REITs – Real Estate Investment Trusts
At September 30, 2024, the Fund had sufficient cash and/or securities to cover commitments under open derivative contracts.
The Fund is subject to equity price risk in the normal course of pursuing its investment objectives. The Fund writes index call options above the current value of the index to generate premium income. In writing index call options, the Fund in effect, sells potential appreciation in the value of the applicable index above the exercise price in exchange for the option premium received. The Fund retains the risk of loss, minus the premium received, should the value of the underlying index decline.
Affiliated Investments
At September 30, 2024, the value of the Fund's investment in funds that may be deemed to be affiliated was $663,840, which represents 0.1% of the Fund's net assets. Transactions in such investments by the Fund for the fiscal year to date ended September 30, 2024 were as follows:

Fair Value Measurements
Under generally accepted accounting principles for fair value measurements, a three-tier hierarchy to prioritize the assumptions, referred to as inputs, is used in valuation techniques to measure fair value. The three-tier hierarchy of inputs is summarized in the three broad levels listed below.
Level 1 – quoted prices in active markets for identical investments
Level 2 – other significant observable inputs (including quoted prices for similar investments, interest rates, prepayment speeds, credit risk, etc.)
Level 3 – significant unobservable inputs (including a fund's own assumptions in determining the fair value of investments)

Portfolio of Investments (Unaudited) — continued

In cases where the inputs used to measure fair value fall in different levels of the fair value hierarchy, the level disclosed is determined based on the lowest level input that is significant to the fair value measurement in its entirety. The inputs or methodology used for valuing securities are not necessarily an indication of the risk associated with investing in those securities.
At September 30, 2024, the hierarchy of inputs used in valuing the Fund’s investments and open derivative instruments, which are carried at fair value, were as follows:
Asset Description  Level 1 Level 2 Level 3 Total
Common Stocks $460,038,258* $    — $    — $460,038,258
Short-Term Investments     663,840     —     —     663,840
