Compensation (Northern Cross)

The four principals of Northern Cross, Messrs. Appleby, Ducrest, LaTorre and Wendell are equal owners of the firm and its founding partners. Their compensation consists of equal shares in the firm’s overall profits.

Conflicts (Northern Cross)

From time to time, potential conflicts of interest may arise between the portfolio managers’ management of the investments of the Multi-Manager International Fund, on the one hand, and the management of other accounts, on the other. The other accounts might have similar investment objectives or strategies as the Multi-Manager International Fund, track the same index that the Multi-Manager International Fund tracks or otherwise hold, purchase, or sell securities that are eligible to be held, purchased or sold by the Multi-Manager International Fund. The other accounts might also have different investment objectives or strategies than the Multi-Manager International Fund.

Knowledge and Timing of Portfolio Trades. A potential conflict of interest may arise as a result of the portfolio managers’ day-to-day management of the Multi-Manager International Fund. Because of the portfolio managers’ positions with the Multi-Manager International Fund, each portfolio manager knows the size, timing and possible market impact of the Multi-Manager International Fund’s trades. It is theoretically possible that a portfolio manager could use this information to the advantage of other accounts he manages and to the possible detriment of the Multi-Manager International Fund.

Investment Opportunities

A potential conflict of interest may arise as result of a portfolio manager’s management of a number of accounts with varying investment guidelines. Often, an investment opportunity may be suitable for both the Multi-Manager International Fund and other accounts managed by one or more of the portfolio managers, but may not be available in sufficient quantities for both the Multi-Manager International Fund and the other accounts to participate fully. Similarly, there may be limited opportunity to sell an investment held by the Multi-Manager International Fund and another account.

Northern Cross has adopted policies and procedures reasonably designed to treat all accounts fairly and equitably and to address the potentially adverse effect of any conflicts of interest. Northern Cross has adopted policies and procedures designed to allocate investment opportunities on a fair and equitable basis over time. Under these allocation procedures, investment opportunities are allocated among various investment strategies based on account investment guidelines and the Sub-advisor’s investment outlook.
