(12) Threadneedle International Limited Conflicts of Interest. Threadneedle portfolio managers may manage one or more mutual funds as well as other types of accounts, including proprietary accounts, separate accounts for institutions, and other pooled investment vehicles. Portfolio managers make investment decisions for an account or portfolio based on its investment objectives and policies, and other relevant investment considerations. A portfolio manager may manage a separate account or other pooled investment vehicle whose fees may be materially greater than the management fees paid by the Fund and may include a performance-based fee. Management of multiple funds and accounts may create potential conflicts of interest relating to the allocation of investment opportunities, and the aggregation and allocation of trades. In addition, the portfolio manager’s responsibilities at Threadneedle include working as a securities analyst. This dual role may give rise to conflicts with respect to making investment decisions for accounts that he/she manages versus communicating his/her analyses to other portfolio managers concerning securities that he/she follows as an analyst.
  Threadneedle has a fiduciary responsibility to all of the clients for which it manages accounts. Threadneedle seeks to provide best execution of all securities transactions and to aggregate securities transactions and then allocate securities to client accounts in a fair and timely manner. Threadneedle Investments has developed policies and procedures, including brokerage and trade allocation policies and procedures, designed to mitigate and manage the potential conflicts of interest that may arise from the management of multiple types of accounts for multiple clients.
(25) Threadneedle International Limited Portfolio Manager Compensation. To align the interests of our investment staff with those of our clients, the remuneration plan for senior individuals comprises basic salary and an annual profit share scheme (linked to individual performance and the profitability of the company) delivered partly as a cash incentive, and partly as a deferred long-term incentive which Threadneedle believes encourages longevity of service, split equally between Restricted Stock Units in Ameriprise Financial and reinvestment into a suite of Threadneedle’s own funds. Investment performance is a major factor within that performance appraisal, judged relative to each fund’s targets on a 1- and 3-year basis, with a bias towards 3-year performance in order to incentivise delivery of longer-term performance. Threadneedle Fund Deferral program, through which the deferral is notionally invested in a number of Threadneedle funds, vesting in three equal parts over three years, which provides a strong tie for our investment professionals to client interests.
  The split between each component within the remuneration package varies between investment professionals and will be dependent upon performance and the type of funds they manage.
  Incentives are devised to reward:
1. investment performance and Threadneedle client requirements, in particular the alignment with Threadneedle clients through a mandatory deferral into our own products; and
2. team cooperation & values.
  The split of the incentive pool focuses on the:
1. performance of the individual’s own funds and research recommendations;
2. performance of all portfolios in the individual’s team;

3. overall contribution to the wider thinking and success of the investment team, for example, idea generation, interaction with colleagues and commitment to assist with the sales effort; and
4. Threadneedle performance.
  Consideration of the individual’s overall performance is designed to incentivise fund managers to think beyond personal portfolio performance and reflects contributions made in:
1. inter-team discussions, including asset allocation, global sector themes and weekly investment meetings;
2. intra-team discussions, stock research and investment insights; and
3. a fund manager’s demonstration of Threadneedle values, as part of our team-based investment philosophy.
  It is important to appreciate that for individuals to maximise their rating and hence their incentive remuneration they need to contribute in all areas. Importance is placed not only on producing strong fund performance but also contributing effectively to the team and the wider Investment department and on the Manager’s demonstration of Threadneedle’s corporate values. This structure is closely aligned with Threadneedle’s investment principles of sharing ideas and effective communication.
  Investment professionals are formally reviewed once a year, and the performance year runs from January to December. However, we also take into consideration longer-term performance (rolling three and five years) together with a manager’s contribution to the investment dialogue and desk success and their control of and adherence to our risk controls.
The rest of the section remains the same.
Shareholders should retain this Supplement for future reference.
