In the normal course of pursuing its investment objective, the Fund is subject to the following risks:

Interest Rate Risk: Because the Fund holds fixed-rate bonds, the value of these bonds may decrease if interest rates rise. The Fund utilizes futures contracts and interest rate swaps and swaptions to enhance total return, to change the overall duration of the Fund and/or to hedge against fluctuations in securities prices due to changes in interest rates.

Reverse Repurchase Agreements

Reverse repurchase agreements outstanding as of January 31, 2024 were as follows:

Counterparty	Trade Date	Maturity Date	Interest Rate Paid (Received)	Principal Amount	Value Including Accrued Interest

Total				$455,920,151	$458,145,127

⁽¹⁾	Open reverse repurchase agreement with no specific maturity date. Either party may terminate the agreement upon demand.

At January 31, 2024, the remaining contractual maturity of all open reverse repurchase agreements was overnight and continuous. At January 31, 2024, the underlying collateral for all open reverse repurchase agreements was $533,403,949, comprised of cash of $6,000,000 and agency mortgage-backed securities having an aggregate market value of $527,403,949.

Based on the short-term nature of the borrowings under the reverse repurchase agreements, the carrying value of the payable for reverse repurchase agreements approximated its fair value at January 31, 2024. If measured at fair value, borrowings under the reverse repurchase agreements would have been considered as Level 2 in the fair value hierarchy at January 31, 2024.

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)

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.
