FUND INFORMATION

The Registrant is an open-end management investment company registered under the 1940 Act. Each Fund other than the Emerging Markets Equity Fund is diversified within the meaning of the 1940 Act. The Emerging Markets Equity Fund is non-diversified within the meaning of the 1940 Act. That means that the Fund may invest a greater portion of its assets in the securities of a single issuer or in the securities of fewer issuers than a diversified mutual fund. The table below sets forth information about the Registrant’s organization.

Registrant Organization


Registrant	Form of Organization	Date of Organization	Number of Funds	Shares Available for Issuance
Trust I	Delaware statutory trust	May 1, 2001	9*	Unlimited

*Trust I has 9 funds or series, five of which are offered in this SAI.

Portfolio Turnover


Fund	Fiscal Year 2023 Turnover Rate	Fiscal Year 2024 Turnover Rate
Investment Grade Floating Rate Fund	39%	171%
Short Duration High Yield Fund	65%	160%

The changes in portfolio turnover over the last two fiscal years for each Fund included in the table above were primarily due to trading strategies employed by the Fund’s portfolio management team in response to market conditions and shareholder cash flow activity, and not reflective of a material change in the Fund’s principal investment strategies. Investment Grade Floating Rate Fund is recently organized and reflects a full year of activity compared to the prior fiscal period of May 1, 2023 to July 31, 2023.

Related Additional Investment Restrictions

In addition to the principal investment strategies (and related restrictions) discussed in each Funds' prospectus, the Fund may use other investment techniques in seeking to achieve its investment objective, as set forth in the table above. The applicable investment restrictions associated with such other investment techniques are set forth below. Please see ‘‘Additional Information on Portfolio Investments, Risks, and Techniques’’ in Part II of the SAI for more information on these and the other investment techniques that may be used by the Funds.

Borrowing Money. Each Fund may borrow money to the extent permitted by its investment policies and restrictions and applicable law. When a Fund borrows money or otherwise leverages its portfolio, the value of an investment in the Fund may be more volatile and other investment risks will tend to be compounded.

Each Fund may engage in other transactions that may have the effect of creating leverage in the Fund’s portfolio, including, by way of example, derivatives transactions and reverse repurchase agreements. A Fund will generally not treat derivative transactions as borrowings of money.

Illiquid Securities. Each Fund may invest up to 15% of its net assets in illiquid securities. An illiquid security is a security that a Fund reasonably expects cannot be sold or disposed of in then-current market conditions in seven calendar days or less without the sale or disposition significantly changing the market value of the security. In determining the liquidity of an investment, a Fund may consider, among other things, the relevant market, trading and investment specific considerations of the security, including anticipated trading sizes.

A portion of the fees payable by the Fund to its Independent Board Members may be deferred at the option of a Board Member under an equity-based plan (the “deferred compensation plan”) that deems the deferred amounts to be invested in shares of the Fund for later distribution to the Board Members.
