*Supplement dated December 16, 2025 to the Prospectus and Summary Prospectus,* 

*each dated October 31, 2025, as may be supplemented from time to time* 

**Effective January 15, 2026 (the "Effective Date"), the Fund's principal investment strategy will be revised to (i) replace the current Primary and Secondary Indexes with a single broader market index, (ii) remove language stating the Fund will invest approximately 50% to 75% of its net assets in Senior Loans eligible for inclusion in the Primary and/or Secondary Indexes, (iii) include investing in collateralized loan obligations, and (iv) include investing in repurchase agreements and entering into reverse repurchase agreements. Accordingly, as of the Effective Date:** 

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**1.** **The first four paragraphs of "*THE FUND ' S PRINCIPAL INVESTMENT STRATEGY*" section in the Fund's Prospectus and Summary Prospectus are deleted in their entirety and replaced with the following:** 

In pursuing its investment objective, the Fund seeks to outperform the Morningstar LSTA US Leveraged Loan Index (the "Index") by normally investing at least 80% of its net assets (plus any borrowings for investment purposes) in Senior Loans. For purposes of this 80% test, "Senior Loans" are first lien senior secured floating rate bank loans. A Senior Loan is an advance or commitment of funds made by one or more banks or similar financial institutions, including the Fund, to one or more corporations, partnerships or other business entities and pays interest at a floating or adjusting rate that is determined periodically at a designated premium above a base lending rate. A Senior Loan is senior to all unsecured claims against the borrower and senior or equal to all other secured claims, meaning that, in the event of a bankruptcy, the Senior Loan, together with other first lien claims, is entitled to be the first to be repaid out of proceeds of the assets securing the loans, before other existing claims or interests receive repayment. However, in bankruptcy proceedings, there may be other claims, such as taxes or additional advances that take precedence. Senior Loans in which the Fund may invest, may include covenant-lite loans, which may contain fewer or no maintenance covenants compared to other loans. Each of the Fund's Senior Loan investments is expected to have no less than $250 million par outstanding.

The Fund invests predominantly in Senior Loans that are made to businesses operating in North America, but may also invest in Senior Loans made to businesses operating outside of North America. The Fund may invest in Senior Loans directly, either from the borrower as part of a primary issuance or in the secondary market through assignments of portions of Senior Loans from third parties, or participations in Senior Loans, which are contractual relationships with an existing lender in a loan facility whereby the Fund purchases the right to receive principal and interest payments on a loan but the existing lender remains the record holder of the loan. Under normal market conditions, it is expected that the Fund's Senior Loan investments will maintain an average interest rate duration of less than 90 days. Loan interest rate duration is based on the actual remaining time until the applicable reference rate is reset for each individual loan. In addition, when making investments, the Sub-Adviser seeks to maintain appropriate liquidity and price transparency for the Fund.

In selecting securities for the Fund, the Fund's sub-adviser, Blackstone Liquid Credit Strategies LLC (the "Sub-Adviser"), seeks to construct a portfolio of loans that it believes is less volatile than the general loan market. In addition, when making investments, the Sub-Adviser seeks to maintain appropriate liquidity and price transparency for the Fund. On an on-going basis, the Sub-Adviser adds or removes those individual loans that it believes will cause the Fund to outperform or underperform the Index. The Fund's strategy may result in a high portfolio turnover rate.

When identifying prospective investment opportunities in Senior Loans, the Sub-Adviser currently intends to invest principally in Senior Loans that are below investment-grade quality and will rely on fundamental credit analysis in an effort to attempt to minimize the loss of the Fund's capital. While credit ratings assigned by Moody's Investors Service, Inc., S&P Global Ratings and/or Fitch Ratings Inc. (the "SROs" (statistical rating agencies)) will be considered, such ratings will not be determinative in the Sub-Adviser's process in the selection of specific debt securities (including Senior Loans). The Senior Loans and other securities that the Sub-Adviser is likely to select for investment in by the Fund will typically be rated below investment-grade quality by one or more of the SROs or, if unrated, will typically, in the opinion of the Sub-Adviser, be of similar credit quality. The Sub-Adviser expects to invest in Senior Loans, other loans and bonds of companies, including high yield securities (commonly known as "junk" bonds), collateralized loan obligations ("CLOs") and Rule 144A securities, possessing the following attributes, which it believes will help generate higher risk adjusted total returns. The Fund may also invest repurchase agreements and enter into reverse repurchase agreements for cash management purposes.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**2.** **The following discussions are added to the "*PRINCIPAL RISKS OF INVESTING IN THE FUND*" section in the Fund's Prospectus and Summary Prospectus:** 

**Collateralized Loan Obligation Risk:** The risks of an investment in a collateralized loan obligation depend largely on the type of the collateral securities and the class of the collateralized loan obligation in which the Fund invests. Collateralized loan obligations are generally subject to credit, interest rate, valuation, liquidity, leverage, prepayment and extension risks. These securities also are subject to risk of default on or modification of the underlying asset, particularly during periods of economic downturn. Collateralized loan obligations carry additional risks including, but not limited to, (i) the possibility that distributions from collateral securities will not be adequate to make interest of other payments, (ii) the collateral may decline in value or default, (iii) the Fund may invest in obligations that are subordinate to other classes, and (iv) the complex structure of the security may not be fully understood at the time of investment and produce disputes with the issuer or unexpected investment results. Collateralized loan obligations are divided into two or more classes, called "tranches," each with a different credit rating and risk/return profile. Tranches are categorized as senior, mezzanine and subordinated/equity, according to their degree of credit risk. If there are defaults or the collateralized loan obligation's collateral otherwise underperforms, scheduled payments to senior tranches take precedence over those of mezzanine tranches, and scheduled payments to mezzanine tranches take precedence over those of subordinated/equity tranches. Senior and mezzanine tranches are typically rated. The ratings reflect both the credit quality of underlying collateral as well as how much protection a given tranche is afforded by tranches that are subordinate to it.

**Repurchase Agreement Risk:** Repurchase agreements typically involve the acquisition by the Fund of debt securities from a selling financial institution such as a bank, savings and loan association or broker-dealer. The agreement provides that the Fund will sell the securities back to the institution at a fixed time in the future. Repurchase agreements may be viewed as loans made by the Fund which are collateralized by the securities subject to repurchase. If the Fund's counterparty should default on its obligations and the Fund is delayed or prevented from recovering the collateral, or if the value of the collateral is insufficient, the Fund may realize a loss.

**Reverse Repurchase Agreement Risk:** Reverse repurchase agreements involve both counterparty risk and the risk that the value of securities that the Fund is obligated to repurchase under the agreement may decline below the repurchase price. Reverse repurchase agreements involve leverage risk; the Fund may lose money as a result of declines in the values both of the security subject to the reverse repurchase agreement and the instruments in which the Fund invested the proceeds of the reverse repurchase agreement.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**3.** **The risk chart within the "ADDITIONAL RISK INFORMATION" section of the Prospectus is updated to reflect that "Collateralized Loan Obligation Risk," "Repurchase Agreement Risk," and "Reverse Repurchase Agreement Risk" are principal risks of the Fund.**
