[2] Includes state franchise taxes and federal and state income tax expenses, including deferred tax expenses (benefits). The Fund accrues a deferred tax liability (or asset) for its future tax liability associated with the Fund’s potential tax expense (benefit) if it were to recognize the unrealized gains (losses) in its portfolio. Such deferred tax expenses (benefits) may vary greatly from year to year and from day to day depending on the nature of the Fund’s investments, the performance of those investments, and general market conditions, and any estimate of deferred income tax expense (benefit) cannot be reliably predicted from year to year.
[3] Includes acquired fund fees and expenses that do not exceed 0.01% of the Fund’s average daily net assets. Acquired fund fees and expenses are not reflected in the Fund’s financial statements, so the information presented in the expense table may differ from that presented in the financial highlights.

The contractual arrangement will continue until February 28, 2027, at which time the contractual arrangement will automatically terminate (and it may not be terminated prior to that date). The Fund’s investment manager may recoup reimbursed amounts for three years after the reimbursement occurred if total expenses, including such recoupment, do not exceed the annual expense limit in effect at the time of such reimbursement or such recoupment.

The contractual arrangement will continue until February 28, 2027, at which time the contractual arrangement will automatically terminate (and it may not be terminated prior to that date). The Fund’s investment manager may recoup reimbursed amounts for three years after the reimbursement occurred if total expenses, including such recoupment, do not exceed the annual expense limit in effect at the time of such reimbursement or such recoupment.
[8] The Fund’s investment manager has contractually agreed to ensure that total operating expenses (excluding brokerage commissions, taxes, interest expense, acquired fund fees and expenses, and any extraordinary expenses) do not exceed 0.85% of the Fund’s average daily net assets.
