On or about February 5, 2027 (the &#x201c;Effective Date&#x201d;), the Fund will begin to invest substantially all of its assets directly in a portfolio of securities. As a result of this change, on the Effective Date, the first paragraph of the Fund&#x2019;s principal investment strategy will be deleted, and all references to the &#x201c;master portfolio&#x201d; or Real Return Portfolio, as applicable, will be removed or replaced with references to the Fund throughout the prospectus, summary prospectus and statement of additional information.&lt;/span&gt;&lt;/p&gt;</oef:SupplementToProspectusTextBlock>
