to which such information relates. Parker should make a reasonable effort to achieve public dissemination of material nonpublic information disclosed in breach of duty.
