Under the section entitled “PORTFOLIO MANAGERS – Compensation,” the following subsection is added:

Schroders.

COMPENSATION. Schroders’ methodology for measuring and rewarding the contribution made by portfolio managers combines quantitative measures with qualitative measures. The Portfolio’s portfolio managers are compensated for their services to the Portfolio and to other accounts they manage in a combination of base salary and annual discretionary bonus, as well as the standard retirement, health and welfare benefits available to all Schroders employees. Base salary of Schroders employees is determined by reference to the level of responsibility inherent in the role and the experience of the incumbent, is benchmarked annually against market data to ensure competitive salaries, and is paid in cash. The portfolio managers’ base salary is fixed and is subject to an annual review and will increase if market movements make this necessary or if there has been an increase in responsibilities.

- 3 -

Each portfolio manager’s bonus is based in part on performance. Discretionary bonuses for portfolio managers are determined by a number of factors. At a macro level the total amount available to spend is a function of the compensation to revenue ratio achieved by Schroders globally. Schroders then assesses the performance of the division and of a management team to determine the share of the aggregate bonus pool that is spent in each area. This focus on “team” maintains consistency and minimizes internal competition that may be detrimental to the interests of Schroders’ clients. For each team, Schroders assesses the performance of their funds relative to competitors and to relevant benchmarks (which may be internally-and/or externally-based and are considered over a range of performance periods, including over one and three year periods), the level of funds under management and the level of performance fees generated, if any. The portfolio managers’ compensation for other accounts they manage may be based upon such accounts’ performance. Schroders also reviews “softer” factors such as leadership, contribution to other parts of the business, and adherence to our corporate values of excellence, integrity, teamwork, passion, and innovation. An employee’s bonus is paid in a combination of cash and Schroders plc stock, as determined by Schroders. This stock vests over a period of three years and ensures that the interests of the employee are aligned with those of shareholders of Schroders.

Capitalized terms used herein but not defined shall have the meanings assigned to them in the SAI.
