[1] The index returns do not reflect deductions for fees, expenses, or taxes.
[2] Effective January 21, 2026, the Investment Adviser changed the secondary benchmark from the MSCI U.S. REIT® Index to the FTSE Nareit Equity REITs Index because the FTSE Nareit Equity REITs Index is considered by the Sub-Adviser to be a more appropriate benchmark reflecting the type of securities in which the Portfolio invests.
[3] The index returns include the reinvestment of dividends and distributions net of withholding taxes, but do not reflect fees, brokerage commissions, or other expenses.
