Colin Caldwell, CFA, is the chief investment officer of Northwest Mutual Fund, whose investment objective is to invest in fixed income emerging market securities. Caldwell allocates the fund's assets primarily to bonds of commodity producers in emerging markets and invests in a combination of several different investments to ensure an acceptable level of risk. The allocation is clearly disclosed in all fund communications. High volatility in the commodities markets at the start of the year makes Caldwell pessimistic about returns, so he shifts the fund into emerging market and U.S. government securities, positions he maintains at the end of the year. This change is noted in the next annual report to fund shareholders. Caldwell's investment change least likely violated the CFA Institute Code of Ethics and Standards of Professional Conduct concerning:

A.diversification.

B.Communication with clients.

C.Investments outside his mandate.
